Abstract
A refrigeration device includes a control unit, and a refrigerant circuit in which a compression mechanism, a radiator, a refrigerant cooling unit, a first expansion mechanism, a liquid receiver, a second expansion mechanism, and an evaporator are connected in sequence. The control unit performs refrigerant cooling control whereby the refrigerant is cooled by the refrigerant cooling unit so that the state of the refrigerant that has flowed out from the first expansion mechanism is near the saturation line and not near the critical point.
