The relationship between the refrigerating capacity of the compressor and the evaporating temperature and the condensing temperature, the refrigerating capacity decreases with the decrease of the evaporating temperature or the increase of the condensing temperature.

The refrigerating capacity of the evaporator is not only determined by the difference between the storage temperature and the evaporation temperature, that is, the heat transfer temperature difference, but also related to the outlet superheat degree (dry type) or the liquid level (full liquid type) of the refrigerant. When the storage temperature is constant, its refrigerating capacity increases as the evaporating temperature decreases.

Cold room condensers

The refrigerating capacity performance curve of the condenser can be seen. When the evaporating temperature or condensing temperature decreases, the refrigerating capacity decreases; in addition, when the cooling water quantity decreases and the cooling water temperature increases, the refrigerating capacity also decreases.
