ABSTRACT:
A liquid refrigeration system for providing cooling operations, including an evaporator with its refrigerant outlet connected to a vapor/liquid separator so that refrigerant in the refrigerant conduits in the evaporator may undergo heat exchange in the form of a mixture of vapor and liquid. The compressor of the system outputs high pressure refrigerant vapor which passes through a specially designed condenser before being conveyed to a thermostatic expansion valve at the front end of the inlet of the evaporator. Low-pressure oil-rich liquid refrigerant separated by the vapor/liquid separator first passes through the condenser to become superheated vapor and it is then sent to the suction line of the compressor together with the saturated refrigerant vapor from the vapor/liquid separator. The expansion valve meters the flow rate of system refrigerant and has a temperature sensor which detects the superheat of the low pressure refrigerant vapor leaving the condenser.
