PROBLEM TO BE SOLVED: To provide a refrigerator for transportation capable of not only resolving a problem of a lack of heating capacity due to a gas-low status in a system but also properly and efficiently warming up each chamber regardless of the setting temperature when multiple chambers are simultaneously warmed up.SOLUTION: A refrigerator-outside unit 3 provided with a compressor 4, a refrigerator-outside heat exchanger 8, a heating-up expansion valve 14, a refrigerator-outside fan 20, and the like is connected in series with multiple refrigerator-inside units 2A and 2B comprising refrigerator-inside heat exchangers 9A and 9B, cooling expansion valves 15A and 15B, refrigerator-inside fans 21A and 21B, and the like. In a refrigerator 1 for transportation capable of cooling or heating up multiple chambers A and B individually provided with the refrigerator-inside units 2A and 2B, the method for heating the multiple chambers A and B is a heat pump heating method which absorbs the heat by the refrigerator-outside heat exchanger 8 to heat up the heat by releasing the heat by the refrigerator-inside heat exchangers 9A and 9B. When each of the chambers A and B is heated up, the respective chambers A and B are individually and alternately switched to heat up the heat. |
