Popis: The mathematical models of the storage refrigeration system of cold-water screw unit has been established.The operating condition of the unit and the system which working at partial load has been simulated,with different return water temperature of condenser.The influence from the return water temperature of condenser on the COP of the unit and system on the condition of different capacity of compressor has been analyzed, when the evaporation temperature is -10°C.The fact that it’s better to use start and stop operation with upload and download step by step rather than operate on the condition of low capacity of compressor, and that it’s beneficial for systemic energy conservation to use the variable frequency pump have been concluded.
