Abstract:

A refrigeration system and method of operating a refrigeration system having a loop comprising a compressor, a condenser, an expansion device and an evaporator, with the compressor compressing a refrigerant gas thereby heating the gas to a hot gas and the condenser removing heat from the hot gas thereby transforming the hot gas to a liquid refrigerant. The compressor has an inlet receiving gas from the evaporator and an outlet supplying hot gas to the condenser. The expansion device expands the liquid refrigerant from the condenser to a liquid-gas in the evaporator thereby absorbing heat. A heat exchanger transfers heat from the liquid refrigerant supplied to the expansion device. This increases energy density of the refrigerant.
