Automobile air conditioning: A case study of CFC replacements part II

Global warming impact (GW) of automobile air-conditioners using two refrigerants — a hydrocarbon blend and HFC-134a -were estimated and compared. The HFC-134a system showed a GW 20–90% greater than that of the hydrocarbon system. Volatile organic compounds (VOC) emissions of the air-conditioners were near to equal, in the basecase scenario slightly higher for HFC-134a, in some scenarios slightly higher for the hydrocarbon.
