A bottle cooler system (20, 70, 100) includes a compressor (22), a first heat exchanger (24) and a second heat exchanger (28). In a cooling mode of operation, the second heat exchanger is downstream of the first heat exchanger and upstream of the compressor to cool contents of an interior volume. In a defrost mode of operation, refrigerant in the second heat exchanger is used to defrost an ice build-up on the second heat exchanger.

摘要:
A system has a compressor. A heat rejection heat exchanger is coupled to the compressor to receive refrigerant compressed by the compressor. An ejector has a primary inlet coupled with heat rejection heat exchanger to receive refrigerant, a secondary inlet, and an outlet. The system has a heat absorption heat exchanger. The system includes means for providing at least of a 1-10% quality refrigerant to the heat absorption heat exchanger and an 85-99% quality refrigerant to at least one of the compressor and, if present, a suction line heat exchanger.

A transport refrigerant vapor compression system includes a controller for controlling operation of the transport refrigerant vapor compression system. The controller is configured to modulate a discharge pressure of the refrigerant compression device to control a cooling capacity of the transport refrigerant vapor compression system. The controller is configured to modulate the discharge pressure of a refrigerant compression device to control the cooling capacity of the transport refrigerant vapor compression system using both a refrigerant reservoir and an auxiliary expansion device without affecting superheat of the transport refrigerant vapor compression system.
