Abstract (en)
The refrigeration apparatus performs the cooling operation by using a refrigerant circuit in which a refrigerant circulates through a compressor, a condenser, an expansion apparatus, and an evaporator in this order. The refrigeration apparatus includes: a pressure sensor that detects a pressure value of the refrigerant; and a control device that controls a flow of the refrigerant. In a case where the cooling operation is not performed, the control device starts recovery of the refrigerant within the evaporator when the pressure value of the refrigerant detected by the pressure sensor becomes greater than or equal to a first predetermined pressure value. The first predetermined pressure value is set to a value higher than a range of the pressure value detected by the pressure sensor in a case where the cooling operation is performed.
