Abstract:
Objective To ensure the freezing quality of prepared frozen foods through the access of research on the effects of such influential factors as the refrigeration compressor, the quick-freeze temperature, freezing rate, energy conservation etc.Methods The application and performance of single-stage screw compressor and the double-stage screw compressor were compared in order to choose the proper product type.Results The double-stage screw compressor used in the R22 and R404A refrigeration systems had the obvious advantages of better refrigeration capacity, improved refrigeration efficiency and energy conservation, when evaporation tempera-ture was below-30℃.Conclusion The double-stage screw compressor had wide application in the naval refrigerated food supply chain for naval vessels.
