摘要:

目前我国变频空调器能效等级均采用全年性能系数(APF)作为评价指标。基于现有变频空调器运行范围宽、调节范围广的特点,指出了现有APF计算方法存在的不足,在环境温度高于35 ℃时的近似计算方法不符合实际情况,并给出了改进建议。

Abstract:

China inverter air conditioner industry adopts annual performance factorAPF as energy efficiency evaluation index. Presents the problems of the calculation methods for APF of inverter air conditioners, due to the characteristics of wide operating range and adjustment range of inverter air conditioners. The calculation method does not match the actual situation when the environment temperature is higher than 35 ℃,and suggests the improvement opinions.
