HTML _ 93-382 - CFC Phaseout: Future Problem for Air Conditioning Equipment?
1-Apr-1993; David E. Gushee; 11 p.

Abstract: In response to both domestic law (the Clean Air Act as amended) and international agreement (The Montreal Protocol on Substances that Deplete the Ozone Layer), the United States is well down the road toward complete phase-out by 1996 of production of chlorofluorocarbons (CFCs) and other ozone depleting substances. For most uses, the phaseout will probably not cause severe side effects. For air conditioning and refrigeration equipment, however, the jury is still out; there is a large inventory of CFC-using equipment; shortages of phased-out refrigerants in 1996 and thereafter could cause sharp increases in refrigerant prices, problems in servicing equipment dependent on the phased-out refrigerants, and shortages of equipment able to use the new generation of refrigerants. In response to these possible difficulties, the Environmental Protection Agency (EPA), the Alliance for Responsible CFC Policy, the Air Conditioning and Refrigeration Institute (ARI), the Mobile Air Conditioning Society (MACS), and others have initiated programs designed to foster recovery of CFC refrigerants, reduce refrigerant leakage, and stimulate early conversion of CFC-using equipment to substitute refrigerants such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). Despite these programs, the rates of retrofit, on the one hand, and recovery and ¨banking¨ of CFCs, on the other hand, as envisioned today, do not appear to be great enough to avoid significant transition problems. [read report]
