摘要

通过对定速与转速可控房间空调器能效标准的分析，发现两类房间空调器的能效划分标准、划分等级以及制冷运行室外温度发生时间均有不同的规定。因此对国内市场上的定速房间空调器制冷量和制冷循环的能效比（EER）、转速可控房间空调器制冷量和制冷季节能效比（SEER）、以及定速房间空调器与转速可控房间空调器的能效等级现状等方面进行了调研统计。利用热力学完善度对两类房间空调器能效等级进行计算，发现2008版转速可控房间空气调节器的能效等级的热力学完善度偏低，根据热力学完善度相一致的原则，提出转速可控房间空调器新的能效标准等级的建议。

Abstract

According to analysis on the energy efficiency standards of the constant speed room air conditioner and the variable speed type

differences between the two kinds of air conditioners exist in division standard

grades of energy efficiency and outdoor temperature starting refrigeration. Therefore

a survey was made about cooling capacity and EER as well as energy efficiency grades of the constant and variable speed room air conditioners. The thermodynamic perfectibility of the two types of room air conditioners was calculated for the performance evaluation. The calculation results show that energy efficiency standard of variable speed room air conditioners in 2008 is lower than that of constant room air conditioners. A new energy efficiency standard of the variable speed air conditioner is suggested in accordance with the consistent thermodynamic perfectibility.
