Abstract
A refrigerant circuit is configured, which includes an electric compressor, a condenser, an expansion mechanism, an evaporator, a hot gas introduction path connecting the electric compressor and the evaporator together, and a switching valve for controlling a flow of refrigerant in the hot gas introduction path. In addition, a fan is provided. In a defrosting cycle for introducing refrigerant into the evaporator through the hot gas introduction path to defrost the evaporator, if the pressure of the condenser is equal to or lower than a predetermined threshold, the fan forms an air flow from a radiator to the condenser.
