Abstract (en)
[origin: EP2068093A1] An object of this invention is to enable the refrigerant level in a liquid receiver to be stably controlled even when the high-pressure-side refrigerant is in a subcritical state in a refrigeration device that comprises a refrigerant circuit in which a compressor, a radiator, a first expansion valve, a liquid receiver, a second expansion valve, and an evaporator are connected in sequence. The refrigeration device (1, 101) of this invention is provided with a compression mechanism (11), a radiator (13), a first expansion mechanism (15), a liquid receiver (16), a second expansion mechanism (17, 33a, 33b), an evaporator (31, 31a, 31b) and a control unit (23). The control unit minimizes the degree of pressure reduction by the first expansion mechanism when the refrigerant that flows from the refrigerant discharge side of the compression mechanism to the refrigerant inflow side of the first expansion mechanism has reached a subcritical state.
