Abstract

Based on the exergy analysis model and the data of an ASHPWH system,exergy analysis of the system was carried out,and the way was discussed to reduce exergy loss.The exergy efficiency of the system was 43.7%,and the exergy loss coefficient of the compressor was the largest in the system,accounting for 26.12%.then, the exergy loss coefficient of the expansion valve, the condenser and the evaporator account for 14.15%,9.82%and 6.21% respectively.The key components to improve the exergy efficiency were compressor and expansion valve,and the join control of electronic expansion valve and variable frequency compressor may be a feasible way to improve improve exergy efficiency.
