EPA Warns Against Use of Refrigerant Substitutes That Pose Fire and Explosion Risk

FOR IMMEDIATE RELEASE
July 1, 2013

WASHINGTON – The U.S. Environmental Protection Agency (EPA) is warning homeowners, propane manufacturers and sellers, home improvement contractors and air conditioning technicians of potential safety hazards related to the use of propane or other unapproved refrigerants in home air conditioning systems.

EPA is currently investigating instances where propane has been marketed and used as a substitute for HCFC-22 (R-22), a refrigerant that is widely used in home air conditioning systems.

Home air conditioning systems are not designed to handle propane or other similar flammable refrigerants. The use of these substances poses a potential fire or explosion hazard for homeowners and service technicians. 

EPA is aware of incidents that have occurred both overseas and in the U.S. where individuals have been injured as a result of the use of propane and other unapproved refrigerants in air conditioning systems. We are investigating and will take enforcement actions where appropriate. Other names for these unapproved refrigerants include R-290, 22a, 22-A, R-22a, HC-22a, and CARE 40.

At this time, EPA has not approved the use of propane refrigerant or other hydrocarbon refrigerants in any type of air conditioner. Homeowners and technicians are strongly recommended to limit use of propane or other hydrocarbons to only those appliances specifically designed for these substances and that are properly marked to alert technicians that the equipment contains a flammable substance. EPA has approved the use of propane as a substitute refrigerant for R-22 in industrial process refrigeration systems and in new, stand-alone retail food refrigerators and freezers that are specifically designed to use flammable hydrocarbon refrigerants.

R-22 is being phased out of production and importation under the Montreal Protocol, an environmental treaty ratified by every country in the world designed to reduce and eventually eliminate the use of ozone depleting substances. EPA’s Significant New Alternatives Policy (SNAP) Program has already listed numerous refrigerants with improved environmental, health and safety profiles and continues to evaluate other refrigerants that can be used to replace R-22 and other ozone-depleting substances.

Renewed interest in HC heat pumps in Europe – exclusive interview with D. Colbourne

The increasing availability in Europe of optimised R290 compressors for heat pumps is reviving interest in the technology. During the UNIDO ATMOsphere Technology Summit, hydrocarbons21.com interviewed Mr. Daniel Colbourne, Consultant at Re-phridge, about the historical development of hydrocarbon (HC) heat pumps and the current state of play in Europe.

hydrocarbons21.com: In the 1990s there were several hydrocarbon-based heat pump products for domestic application in the EU market, which subsequently disappeared. What in your view might have caused this?

Daniel Colbourne: There were many hydrocarbon (HC) heat pump products on the European market; Austria, Switzerland, Scandinavia and Germany, mainly from small and medium sized producers. But the EU Pressure Equipment Directive (PED) was introduced which basically states that the components and piping in the refrigeration system must be designed, tested and approved for that particular refrigerant (or refrigerant “group”). The PED requirements for flammable refrigerants are one level above those for the non-flammable, low toxicity fluid “group”, which includes refrigerants like R22.

Previously many companies were taking R22 compressors and adapting them for use with R290. So when the PED came into force it essentially meant that they could no longer utilise those R22 compressors; i.e., they could only use R290 compressors for R290. At the time there were no manufacturers producing the right type of R290 compressors and, since in order to certify compressors for R290, additional approval processes are necessary (which in some cases are costly), the size of the market was evidently not sufficient for manufacturers to justify it. For example, the person that is welding the compressors has got to have a higher level of certification, which implies additional investments for the compressor manufacturers.

So the heat pump manufacturers apparently had little choice, all they could do was to switch to an alternative which was not a flammable refrigerant. I would say that was the main reason for the decline. Given the extensive literature demonstrating the comparatively higher efficiency of R290 and the excellent safety record, it was not performance or hazardous aspects that were responsible.

A number of manufacturers continued with some R290 models (and still do today) in particular for smaller capacity units where R290 hermetic compressors normally used for commercial refrigeration are suitable. Nonetheless, this represents a relatively small portion of the market.

hydrocarbons21.com: In terms of performance and reliability, how were these R290 products performing?

Colbourne: With regards to reliability, when R22 compressors were initially used there were some problems. However, a study presented by a major German player on the development of their R290 heat pumps in 1999 stated that after optimisation of the compressor oil, the reliability of their R290 heat pumps was better than that of their R22 heat pumps. Of course, many companies are currently selling R290 heat pumps, which would not be the case were there reliability issues.

Throughout that period there were many studies published on the efficiency of hydrocarbons in heat pumps and most of them said that R290 performance was at least as good, typically much better than the other alternatives (for space heating purposes). Both the large volume of technical literature and publications from different manufacturers support this. Furthermore, when considering the thermophysical properties of HCs, it is fairly obvious; not only do the thermodynamic properties demonstrate this but also the excellent viscosity and thermal conductivity infers better component performance than most other fluorinated alternatives.

hydrocarbons21.com: More recently do you see a renewed interest in the use of hydrocarbons in heat pumps by European manufacturers?

Colbourne: In general we can see increasing pressure to use heat pumps in Europe as they are seen as a means for accelerating CO₂ emission reduction. Within this context it seems rather daft to not use low-GWP refrigerants or particularly natural refrigerants for those types of products where they can be used. There are a fairly large number of manufacturers within Europe (but also Australia and China) that are currently using HCs (as well as other natural refrigerants). In this respect there is increasing interest in some quarters, but of course others are also resisting.

The safety issue is surely already addressed, since relevant safety regulations and standards are available and have been for many years.

hydrocarbons21.com: Heat pump manufacturers often state that the reason they do not offer HC-based heat pumps is that they cannot find optimised HC compressors or other components for the purpose. What would you recommend to the industry for overcoming this barrier?

Colbourne: On the compressor side, at least two major compressor manufacturers are now producing compressors specifically designed and optimised for R290 heat pump systems, implying that this barrier is now becoming resolved. Moreover, there are several companies that make other components, such as controls for hydrocarbons that can be used in heat pumps. These enterprises obviously see that there is a market and they would not invest large sums in the technology unless they had confidence in it.

Beware of Flammable R-22a Refrigerants!

June 12, 2013

With the phaseout of the refrigerant R-22, dangerous replacements are surfacing. Steer clear of purchasing highly flammable products sold that are listed in a form of 22a Refrigerant, as the gas can burn or even explode when in contact with an ignition source.

There is great concern over the flammability of these products, when used as a refrigerant in air conditioning equipment. The U.S. Environmental Protection Agency (EPA) has a Significant New Alternatives Policy (SNAP) that maintains lists of acceptable refrigerants in listed applications. EPA has issued some Frequently Asked Questions (FAQ’s) regarding these R-22a products, click here to read these FAQ’s.

These products could pose significant safety risks to homeowners and technicians. Unknowing homeowners who have used this product may have created an exposure to fire or explosion should a leak be present in the home. Technicians that have not been informed of the use of these products face similar risks in that their service equipment is not designed for these products. Inadvertent mixing of recovered gases may contaminate a contractor’s bulk recovery cylinder forcing disposal of the product in place of reclaiming.

There are many approved replacement refrigerants being marketed today; contractors should carefully consider the products they wish to use. For a list of EPA approved alternate refrigerants for residential air conditioning, click here.

Remember, it is illegal for anyone to intentionally mix refrigerants in equipment or to intentionally vent refrigerant to the atmosphere. Use alternate refrigerants wisely; do not top off a system with an alternate refrigerant.

Coming to America

U.K.'s A-Gas Plans Expansion Into North America

A-Gas’s acquisitions in the U.S. will set it up for a significant expansion into North America, including the international rollout of its refrigerant reclamation technology.

This year, A-Gas celebrates its 20th year in business, but no time in those two decades has been quite as busy as last year. The past 12 months have seen intense activity as the Bristol refrigerant distributor and reclaimer bought two U.S. specialists, Coolgas and RemTec, and set up a fully fledged North American division. The firm has transplanted U.K. managing director Ken Logan to oversee the establishment of the U.S. operations for the next two years at least.

The acquisition of the U.S. businesses, plus a further distributor in Australia, Technochem, has seen the A-Gas Intl. group top £100 million turnover for 2012, with a worldwide headcount of 237.

Acquiring Assets

“A-Gas is now the largest independent refrigerant player outside of the U.S.,” said Jon Masters, European managing director. “Our core territories are in the U.K., South Africa, and Australia, in each of which we have a 30-35 percent market share. So we were keen to try and take that offering to the U.S. — it was the right opportunity in terms of the business and the regulatory framework.”

That framework is the U.S. phase out of HCFCs and the probable phase down of HFCs, expected to closely follow the European Commission’s proposed F-Gas model — although progressive states like California are already bringing in more stringent rules.

The particular attraction of RemTec is that its core business is halon reclamation. Although these are largely from fire suppressants, this offers the right range of skills and technology to allow an expansion into refrigerant reclamation. This is where A-Gas brings its own skills to bear, said Masters. “We can bring our reclamation knowhow, and the benefit of the U.K. experience of selling the reclaimed HCFC product. The U.S. market is maybe four or five years behind Europe, but it is rapidly developing, and the EPA [Environmental Protection Agency] has announced more cuts in HCFC volume.”

The plan is for the RemTec operation to be brought up to the same standard for refrigerant reclamation as A-Gas’s Bristol facilities by the end of this year.

The commercial implications of the rapid cuts should not be underestimated; in the U.S. over the past year, virgin R-22 has increased in price from $3 per pound to $15 per pound.

Coolgas, by contrast, is a conventional refrigerant distributor, but again the purchase is strategic, providing a foothold in the Southwest, from which A-Gas can build, with a brand name well known to the American market. It also holds all-important import rights to HCFCs.

A foothold in such a large territory is a big deal in its own right, but the potential is far bigger. “The U.S. business is roughly the same size as the U.K. business, but whereas in the U.K. that brings a 30 percent market share, in the U.S. it is only 2 percent of the market. It should be easier to double from 2-4 percent than from 30-60 percent.”

If the plans for reclamation at RemTec go well, it could be joined by other sites. While the U.K. can function well with a single reclamation site, the scale of the U.S. is likely to require a network of two or three more. With reclaimed HCFC expected to be useable in the U.S. beyond 2020, that is an attractive long-term target.

Reclamation Technology

In a relatively short time, refrigerant recovery and reclamation has become a serious business for A-Gas. Its environmental services operations now account for around 20 percent of turnover (refrigerants is the largest proportion at 60 percent).

U.K. business director John Ormerod said, “What we do falls into two areas: cleaning up dirty gas by removing contaminants and separating out gases from refrigerant mixtures.

“We probably lead the world in refrigerant reclamation. There is only one other company in the U.K. and three in the U.S. who can separate refrigerants like we do,” he said.

The separation facilities at Bristol have come on apace since the pioneering days when its technology could be housed in a corner of the warehouse. The original plant is still in situ, but it has been joined by Separator 3, located outside the warehouse and large enough to be able to accommodate tanker-sized volumes of refrigerant, with a capacity to process around 400 tonnes a year.

Although the precise technology is secret, both plants are designed to reclaim refrigerant to Air-Conditioning, Heating & Refrigeration Institute (AHRI) 700 standards, as well as being able to split mixed refrigerants into usable batches and to reclaim individual gases from cocktails of recovered refrigerant. The latter is where A-Gas claims distinctiveness, as “the only supplier who has both the technology and the capacity to provide this level of service.”

Industry Encourages Cap Use on Refrigerants

Recent Deaths Demonstrate Dangers of Huffing R-22

By Peter Powell

 

This past March, Kristal Salcido, a 12-year-old seventh grader in Victorville, Calif., inhaled HCFC-22 from an air conditioning unit in the backyard of her grandmother’s home. She was later found passed out on the bathroom floor. Rushed to the emergency room, Salcido was pronounced brain dead. Four days later, her family decided to take her off life support.
She had used the R-22 in a ritual called huffing — the intentional inhalation of chemical vapors to attain a mental high or euphoric effect.
Refrigerants such as CFCs, HCFCs, HFCs, and propane are just part of that chemical basket of inhalants. Others are gasoline, paint thinners, nail polish, and nitrous oxide. According to the website www.inhalants.org, one in five students has inhaled a chemical to get high by the eighth grade.

The Hazards of Huffing

In the case of the R-22, “When you inhale it, it kills your brain cells — that’s all,” said Ron Postoian, president of AC Plus Heating & Air of Hesperia, Calif., who was interviewed by television station KTLA for its story on a recent huffing fatality in his home state.
“People really don’t realize how dangerous this is,” said Dr. Craig Sanford, Tulsa, Okla., in a news report broadcast by NewsOn6. “Inhaling this substance prevents the body from getting oxygen and you can get frostbite from it, inside the tissues of your nose, mouth, and face.”
Postoian said that he’s serviced a number of condensing units where the refrigerant had suspiciously been used up.
That “missing refrigerant” aspect was echoed by Ryan Rentmeister, who owns Rentmeister Total Home Service of Salt Lake City. A few years ago in his hometown, people were turning on their air conditioners, but the machines were failing to provide cool air, due to absent refrigerant. “We’ve had four cases in the last week,” he said, suspecting huffing as the cause.
Ronda Szymanski of Advanced Air and Refrigeration Inc., Fort Myers, Fla., said a telltale sign is when service techs find a butter knife laying next to a central air conditioning condenser that has been depleted of refrigerant, with its service port visibly damaged.

Curbing the Problem

Regulators and many within the HVACR industry have been working hard to get a handle on this deadly situation. Both the International Mechanical Code 1101.10 and the International Residential Code M1411.6 have mandated that “refrigerant-circuit access ports located outdoors shall be fitted with locking-type tamper-resistant caps.”
Code requirements have been in place since 2009, but these requirements need to be codified by each state, said Gerry Spanger, director of HVACR engineered products for Rectorseal Corp.
So far, at least five states have adopted the codes, said Spanger. However, limiting more widespread acceptance, the codes are only related to new construction. He said eventually the codes will extend into retrofits and existing buildings. “It is not a question of ‘no, this won’t happen.’ It is just a question of how long it takes,” said Spanger.
Once state codes are in place, inspectors cannot sign off on a job until the locking caps are in place.
“The products are a must for companies and technicians to comply with local codes as well as liability concerns connected with refrigerants,” said Oscar Lopez, vice president of sales for JB Industries Inc., Aurora, Ill.
Spanger said that even as all the regulatory aspects eventually fall into place, there is still the possibility of abuse within the HVACR sector. He said he’d even heard of contractors buying the caps, locking them in place when required, and then removing them after an inspection for use in the next project.
“They don’t understand they are laying themselves open to liabilities,” he said.
He also said that even though the caps can only be sold to contractors who are U.S. Environmental Protection Agency (EPA)-certified to handle refrigerants, he had heard of instances of some wholesalers and contractors who sell the caps on websites, even though they may not be able to verify the certification status of the purchaser.
According to Jon Melchi, director of government affairs for Heating, Air-conditioning & Refrigeration Distributors International (HARDI), “Wholesalers and suppliers strongly believe that these products should not be available online. They should only be sold to licensed contractors. As an industry we must be diligent in making sure that the entire channel is aware of best practices regarding these products.”

Locked and Loaded

While controlling huffing remains a key aspect of locking caps, the devices have long been offered in the HVACR distribution channel for a number of applications. Even as regulations move toward the requirement of locking caps, the devices themselves are being fine tuned.
For example, this past February, Rectorseal Corp. introduced its GasGuard™, a tamper-resistant locking valve cap designed to help prevent refrigerant theft, leaks, and huffing. It screws and locks onto threaded refrigerant Schraeder valves.
“GasGuard restricts unauthorized access because it can only be installed or removed with a unique matching proprietary socket tool,” said Jerry Tomasello, director of marketing for RectorSeal. “It cannot be removed with a core remover or Allen wrench.”
JB’s Lopez also noted that his company is launching a new American-made refrigerant safety cap with greater security under the brand name The Shield.

Contractor Support

Numerous contractors, including Chase Tunnell, president, Dominion Service, Richmond, Va., are strong advocates of locking caps. For a number of years, Tunnell has been involved with the Substance Abuse Free Environment (SAFE) program, which encourages the use of locking caps.
“SAFE is still actively pushing it and Dominion Service is currently doing a public service campaign in the Hampton Roads, Va., area,” he said. “Our Richmond division has had huge success with the program but Hampton Roads has been a little slower to catch on. We are working on fixing that.
“We are currently installing 10-15 caps each week. We’re confident that number will increase significantly as the summer season hits.”

 

 

Counting down to the ban on R22

As the months pass towards the total ban on the use of R22 for servicing air-conditioning equipment, Kevin Groves of Ergro gives his perspective.

The final removal of the HCFC refrigerant R22 from the world’s air conditioning systems has long been heralded and is now upon us here in the UK. Manufacturers of equipment have not included it in new systems since 2003. In 2010 the use of virgin R22 refrigerant was banned, and systems can only now be serviced utilising reclaimed refrigerant for maintenance. Now the final date in the legislative removal of recycled R22 because of its ozone-depleting properties is near. On 1 January 2015, the use of recycled R22 refrigerant will be banned in the EU.

Practically speaking, where R22 refrigerant is in use, there are two main options to make an air-conditioning system serviceable after the ban comes into force. One option is to convert the existing system to enable it to operate using a legal but often less efficient refrigerant or replacing part of or the entire system.

There are two main routes to a conversion solution.

In some cases it will be possible to make a few modifications to the system, such as replacing some gaskets and the oil, which will enable it to run on a new refrigerant such as R422D. This is known as the drop-in refrigerant option, which, in most cases, will lead to a reduction in cooling capacity and increased running costs.

Where another refrigerant cannot be dropped in, there may be the potential to convert the system by installing new fan coils or condensers whilst still retaining much of the building’s existing internal infrastructure such as piping. As well as increasing system capacity, conversion is likely to improve the overall efficiency of a system through the use of modern refrigerants (except when using the drop-in option).

Both solutions are, however, heavily dependent on site, installation conditions and age of the plant.
Systems not suitable for conversion will need to be replaced. Despite the higher installation costs, replacement can lead to greater system efficiencies, lower maintenance requirements and reduced operating costs.

For building-services engineers, the effect of the legislation is likely to mean that air conditioning will take centre stage in many of their operations in the coming years. It’s important that the engineering community understands what is business-critical air conditioning and impresses the importance of preparedness upon facilities managers and business leaders.

Who should act and when, what market forces and liabilities are involved and why it’s becoming the most important news in air conditioning may not be immediately obvious to many business leaders and even facilities managers. In fact, many people who could be affected most acutely won’t even know if R22 is used in their air conditioning or even realise they are responsible for the air conditioning in the spaces they occupy.

At a recent summit in London, held at the Royal Society of Medicine, Ergro assembled a panel of experts to answer some of these questions and to raise awareness of the issues surrounding the ban of R22.

The panel introduced the subject from their various perspectives and took questions from an invited audience comprising building managers, consultants, architects and business leaders.
There were several points upon which the panel was in complete agreement, chief among which was the need for people to gain the knowledge required to properly evaluate their position in relation to a date which, while it seems distant, taken in the context of the financial cycles and business-critical nature of the systems involved, is actually almost upon us.

I represented Ergro on the panel to offer the insight of a contracting engineer who works with air conditioning for skyscrapers, manufacturing, data centres and offices. Also on the panel were representatives of leading air-conditioning manufacturers Mitsubishi Electric and Daikin, legal and liability expertise from property law firm Taylor Wessing and chartered accountants and chartered tax advisors LB Group.

One question concerned the subtleties of supply and demand of the refrigerant itself. R22 is presently trading at around £30 per kilo in the UK, and this price is rising all of the time. When considering the fact that it will become illegal to buy or sell from the end of 2014 it would seem likely that the upward trend in its value will continue.

And what about installing new equipment? If it’s critical to the business that maintenance is possible and downtime avoidable, as it is in many of the instances where an estimated 750 000 systems using R22 exist, then a lot of companies will be looking to replace equipment at around the same time.
Needless to say, where demand outstrips supply in terms of the expertise to fit new systems, there are likely to be delays that could cause unnecessary risk to business continuity.

While it does seem to be a little way off, the R22 refrigerant ban will very soon make its presence felt across the business community. From now and for the next 18 months and beyond, building-services engineers will be at the heart of making business-critical systems compliant and serviceable into the future. But the whole facilities management and building services industry must come together with manufacturers and business services to help the business community to understand how the changes will affect them. Knowledge is power, and a full evaluation of existing systems will equip business leaders with the knowledge to make the right decisions to get ahead of the ban. More information and a countdown to the ban clock is available at the link below.

Update: Car engineers pour cold water on Daimler refrigerant fire claims

29 April 2013 | By Andrew Gaved

Car engineering research group SAE International has reported the conclusions of its extensive analysis of HFO 1234yf, calling the refrigerant “safe and effective to use in automotive applications” - free to view, simply register

The team on SAE’s Cooperative Research Programme, comprising most car manufacturers from Ford to Renault to Toyota, concluded that “the risk of passenger exposure to a vehicle fire associated with this refrigerant is exceptionally remote”.

The CRP was established to examine Mercedes owner Daimler’s claims that HFO 1234yf ignited in a staged head-on collision, whereas the previous refrigerant R134a, outlawed by the Mobile Air Conditioning directive, did not.

In the wake of lurid claims about the risk of flammability in the UK tabloid press, the SAE said CRP team members had again concluded that the refrigerant release testing conducted by Daimler is unrealistic, following numerous additional tests of various types to study ignition of an HFO 1234yf leak in a crash-damaged vehicle.

In another strongly worded statement, SAE said Daimler’s test “is not an appropriate test to verify the safety of refrigerant applications in vehicles. The Daimler testing did not include any actual vehicle collisions or the mitigating factors that occur in an actual collision.”

It said these factors include the quenching effect of front end compartment deformation, the extinguishing effect of steam released due to radiator breakage, and dispersion of the refrigerant from the condenser outside the engine compartment.

“Daimler’s refrigerant release apparatus and nozzle does not represent actual crash-damaged refrigerant lines, and was found to be artificial.”

The report was welcomed by Honeywell Fluorine Products, the manufacturer of the HFO, which emphasised that even those German manufacturers which have indicated they are in favour of using CO2 in the future cars had not found anything unsafe about the HFO.

Honeywell European managing director Paul Sanders said: “Pretty much all of the car industry has said publicly it can use 1234yf safely, including all members of the [German carmakers group] VDA, apart from Daimler. Opel had its test programme undertaken by engineering body TUV (above), which is globally respected.”

Following the report, Mr Sanders said Honeywell was now calling for the European Commission to censure Daimler for continuing to defy the MAC Directive. If strictly applied, the EC could forbid the registering of non-compliant cars, such as the Mercedes A and B class models which are still being produced with R134a, in contravention of the directive.

He said: “All we can ask is that the law is adhered to. The MAC directive is unequivocal that non-compliant cars should not be registered. The car industry has had seven years to make a compliant vehicle. HFO 1234yf is available today, it meets the MAC directive and it is cost-effective.”

Mr Sanders also claimed that Daimler’s preferred refrigerant carbon dioxide – which it has asked the EC for more time to develop – is not as environmentally friendly as HFO 1234yf across the lifetime of a vehicle.

He said: “CO2 is a smokescreen and it is three to five years away at best. As it is an asphyxiant it would need significant changes to car designs and the service charges would be higher, since if it was to leak, it would all leak at once.”

He warned that the Commission needed to take action against Daimler or risk appearing ineffectual: “It sets a dangerous precedent for the forthcoming F-Gas regulations if one company is allowed to go its own way and flout the law. Allegedly Daimler is saving 50 euros a car for not using 1234yf.  It is not a safety issue, it is a political issue.”

Products Helpful in Recovery, Reclamation

By Peter Powell

April 8, 2013

While the reclamation process may not be meeting industry expectations, numerous manufacturers are offering equipment and devices that make the process easier than ever before. Listed below are a few of the industry’s newest products and technologies benefiting recovery and reclamation.

Atlantic Chemical & Equipment Co.’s (www.atlanticchemical.com) ACESeal AC/R and HVAC/R leak solutions seals small (up to 300 microns) leaks in condensers, evaporators, and refrigerant lines. The AC/R can handle up to 1.5 tons while the HVAC/R can handle up to 5 tons. The AceSeal is not a polymer-based sealant, so no drying agent is required. In addition, it does not require evacuation of refrigerant to input sealant, and the sealant blends with oil/refrigerant mix to travel to the leak. The oil and refrigerant escape through the lead while larger molecules in the sealant bond together to seal.

Fieldpiece Instruments’ (www.fieldpiece.com) SMAN4 is a four-port, wireless digital manifold that has a 3/8-inch port for evacuations and recovery. The four ports allow technicians to evacuate a system, pull a vacuum, add refrigerant, and dial in the charge at one time without having to hook or unhook any hoses.

Fluke Corp.’s (www.fluke.com) CNX Wire System wirelessly connects multiple measurement modules and sends simultaneous readings to a master device up to 20 meters away, allowing users to troubleshoot problems. The customizable tool set allows users to choose various measurement modules based on their specific troubleshooting scenario to read the measurements outside the arc flash zone.

General Tools & Instruments’ (www.generaltools.com) digital refrigerant leak detector (RLD400), which features a semiconductor sensor lifespan of more than 300 hours of operation or 10 years normal use. Three sensitivity levels let users choose the right level for specific environments.

Hilmor’s (www.hilmor.com) electronic gauge with vacuum sensor is a hybrid gauge with both analog and digital readouts with lights color coordinated to the selected refrigerant. It also features a micron gauge, self calibration, and is accurate to within 1 percent. The company also recently introduced a dual readout thermometer with thermocouple clamps that can be attached to any manifold using the hook provided. The tool features two digital temperature readouts so calculating superheat and subcool no longer requires multiple tools. An aluminum manifold has a forged aluminum body with rubberized handles, protective gauge boots, replaceable stainless steel valve stems, and a pressure indicator ring that allows users to mark a spot with a marker.

Polar Technology (www.refrigerantauthority.com) recently introduced TrakRef®, a proprietary and comprehensive refrigerant management program. As explained by the company, the product is designed to provide comprehensive and transparent tracking and management of refrigerants throughout their entire lifecycles. This includes from the time of purchase to deployment throughout maintenance cycles, through recovery and reclamation, to their final destruction at the end of the lifecycle. When the program is incorporated among the participating points in the supply chain, more of the original refrigerant is kept within the supply chain, ownership of the refrigerant can be accounted for, and regulatory compliance is inherently managed. It is available in three customized versions for contractors, distributors, and system owners.

Refco Mfg. Ltd.’s (www.refco.ch) Enviro is a one-knob operation refrigerant-recovery machine. It allows for recovery of all popular CFC, HCFC, and HFC refrigerants using an oil-less, air-cooled compressor. The Enviro is equipped with a self-purging mode as well as a built-in filter.

RefTec Intl. Systems LLC‘s (www.reftec.com) BullDog recovery/recycle/reclaim unit is available in three sizes, the unit processes R-22, R-134a, R-410A, R-11, R-123, and other common refrigerants with the same unit. It processes gas at speeds of 600 pounds per hour. Features include zero cross contamination of compressor oil to gas, portable design so it fits through standard 36-inch doorways, and single power source for unit and controls. The 80 percent tank-full float switch and 12-foot float cable ensure cylinders are not being overfilled.

Robinair (www.robinair.com) introduced the RG3000 Cube, a compact and lightweight refrigerant recovery machine from Promax. It is designed for liquid and vapor recovery of commonly used CFC, HFC, and HCFC refrigerants including R-410A. Equipped with a high-pressure shift-off switch, the machine automatically shuts off if pressure rises above 550 psi, helping to prevent pressure building in a tank or machine. The high-efficiency, cross-flow airflow design allows for more efficient refrigerant recovery leading to shorter cycle times, the company said. The company also displayed a refrigerant recovery, recycle, evacuate, and recharge machine. It can be used for multiple refrigerants. The portable machine’s microprocessor-controlled functions prompt the user through programming and signal preventive maintenance. The float chamber auto adjusts from liquid to vapor. The lockout panel prevents mixing of refrigerants. The heavy-duty filter drier removes moisture and acid from the refrigerant; it can handle 300 pounds between changeovers. The Promax® Cube™ refrigerant-recovery machine is capable of recovering both liquid and vapor refrigerant. The machine has a 1/3-hp, single-cylinder oil-less compressor.

Spectronics Corp.’s (www.spectroline.com) Optimax 400 leak-detection flashlight features power comparable to high-intensity, 150-W lamps, and an inspection range of up to 25 feet.

SuperCool’s (www.supercoolsliderule.com) Slide Rule is an R-22 and R-410A charging and duct calculator that performs superheat, subcooling, and duct calculations in one tool. Fixed meter-device charging is provided for R-22 and R-410A. TXV charging is also provided for R-22 and R-410A.

Superior Signal Co. LLC (www.superiorsignal.com) introduced the AccuTrak® VPE-GN ultrasonic leak detector with a 9 ½-inch gooseneck. The unit is sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called heterodyning, it translates the sound to a lower frequency which human ears can interpret, said the manufacturer. The device maintains the original sound characteristics, making it possible to distinguish leaks from other background sounds. The leak detector is designed to pinpoint leaks in air conditioning and refrigeration systems, acknowledging present air, vacuum, refrigerant, or gas leaks.

Reclamation Looking for Jumpstart

By Peter Powell

April 8, 2013

Reclamation is in a rut. Shortly after the arrival of the Montreal Protocol, 25 years ago, came the 3 R’s: Recover, Recycle, and Reclaim. Service technicians would recover refrigerant to avoid fines for illegal venting. They’d then run the gas through an on-site recycling machine to clean it up a bit. But if they were not sure how pure the stuff they were planning to put back into the system was, they would put a virgin version of the same refrigerant into the system and send the old stuff to off-site reclamation facilities, to be brought back to the certified highest level of purity — ARI 700. The reality is that in 2012, and thus far in 2013, few technicians and contractors are bringing R-22 back for reclamation despite an abundance of capacity at many reclamation facilities. “Based on the U.S. Environmental Protection Agency (EPA) report, the amount of R-22 reclaimed year over year has remained relatively flat for the past five to six years, hovering around 5 or 6 percent of HCFC-22 demand,” said Debra D. Goodge, refrigerant reclaim programs manager for DuPont. “Beginning in 2010 with the issuance of the Final Rule (regarding phase out of R-22), there was an expectation that reclaim would be needed to fill a projected R-22 supply-demand imbalance — somewhere in the neighborhood of 27.5 million pounds each year. For the past two years, there has not been an uptick in the amount of reclaimed R-22 going through reclaimers. It’s remained steady around 8 million pounds.” Christopher Foutz, marketing manager, Honeywell Refrigerants, said, “The amount of R-22 reclaimed in 2011 was similar to the amount of R-22 that was reclaimed in 2006.”

What’s the Problem?

“One of the major contributors to the flat or declining recovery rate is that many R-22 users have adopted a practice of reusing their recovered refrigerant,” said Gordon McKinney, vice president and COO, ICOR Intl. “Even though some might be making an attempt to recycle (filter out particulates and/or separate out oils), without properly analyzing the recovered gas to determine composition and quality, the user and equipment owner are rolling the dice.”

Walt Baker, vice president of sales and marketing, Polar Technology, said, “A lot of this can be attributed to the commodity nature of refrigerant gases. Supplies are plentiful and prices reflect the availability of supplies. Therefore, the role of reclaim has been relegated to philosophies regarding environmental stewardship.”
Then there is the economics of reclamation for the contractor, said Ken Beringer, senior vice president of Airgas Refrigerants Inc. “The industry has not seen a significant increase in returned R-22 because, in my opinion, the majority of the product is harvested in small batches which do not have a great deal of value. Until January 2012, the returned gas had very little value and, in many cases, there was a disposal charge when the product was returned.”

Patti Conlan, who manages the reclaim program for Arkema, said, “In the past, the volume of reclaim has been low due to monetary gains not being passed down to the contractor level as an incentive to reclaim, as well as the possible legal and illegal reuse of R-22.”

Yet awareness is growing, said James Sweetman, president, Consolidated Refrigerant Solutions. “We have seen heightened awareness among contractors regarding the need to become involved in a viable reclaim program.”

Arkema’s Conlan is also predicting an uptick. “As the EPA has anticipated, we have just recently started to see an increase in reclaim coming back with the increasing price of R-22.” Said Beringer, “With the phaseout of HCFCs, the amount returned should increase as the price of used gas continues to rise. The very rapid appreciation in new product pricing may have led to the illegal practice of filtering used product and introducing it into the system of a different owner.” Ken Logan, president of A-Gas U.S. Holdings Inc., agrees, stating that “Currently the decreasing availability of virgin product is starting to make a difference. Over time the gap will widen further and the two will become inversely proportional.”

The HFC Factor

Also entering the equation is the industry’s focus on the use of HFC refrigerants as retrofits into systems originally designed for R-22. Owners of large amounts of equipment can move recovered R-22 around to not-yet-retrofitted systems and may or may not look at the reclamation option.

Honeywell’s Foutz said, “Retrofit HFC refrigerants have been available for several years. To date, the availability of the retrofit HFC refrigerants has not stimulated significant growth in R-22 reclamation. As R-22 supplies tighten, the economic incentive should stimulate retrofits to HFC refrigerants and stimulate R-22 reclamation growth.”

ICOR’s McKinney looks at the HFC retrofit from a historical perspective. “If given the opportunity, equipment owners will squeeze the most life out of their systems as possible. It was R-12-alternative HCFC refrigerants that played the most significant role in closing the supply/demand gap during the CFC phase out. Based upon the tremendous market shift in the last few months to HFC alternatives, history is set to repeat itself.”

He noted, “In the near future the R-22 supply — virgin and reclaimed — will be set aside for critical applications where alternative refrigerants are not suitable, such as flooded chillers and systems that have highly sophisticated refrigerant-specific controls.”

For A-Gas’s Logan, this can be iffy. “Keep in mind, retrofitting a system to a refrigerant it wasn’t initially designed for normally involves compromises and not everything is capable of retrofit. The industry itself will decide what can and cannot be retrofitted successfully. Retrofit activity will help conserve supplies of reclaimed R-22 overall.”

Jump Start

What will jump start the sector?

DuPont’s Goodge said, “It is a matter of supply-demand dynamics. If R-22 supply is limited, or the price increases dramatically, there is added incentive to manage the R-22 asset. A major element of a refrigerant management plan is extracting value from the installed R-22. Options include using recovered R-22 to do one or more of the following: gain access to lower-cost R-22 to continue to service equipment that remains on R-22, lowering the cost to retrofit existing equipment to an alternative HFC refrigerant, and/or reducing equipment replacement costs by extending the life of R-22 equipment by using either reclaimed R-22 or an HFC alternative.”

Airgas’s Beringer said it is a matter of economics, “People do not waste what is valuable. If the EPA had more enforcement, and made people accountable for their used product, then the culture would change. Higher pricing should help.”

As will awareness, said Consolidated’s Sweetman. “We believe that there is sufficient interest within the cooling and refrigeration industry to support increased reclamation. Companies that, for years, have been ‘kicking the can down the road’ or ‘dragging their butts’ are really starting to get on the ball. These contractors that have been conducting business as usual are finally reaching out to us for a more viable reclaim option.”

The Future of HFCs in Montreal Protocol

My Peter Powell

April 8, 2013

It’s easy to argue that no single development has impacted the HVACR industry as much as the Montreal Protocol. The international treaty, which was signed 25 years ago, ultimately phased out CFC and HCFC production; introduced refrigerant recovery, recycling, and reclamation; and, essentially, enveloped the HVACR industry under the power of the U.S. Environmental Protection Agency (EPA), which now dictates certifications and penalties related to the use and handling of refrigerants.

More than two decades later, the worldwide contract is still strongly impacting many sectors of the HVACR industry, including the decisions of contractors and service technicians. Ongoing discussions are currently underway, examining ways to incorporate HFCs into the protocol in order to phase down their use due to relatively high global warming potential (GWP). And while no changes are expected in the foreseeable future, these continuing conversations, and the potential developments pending, have surely caught the attention of those across the industry.

Good News

But first, the good news: The protocol was designed to protect the ozone layer by phasing out the production of substances found to be responsible for ozone depletion, those having ozone depleting potential (ODP).
And, it appears to be working.

“The Montreal Protocol is widely recognized for being very effective in reducing ozone depleting substances including CFCs and HCFCs,” said Robert Wilkins, vice president of public affairs, Danfoss. “Although we do not expect atmospheric chlorine to return to pre-1980 levels until about 2050, it has peaked and has been trending downward for several years.”

The Emergence of HFCs

With the HVACR industry forced to turn away from CFCs and HCFCs, it has moved on to HFCs, which include no ODP. However, many HFCs carried a high GWP due to their abilities to trap infrared radiations in the atmosphere, which does contribute to the greenhouse effect.

The latest efforts to revise the Montreal Protocol include rating gases based on GWP, as well as ODP.
Rajan Rajendran, vice president of engineering services and sustainability for Emerson Climate Technologies, noted, “The U.S., Canada, and Mexico have proposed an amendment to the Montreal Protocol to address global warming with a phase down of HFCs. This effort has been in place for a few years now. While there are 107 other countries supporting it, there are other, more developing countries like India, China, and Brazil who oppose. One barrier that is often mentioned is that the Montreal Protocol has historically had a very clear mission of addressing ozone depletion, but climate change is outside of its charter.”

Danfoss’ Wilkins added, “The EPA and the Department of State jointly held a stakeholders meeting in Washington on Feb. 5 with American industry leaders and others to discuss possible steps forward. With industry representatives expressing support for a well-planned orderly global HFC phase down on a GWP-weighted basis, it is likely the North American proposal will be resubmitted in 2013 for consideration at this year’s annual meeting.”

But what happens after that is uncertain, although many expect minimal action for a few subsequent years.
Mack McFarland, environmental fellow, DuPont Chemicals & Fluoroproducts, said, “The proposed amendment to the Montreal Protocol has not yet been endorsed by all of the developing countries. Amendments are adopted by consensus. Discussions continue with more and more countries voicing their support each year. I think the industry views the predictable process under the Montreal Protocol as preferable to country-by-country command and control regimes.”

Rajendran agreed. “While there are efforts to make some changes in the protocol, I don’t believe we’ll see any changes in the next few years.”

Europe and the US

European leaders are conversationally discussing HFC regulations based on GWP.

According to the website R-744.com, “The debate did advance, with countries discussing HFC amendment proposals in an informal setting, as well as requesting more information on the availability of environmentally sound alternatives to ozone depleting substances.”

R-744.com noted that this debate has spanned four years, without resolution. In his second inaugural address President Barack Obama said, “We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.” He did not specify any specific proposals during this speech.

A Feb. 12 report from the White House, titled, “The President’s Plan for a Strong Middle Class and a Strong America,” revived calls for more reliance on solar and wind energy generation. The only reference to climate change was the statement, “The president has directed his cabinet to identify executive actions from across the administration to help reduce pollution, prepare our cities and nation for the worsening effects of climate change, and accelerate the transition to more sustainable sources of energy.”

But most do not see this as an omen for unilateral action. For one, a divided Congress seems unlikely to act on potentially costly initiatives. And many in the industry see the EPA wanting to work in the framework of a global consensus.

At the same time, Rajendran did suggest, “The HVACR industry in the U.S. should be watching the emerging U.S. state government regulations out of the West and Northeast as well as potential U.S. government actions and regulations on greenhouse gasses.”

DuPont’s McFarland said, “There are a broad range of global activities under way to address greenhouse gas emissions, such as the U.S. CAFE standard for lightweight motor vehicles, renewable fuels, electricity programs in various countries, and cap-and-trade pilots in China. We anticipate that absent of a global agreement such as the Montreal Protocol, the U.S. government will seek ways to reduce HFC emissions under its current authority.”

But, in the context of a global perspective, Wilkins said progress may occur slowly. “Any changes to the Montreal Protocol would take a few years to enact. If India and China could be persuaded to support an HFC phase down, leading to a global consensus, the Montreal Protocol would then undergo negotiations to finalize the amendment and provide specific targets and timetables for phasing down HFCs globally. The amendment would then need to be ratified country by country. In the U.S., that would likely require action by the Senate. Once approved, each country could begin its own process for phasing down HFCs — similar to the phase down of CFCs and HCFCs.”

SIDEBAR: A No-Go for Kyoto

If changes to the Montreal Protocol are slow starters in regards to any additional impact on HVACR contractors, the Kyoto Protocol is a non-starter. Kyoto was to be the document to obligate countries, starting in 2005, to reduce greenhouse gas emissions (GHG). Many countries signed and ratified it. The U.S. signed it, but failed to ratify it and Canada withdrew from it in 2011.

Even then, many ratifiers had problems reducing GHG emissions to promised levels. However, more than 100 nations have pledged support behind the regulation of GHG emissions through the Montreal Protocol, and a growing number of countries are ready to join on, if a draft is ever presented.

Mack McFarland, environmental fellow, DuPont Chemicals & Fluoroproducts, said, “While there are no discussions under the Kyoto Protocol specific to the HVACR industry, there are active discussions under the Montreal Protocol.”

Robert Wilkins, vice president of public affairs, Danfoss, acknowledged that climate change is emerging as an important issue for the Obama administration. “Since the U.S. never ratified the Kyoto Protocol, and nothing has developed regarding refrigerants, there isn’t likely to be any impact on the HVACR industry.”
Rajan Rajendran, vice president of engineering services and sustainability for Emerson Climate Technologies, said climate-change regulations could still surface in the U.S.

“From the Kyoto Protocol point of view, which is focused on climate change, the HVACR industry in the U.S. should be watching the emerging U.S. state government regulations on greenhouse gases.”

EPA Finalizes R-22 Allocations for 2012-2014

By Charlie McCrudden | April 4, 2013 | Leave a Comment

On April 3, the U.S. EPA published in the Federal Register the final rule adjusting the allocation of HCFCs (including R-22 refrigerants) for the years 2012-2014 (2013 Final Adjustment Rule).

According to the Final Adjustment Rule, R-22 allowances for 2013 will rise by about 13% relative to 2012, and decrease by 20% in 2014 relative to 2012. The allocations for the years 2015-2019 will be set in a subsequent rulemaking. These allocations became effective on April 3, 2013.
See the chart below (click to enlarge).

Contractors may want to contact their wholesalers or gas distributors to inquire about any changes in pricing or sales policies in light of the 2013 Final Adjustment Rule. Despite the unexpected increase in the allocations for 2013, the market remains volatile and prices for R-22 may not respond to the increased supply.

Background
The U.S. EPA controls the production and use of HCFCs, including the refrigerant R-22, through a cap and trade program. The amount of virgin R-22 that can be produced in a given year is set by annual allocations. The production and use of HCFCs is slowly being phased out in the United States, because these chemicals are known to damage the ozone layer when released into the atmosphere.

In 2011 the EPA was ordered to reopen the 2009 Allocation Rule that set the allocations for the years 2010-2014. The order came from the U.S. Court of Appeals for the District of Columbia Circuit in a lawsuit filed by two gas producers who charged that the EPA had failed to recognize their legally traded allocations.
In August 2011, the EPA proposed to adjust the R-22 allocations in the three remaining years of the 2009 Allocation Rule (2012-2014).

Based on consultation with industry stakeholders, the EPA determined there was an oversupply of virgin R-22 in the marketplace, evident with low demand, increased reuse of R-22, and low wholesale prices. In 2010, R-22 producers only utilized 86% of their allocations. A trade organization representing the manufacturers and importers of R-22 supported these claims, and advocated for a 20% reduction in allocations for 2012-2014.

Since 2012 refrigerant producers and importers have been operating with only temporary, 12 month authority through “No Action Assurance” letters from the EPA. Without a finalized Adjustment Rule, and without the No Action Assurance letters, virgin R-22 could not be legally produced or imported into the United States. The No Action Assurance letter from the EPA advised allocations would be less than the 2009 Allocation Rule.

The 2013 Final Adjustment Rule sets the allocations for the years 2012 (retroactively), 2013, and 2014.
In 2013, the total amount of R-22 allocated to all producers and importers is about 62.8 million pounds, compared with about 55.4 million pounds allocated for 2012. In 2014, the total allocation of R-22 will drop to 51 million pounds.

Contact: Jacqlyn Ucinski

This webinar will provide a technical overview of the many different R-22 retrofits available today and how to choose the right retrofit solution. Also a brief discussion of R-22 market dynamics will be covered. A summary of what products are offered and for which specific application each one is best suited will be included along with selection criteria. The tradeoffs and compromises that occur when using retrofit refrigerants in a system specifically designed for R-22 will also be addressed. After attending this seminar, you will: Understand the R-22 EPA activity and market response Learn why some refrigerants may be better than others for your retrofit applications Understand why there are no real “drop-in” retrofits but may still have hassle-free options Become familiar with the most important criteria to consider when selecting a new R-22 alternative refrigerant

The EPA Cracks Down on Illegal R-22 Importation and Sale

The Alliance for Responsible Atmospheric Policy, an industry coalition, said in November 2012 the United States government successfully concluded 11 criminal and civil cases related to HCFC-22 refrigerant smuggling over the last two years. The alliance said that individuals and companies were found guilty of various crimes related to the illegal importation or sale of over 3.3 million pounds of R-22, fined over $1.5 million, required to forfeit proceeds of almost $2.7 million, and received jail and probation amounting to over 26 years.


“The U.S. government is very serious about tracking down those who illegally import or sell HCFC-22. Anyone devising illegal schemes to import or sell this refrigerant is on notice that the U.S. will arrest and convict you,” said Dave Stirpe, alliance executive director.

Only Buy Legal R-22

Stirpe went on to say that the alliance cautions industry and the public to be certain that their R-22 refrigerant purchases are legal, and to report any offers to buy illegally imported refrigerants to the U.S. Environmental Protection Agency (EPA). R-22 refrigerant may be legally produced domestically and imported into the U.S. provided that EPA-issued quota allowances are expended. Anyone importing HCFCs without legal allowances is in violation of federal law. R-22 is generally used to service and maintain existing commercial air conditioning and refrigeration equipment. Newly produced equipment generally relies on HFCs and other refrigerants.

"Purchasers of the illegal refrigerant are at risk,” Stirpe said. “The government may confiscate any illegally imported refrigerant, even if it has been passed down through the marketplace, and it may prosecute purchasers who knowingly buy illegal material. Consumers should also be wary of the refrigerant since some of the imported material has been found to be of poor quality, or it could be counterfeit.”

He went on to say that purchasers of imported R-22 should verify that their importer is an authorized EPA baseline consumption allowance holder, or was involved in a subsequent legal trade of consumption allowances. An EPA list of baseline consumption allowance holders can be found at www.epa.gov/ozone/title6/allowance.html.

Some other points made by the alliance about importation and purchase of R-22:

• The recipient of a trade can show a letter from EPA acknowledging the approval of the trade.

• Purchasers who question the legitimacy of an HCFC-22 importer should request a copy of the EPA approval letter from the seller.

• Importers of used HCFCs must follow EPA petition process requirements listed at www.epa.gov/ozone/title6/imports/usedclasstwo.html.

• Violations should be reported at www.epa.gov/tips/, and may be done so anonymously.

Beyond Familiar HFCs

DALLAS — While much of the buzz at the AHR Expo was on dwindling supplies of new HCFC-22, reclamation of that refrigerant, and use of alternative HFCs in retrofits, a number of conversations centered on alternatives beyond familiar HFCs. Even with the regulatory landscape unclear, the high global warming potential (GWP) of some HFCs was causing a stir on the show floor.

Low-GWP HFCs

While HFC-410A was firmly encamped as the refrigerant of choice for air conditioning in a large number of applications, its high GWP was turning attention in Dallas to use of HFC-32 as a stand-alone refrigerant. HFC-410A, which was introduced to the industry more than a decade ago as an alternative to R-22 in new equipment, carries a high GWP. R-32 has a much lower GWP (675 vs. 2088). This is a topic that has been in the industry for a number of years, since it first surfaced as a high-profile topic in 2010 at industry conferences hosted by Purdue University.

Danfoss furthered this notion at its AHR Expo booth, where it displayed its SG scroll compressor with the signage: “Get ready for Green Solutions with R-32.”

HFOs on Display

HFO refrigerants are widely recognized as the next generation of refrigerants. The alternative garnered its fair share of attention at the expo as well.

On the show floor, Honeywell was issuing a statement about its HFO refrigerant 1234ze which it markets as Solstice L-41. The manufacturer compared its refrigerant, stating that their refrigerant offers “significant advantages over another (R-410A) alternative, R-32, which has a higher GWP and limitations related to high-discharge temperatures, which can affect performance and durability in hot climates, and may also require new lubricants.”

Honeywell boasted that Solstice L-41 offers a 75 percent reduction in GWP compared to R-410A and is intended to replace R-410A in residential and light commercial air conditioning and heat pump applications. In addition to its lower GWP, Solstice L-41 offers excellent energy efficiency, is cost effective, and can be used in existing equipment designs with minimal changes.

“Honeywell has been working closely with leading equipment manufacturers to optimize Solstice L-41 to meet the demanding requirements of both stationary air conditioning and heat pump applications across a broad range of operating conditions,” said Tom Morris, director of commercial development for Honeywell Fluorine Products. “Solstice L-41 will allow these manufacturers to offer more environmentally friendly air conditioning and heat pump systems to help address climate change.”

Solstice L-41 is based on Honeywell’s HFO-1234ze technology, which was “first introduced in 2008 and has since been proven and commercialized for chillers, insulating-foam, and aerosol applications. A new HFO-1234ze manufacturing plant is currently under construction to meet the needs of equipment manufacturers.”

Even with its involvement with R-32 in some applications, Danfoss was waving the HFO flag. The company used a press conference to announce its involvement with HFO-1234ze in its Turbocor line and the commercialization of TG310 compressors, which were released as a developmental prototype in early 2012. The company said the compressors “utilize the ultra-low GWP, zero ozone depletion potential (ODP) refrigerant HFO-1234ze.”

Safety First

As the HFO sector evolves it is becoming clear that there are HFOs with A1 (nonflammable) safety ratings and those that have A2L (slightly flammable) safety ratings. A1s generally carry higher GWPs than A2Ls. This means the sector will have to sort itself out. If regulations set especially low GWP maximums, only A2Ls would be allowed to establish a beachhead; which would require UL certification, as well as building code modifications, for the installation of such equipment in certain portions of the country.

One HFO topic that appears to be sorting itself out is in the automotive sector. After automaker Daimler expressed some safety concerns over the use of HFO-1234yf in vehicle air conditioners last fall, General Motors issued a statement at the time of the expo pledging to move ahead with the use of that HFO in its vehicles — saying that in all its testing, the refrigerant proved safe and effective.

HCs and CO₂

A number of manufacturers showed equipment for natural refrigerants such as HCs and especially CO₂ at the expo.

During a Danfoss press briefing, Scott Martin, director of sustainable technologies, Hill Phoenix, spoke about CO₂ developments that his company has been doing in conjunction with Danfoss. He said that his company’s systems that utilize CO₂ technology offer several distinct advantages over traditional DX-refrigeration systems. “These CO₂ sub-critical systems deliver superior refrigeration performance with enhanced sustainability, reduced refrigerant-charge requirements, and greatly reduced refrigerant-leak rates. Simply, they are the most energy-efficient and environmentally friendly refrigeration systems available in the industry today.”

He also noted advances in CO₂ in transcritical-application use of which are growing in North America. That was reinforced on the show floor at the Bitzer booth where a transcritical-CO₂ compressor was displayed.

The editors of the European-based online publication R744.com also walked the floor at AHR and provided a viewpoint for its global readership regarding the future direction of CO₂ use in the United States.

“The pure number of booths displaying CO₂ refrigerant components and systems has not significantly increased from last year’s trade show. However, the showcase of breakthrough innovations, prototypes, and optimized product lines in R-744 (CO₂) compressors, heat pumps, or air conditioners, as well as commercialization announcements expected for the next 12 months are all solid indicators that the U.S. market is getting serious about R-744.”

Climate Change Rejoins Agenda

So just when we thought regulatory actions related to the environment were pretty mute, given not much traction in Washington mainly due to a sluggish economy, along comes, of all people, the president of the United States.


Barack Obama was barely into his second inaugural address when he said, “We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.” He did call it climate change instead of global warming, since the former is the more popular catch phrase, especially when temperatures are below average. When temps are above average, the buzz phrase goes back to global warming.

He even had a dig for those few who still doubt what used to be called global warming. “Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.”

It has never been clear to me how much the HVACR industry contributes to “devastating impacts,” and certainly the president’s examples can’t seem to be directly blamed on HVACR.

Next came the plug for alternative energy sources such as wind and solar. “The path toward sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition; we must lead it.”

Here, the idea is that wind and solar will be taking us off the electric grid, which powers nearly all our HVACR needs. It is just that when there is no wind or no sun, the grid has to be relied on — and nobody has really come up with a cost-effective, energy-efficient option.

And speaking of money, the inaugural speech did not go into specific dollars and cents when it comes to addressing climate change and embracing new energy options. It was more like we can do it all. He said, “We cannot cede to other nations the technology that will power new jobs and new industries — we must claim
its promise.”

This is not a political column so I won’t comment on how the president intends for the United States to become a leader in taking on climate change and getting more interest in alternative energy sources and what it will cost. He did make a brief reference to dealing with the cost issue in the context of healthcare and the deficit. “We must make the hard choices to reduce the cost of health care and the size of our deficit. But we reject the belief that America must choose between caring for the generation that built this country and investing in the generation that will build its future.”

The point here is that he is trying to put climate change back on the front-burner/high-priority list during his last term in office. If climate change includes global warming issues, then many HFC refrigerants come back into the political/regulatory arena because of their perceived high GWP.

That issue never goes into the background in Europe. Even now, the European Commission, which does a lot of the regulatory legwork for the European Union, which is made up of 27 countries, is putting pressure on some sort of phase-down of HFC use in Europe, and, in cases where natural refrigerant options can be used, a phaseout of HFCs. There is still a way to go in Europe in terms of anything taking hold and manufacturer organizations over there are continuing to draw attention to the potentially higher total energy costs of using alternative refrigerants.

But should that effort in Europe gain some momentum, it is sure to cross over the Atlantic just as the phaseout of CFCs and then HCFCs started in Europe and then came to North America. The question then becomes, if that momentum does reach the U.S. within the next four years, how much will President Obama’s renewed attention on climate change in his speech move things forward?
