Beschreibung
Zusammenfassung:	A compartmentalized transport refrigeration system which holds selected set point temperatures in at least first and second served spaces via heating and cooling cycles. The system includes a refrigerant circuit having high and low pressure sides, including a compressor, a condenser, a receiver, at least first and second evaporator sections respectively associated with the first and second served spaces, an accumulator, and a mode selector valve having heating and cooling positions. Control provides a heat signal when the need for a heating cycle in one of the served spaces is detected. The receiver is connected to the low pressure side of the refrigerant circuit for a predetermined period of time in response to the heat signal. At the end of the period of time the mode selector valve is operated from the cooling position to the heating position, and the connection between the receiver and low pressure side is terminated.
