中国房间空调器行业淘汰HCFC-22的环境效益分析

中国是当前最大的HCFCs(含氢氟氯烃类物质)年生产和消费国家,而其中HCFC-22的生产量约占全部HCFCs的80%。2007年国际社会决定加速淘汰HCFCs,这将带来巨大的环境效益。为此,选择房间空调器行业对我国加速淘汰HCFC-22的环境效益进行了分析。通过淘汰情景和基线情景对比得出,采用HC-290(丙烷)替代制冷剂既可以直接实现温室气体减排,又可以节电从而间接减少温室气体排放。比较HFC-410A和HC-290两种替代淘汰情景,后者的环境效益显著高于前者。

Environmental Benefits from Phasing Out HCFC-22 in Residential Air- Conditioner Industry in China

China is the largest country of HCFCs (hydrochlorofluorocarbons) production and consumption, and the production of HCFC-22 (Chlorodifluoromethane) accounts for more than 80% of all HCFCs. In 2007, the international community decided to speed up the elimination of HCFCs, China's implementation will bring great benefits to the global environment. 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, it's found that using HC-290 (propane) as a refrigerant alternative will directly reduce the greenhouse effect, and indirectly reduce the emission of greenhouse gas due to the 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 use of HFC-410A refrigerant.
