That is interesting. And a bunch of BS. Force 100's of Thousands of conversions to an almost equally damaging gas, then obsolete and phase out the conversion gas systems. Sounds like the inmates are running the asylum. Thanks for posting. |

Lawrence - let me get this straight. The EU is now banning R-134a at a time when the U.S. has not only mandated it, but is "enhancing" its system use. Do I have this right? Jim S. |

I received the following Heat Transfer Service Newsletter. It's lengthy but interesting. Press Release from the Society of Automotive Engineers (SAE) Recent changes in European automotive A/C System refrigerants presented at SAE Alternate Refrigerant Symposium in Phoenix. Warrendale, PA, June 20, 2003 - When it comes to automotive environmental regulations, sometimes laws happen in Europe and eventually find their way across the Atlantic. One kind of emission produced by automobiles comes in the form of the refrigerants in automobile air conditioners, and the regulatory focus of the European community (EC) is once again on making a change. European Commission representative Dr. Matti Vainio will present an overview of the EC timetable for phasing out refrigerant R-134a at the SAE Alternate Refrigerant Symposium, July 15-17, 2003 at the Resort Suites Hotel in Scottsdale, Arizona. Dr. Vainio's presentation will take place Tuesday morning. Automotive engineers and suppliers of automotive air conditioning systems from around the world attend this 5th SAE event to share ideas and information about what has remained a hot technology area of automotive design and government regulatory focus. The Europeans are moving to phase out R-134a as a refrigerant because it is on the Kyoto Agreement "hit list" of gases thought to contribute to global warming. R-134a itself was mandated in the U.S. as a replacement for CFC-12, commonly known by its trade name "Freon" due to CFC-12's depletion of atmospheric ozone. Most of the European nations signed the Kyoto Protocol that calls for cutbacks in carbon dioxide emissions and the release of other global warming gases. Following Dr. Vainio to the podium is Dr. Stephen Andersen of the U.S. Environmental Protection Agency, who will present "A Voluntary Agreement to Enhance HFC-134a Systems Worldwide." Dr. Andersen's talk will cover the benefits of producing enhanced HFC-134a systems. Ward Atkinson, Chairman of the SAE Interior Climate Control Standards Committee stated "Alternate refrigerant mobile air conditioning systems must provide at least the same level of consumer acceptance for performance and reliability as production HFC-134a systems. One of industry activities is the SAE industry and government sponsored Alternate Refrigerant Cooperative Research Program providing a directly comparative engineering evaluation of existing HFC-134a and other refrigerant technologies." The replacement most often mentioned is a CO2 system having an advantage of no net increase in global warming gases. Another alternative refrigerant being considered in Europe is HFC-152, which is less harmful to the ozone layer but is somewhat flammable, having a lower global warming affect as compared with HFC-134a. The industry is currently evaluating these alternate refrigerant systems for performance, efficiency and their production feasibility as a replacement for HFC-134a systems. During the SAE Alternate Refrigerant Symposium there will be technical presentations and demonstration vehicles using CO2, HFC-152a and secondary loop systems.
