Résumé

The compressor model used in the dynamic simulation of refrigeration system should not only be applicable in the case of the state of the sucked refrigerant varies in a wide range of vapor to two-phase, and also be quick enough in predicting the major dynamic characteristics of the compressor. In order to meet these requirements, a quasi-dynamic hermetic compressor model covering the suction state from vapor to two-phase was presented in this paper. According to its thermodynamic process, the compressor model includes a dynamic model for the mixing process of refrigerant inside compressor and sucked two-phase or vapor refrigerant, a dynamic model for the compressor shell heat transfer model, and a steady state model for the polytropic compression. The compressor model overcomes the flaw of unreasonable mass flow of the existing models caused by neglecting the mixing process of refrigerant inside a compressor. The maximum differences of steady state mass flow rate and input power of a hermetic compressor between the experimental data and the predicted results are less than 5%, while the deviations of the predicted transient mass flow rate and input power from the experimental data are within 10%.
