A refrigerant circuit (21) is configured, which includes an electric compressor (22), a condenser (23), an expansion mechanism (24), an evaporator (25), a hot gas introduction path (123) connecting the electric compressor (22) and the evaporator (25) together, and a switching valve (143) for controlling a flow of refrigerant in the hot gas introduction path (123). In addition, a fan (26) is provided. In a defrosting cycle for introducing refrigerant into the evaporator (25) through the hot gas introduction path (123) to defrost the evaporator (25), if the pressure of the condenser (23) is equal to or lower than a predetermined threshold, the fan (26) forms an air flow from a radiator (45) to the condenser (23).
