Research on Simulation of Marine Refrigeration System Based on Simulink

A simulation based on simulink was set up to investigate the performance of marine refrigeration system. For the simulator focused on the operation and management, so the steady state simulation algorithm is to be used to build simulator of the whole system, it gives consideration to both efficiency and precision of simulation calculation, real-time of operation and management is increased. Compressor thermal model is simple, most of that use steady-state model with no iterative computation. Due to the need of teaching and simulation operation, we use lumped parameter method and partition method to establish mathematical model of Condenser, evaporator, expansion valve, evaporator pressure regulator, cold storage and other parts. True-time operation and the appraisal function has developed. The simulation result accorded well with the experiment result. This model precision is high and timely. It was acceptable used in the ships refrigeration system's operation.
