Environmental considerations are reducing the number of chemicals that can be used as refrigerants. The HFCs were introduced to replace ozone depleting CFCs and HCFCs, but they are greenhouse gases and are subject to use restrictions in some countries. As a result the industry is evaluating chemicals with very low global warming potential. Some of these chemicals are mildly flammable and have been assigned to a new flammability safety classification, 2L, in ASHRAE Standard 34. This seminar provides information on the changes to standards that specify requirements for the use of 2L flammable refrigerants.
