Summary

The efficiency requirement of room air conditioner (RAC) has become increasingly stringent with the development of global environmental awareness. The efficiency evaluation method of the RAC has been updated from single working conditions to annual performance factors (APF) with multiple working conditions. Performance evaluation methods of compressors must be changed accordingly, which accounts for the main energy consumption of the RAC. Compressor efficiency of annual performance (COAP) is proposed to evaluate the efficiency level of the inverter compressor which is applied in a 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 the test procedure of COAP, standard test conditions and weighting are generated .Then the effect of the efficiency curve of inverter compressor on COAP is discussed. Finally examples with this method are illustrated for compressor matching and design optimization.
