PROBLEM TO BE SOLVED: To provide a refrigerator-freezer unit including a ventilator function to circulate the air stagnating on the upper surface of a prefabricated refrigerator-freezer and ensuring an effective ventilation function even if a compressor stops, without the need to newly install a ventilator.SOLUTION: A refrigerator-freezer unit comprises a refrigerant circuit in which a compressor compressing refrigerant, a condenser condensing high-pressure refrigerant gas from the compressor, a condenser blower blowing air to the condenser, an expansion valve expanding high-temperature, high-pressure liquid refrigerant from the condenser, and an evaporator evaporating low-temperature, low-pressure refrigerant from the expansion valve are sequentially connected by a refrigerant tube, and causes a refrigerator-freezer to perform cold storage or refrigeration. In a state in which the compressor and the condenser blower stop operating, the condenser blower that stops operating is driven if an outside temperature of the refrigerator-freezer is equal to or higher than an outside set temperature. |
