China is the largest producer and consumer of hydrochlorofluorocarbons(HCFCs),and the production of HCFC-22 accounts for more than 80%of all HCFCs.This paper concentrates on the residential air-conditioner industry and analyzes the environmental benefits of accelerating the phase-out of HCFC-22 in China.According to the comparison of the baseline and phase-out scenarios of HCFC-22,the findings show that using HC-290(propane) as a refrigerant alternative will directly reduce the greenhouse effect,and indirectly reduce the emission of greenhouse gases due to a reduction in the electricity consumption.The comparison of two scenarios of HC-290 and HFC-410A refrigerant alternatives shows that the use of HC-290 refrigerant will produce significantly higher environmental benefits than the HFC-410A refrigerant.
