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。
China is currently the largest producer and consumer country for HCFCs (hydrochlorofluorocarbons), of which HCFC-22 production accounts for about 80% of all HCFCs. In 2007, the international community decided to accelerate the phase-out of HCFCs, which will bring tremendous environmental benefits. To this end, the room air conditioner industry to choose our country to accelerate the phase-out of environmental benefits of HCFC-22 were analyzed. By comparing the phase-out scenario with the baseline scenario, it can be concluded that using HC-290 (propane) instead of refrigerant can directly reduce greenhouse gas emissions and save energy, thereby indirectly reducing greenhouse gas emissions. Compared with the two alternative phase-out scenarios of HFC-410A and HC-290, the latter has significantly higher environmental benefits than the former.
