This paper first analyzes the piston refrigeration compressor test system built by the second refrigerant method. And bulit the simulation test system model of piston refrigeration compressor by Matlab/Simulink platform. The results show that the optimized simulation test system is in good agreement with the physical test data, which proves that the simulation test system of piston refrigeration compressor is reasonable and reliable. It provides a reliable simulation test platform for the subsequent design and performance prediction of refrigeration compressor, and lays a good foundation for the in-depth study of refrigeration compressor performance and the establishment of a more accurate simulation system.
