A semi-empirical method for modelling a reciprocating compressor in refrigeration systems.

Author(s) : POPOVIC P., SHAPIRO H. N.

Summary

The model is based on thermodynamics principles and a large data base. The purpose of the model is to reduce the amount of data required to completely characterize compressor performance using alternative refrigerants. Two compressor performance parameters were defined. An effective pressure drop accounts for mass flow losses in the compressor, while numerically determined functional dependence of the heat transfer loss coefficient is related to compressor energy losses. These parameters depict compressor operation with reasonable accuracy. The model predicted mass flow rates and required compressor power for all data points within 10% of relative error.
