Steady-State Modeling of the Refrigeration Unit for a Marine Refrigerated Container

摘要

The mathematical models of compressor, evaporator and condenser in a refrigerated container's refrigeration unit were established, which were used to form the whole system model for steady-state simulation according to the coupling relationship among them. The fullload performance of the refrigeration system was firstly deployed using the system model programmed in the MATLAB software. And the experimental performance tests were secondly carried out using a marine refrigerated container test rig. The errors between simulation results and experimental results are within 10%. Therefore the model has good simulation accuracy and could be used for the future energy-saving analysis of the marine refrigerated container.
