Abstract
A transport refrigeration system of the type which holds a set point temperature by way of heating and cooling cycles. A compressor discharge temperature control circuit is provided which senses the temperature of the hot compressor discharge gas and controls a flow of liquid refrigerant directly into the compressor suction line responsive to the sensed temperature. The receiver of the system is provided with hot gaseous refrigerant to thereby force liquid refrigerant therefrom which supplies the discharge temperature control circuit in all modes of operation.
