摘要

When CFC12 it substituted by use of HFCl62a/HCFC22 mixture, the performances of refrigerator compressor including consumed power, refrigerating capacity, volume efficiency, will be variable from using CFC12. So, tie compressor should he redesigned or improved. In this paper, firstly, the thermoproperties of HFC152a/HCFC22 were precisely calculated by using PR equation of state combined with mixture rule and thermodynamic relations. The data base of thermoproperties was built to be called when predicting performance of compressor. Secondly, the refrigerator compressor was predicted theoretically and verified experimentally. The mathematical model was built according to energy equation, mass flow equation, mass equilibrium equation and heat transfer equation. The software package of compressor performance simulation was provided depending upon finite unit method, and some characteristics of compressor, those are valve behaviour, indicated power and refrigerating capacity, were predicted by use of this package. Based on the model, the satisfied results were gotten from the verified experiment.
