A multi-compartment transport refrigeration system includes a compressor (20) having suction port, discharge port and intermediate inlet port; a heat rejecting heat exchanger (116); an economizer heat exchanger (148) having a first refrigerant flow path and a second refrigerant flow path therethrough; a first evaporator expansion device (140); a first evaporator (40)having an inlet coupled to the first evaporator expansion device and an outlet coupled to a compressor inlet path, the first evaporator for cooling a first compartment of a container; a second evaporator expansion (150); a second evaporator (50) having an inlet coupled to the second evaporator expansion device, the second evaporator for cooling a second compartment of the container; an economizer expansion device (77) coupled to the first refrigerant flow path, the economizer expansion device directing refrigerant from the first refrigerant flow path to the second refrigerant flow path, the second refrigerant flow path coupled to the intermediate inlet port. |
