摘要： A reversible HVAC heating/cooling refrigerant system includes a novel valve system that allows an outdoor heat exchanger to function as a subcooler during a cooling or defrost mode and function as a receiver tank for storing excess liquid refrigerant during a heating mode. In the heating mode, a cooling expansion valve is kept slightly open to flood the subcooler with liquid refrigerant while a heating expansion valve is regulated to maintain a desired level of superheat at the suction side of the refrigerant system's compressor. The novel valve system also serves as a pressure relief valve to protect the subcooler from excess pressure caused by thermal expansion of liquid refrigerant trapped within the subcooler.

摘要： A refrigeration device (1) includes a switching valve control section (58) for outputting a switching signal for controlling a four-way switching valve (20) to a predetermined switching state when starting a compression mechanism (40); and a switching determination section (59) which, when starting only a first compressor (14a) as a start-up of the compression mechanism (40), outputs a low differential pressure signal if a differential pressure between a high-pressure port (P1) and a low-pressure port (P3) in the four-way switching valve (20) falls below a determination value in a determination operation after the switching signal being outputted by the switching valve control section (58). After the switching determination section (59) outputs the low differential pressure signal, a capacity control section (51) starts a second compressor (14b).
