转速可控型房间空调器用压缩机能效评价方法研究及应用

Analysis and Application of Evaluation Method on Compressors for Variable Speed Room Air Conditioners

随着全球环境保护意识的加强,家用空调能耗水平不断增高,房间空调器能效评价方法已从单工况向全年运行效率(APF)转变。压缩机作为空调器中的主要耗能部件,其能效评价方法也要随之变化。这里提出了变速压缩机全年综合能效比指标--COAP来衡量压缩机在全年变工况条件下的运行效率,此指标综合考虑了变速压缩机全年运行的能效情况,能客观反映压缩机在不同气候条件下实际运行效率。为简化测试COAP,给出了COAP基准工况及各工况权重,讨论了压缩机效率曲线对COAP的影响,最后通过举例说明如何利用COAP进行压缩机选型及设计优化。

The efficiency requirement of room air conditioner （RAC） has became stricter and stricter with the development of global environment consciousness. The efficiency evaluation method of RAC has been updated from single working condition to aunnal performance factor （APF） with multiple working condition. Performance evaluation method of compressors must be changed accordingly which account for main energy consumption of RAC. Compressor efficiency of annual performance （COAP） is proposed to evaluate the efficiency level of inverter compressor which is applied in variable speed RAC with multiple working conditions. Actual operation efficiency can be indicated by COAP because inverter compressor performance is considered according to COAP. In order to simplify test procedure of COAP, standard test conditions and its weight are generated .Then the effect of efficiency curve of inverter compressor on COAP is discussed. Finally examples with this method are illustrated for compressor matching and design optimization.
