中文摘要：

对节能空调器在我国主要城市城镇住宅中应用的寿命周期能耗状况进行了定量分析，并分析了住户空调运行模式的差异对空调器寿命周期能耗的影响。研究结果表明，对于夏季气候炎热、经济发达的地区和空调能耗较高的住户，采用节能空调器的节能效果显著；但对于北方地区的许多住户和其他气候区空调能耗较低的住户，采用节能空调器会使空调器寿命周期能耗增加，同时使材料资源消耗增加，因此应针对不同的气候条件、不同经济发展水平和不同建筑类型，制定不同的空调器能效标准。

英文摘要：

Calculates the life cycle energy consumption of air conditioners in urban residential buildings in main cities in China. Analyses the influence of operating mode of air conditioners on the life cycle energy consumption. The results show that the energy saving effect of energy efficient air conditioners is significant for the households in southern tropic areas or the higher energy consumption households, but for some households in cold weather areas or the lower energy consumption households in other areas, the life cycle energy consumption of the air conditioners with one-level energy efficiency is higher than that of the air conditioners with five-level energy efficiency and energy efficient air conditioners consume more material resource. So it is necessary to set different EER standards of air conditioners for different weather areas, different economy level and different function buildings.
