摘　　要：对53台来自在不同温区、不同品牌的、不同制冷量、使用了5年及以上的在用房间空气调节器能效进行了测试分析,结果表明除不同品牌的产品能效衰减率差异较大外,使用温区、使用年限、产品制冷量对空调能效衰减率的影响不大。使用了5年或更长时间的家用空调器能效水平远低于当前标准规定的能效限定值,普遍低20%~30%,最高可低54%。为分析加速淘汰在用空调器的节能减排潜力,以2008年中国在用空调器的保有量进行估算,即使以当前最低能效水平的空调器进行替代,一年仅制冷季节节电量也高达2147亿度电,二氧化碳减排量达2.14亿吨。如果更换为能效等级更高的空调或变频空调,节能减排的潜力更大。53 sets of on-duty room air conditioners coming from different temperature areas, made from different manufactures, having different cooling capacities and having been used no less than 5 years were tested and ana-lyzed.Results show that except for the decay rate of energy efficiency of products with different brands various signifi-cantly, the effect of service temperature areas, on-duty duration and cooling capacity on the decay rate of energy ef-ficiency is negligible.The energy efficiency of domestic air conditioners served for more than 5 years is much less than the minimum allowable energy efficiency values stipulated in current standards with majority 20%~30%lower, some even 54%lower.In order to analyze the potential of energy conservation and carbon dioxide reduction caused by accel-erating eliminating the on-duty domestic air conditioners, the market share of on-duty air conditioners in China in 2008 was taken for case study.Results indicate that even if the on-duty air conditioners were replaced by new air con-ditioners of minimum allowable energy efficiency, it will save 214.7 billion kWh power and reduce carbon dioxide e-mission 214.7 million ton every cooling season.If they are replaced by higher energy efficiency air conditioners or vari-able-speed ones, the potential of energy conservation and carbon dioxide reduction will be bigger.
