Abstract
A refrigeration system comprises a compressor for increasing a temperature and a pressure of a refrigerant vapor, a condenser fluidly coupled to the compressor for condensing the refrigerant vapor, an expansion device for decreasing the temperature and pressure of a refrigerant liquid, and an evaporator fluidly coupled to the expansion device for evaporating the refrigerant liquid by transferring thermal energy between the refrigerant liquid and a second fluid. The refrigeration system also comprises a heat exchanger having a first flow path fluidly coupled to the compressor and the evaporator and a second flow path fluidly coupled to the condenser and the expansion valve. The heat exchanger is adapted to superheat the refrigerant vapor in the first flow path and subcool the refrigerant liquid in the second flow path by transferring thermal energy between the refrigerant in the first and second flow paths.
