摘要: A sub-engine (30), a compressor (40) driven by the sub-engine (30), and a refrigeration circuit (70) connected to the compressor (40) and operable in a vapor compression refrigeration cycle are provided, and the interior of a refrigerator (13) of a refrigerated vehicle (10) is cooled. A rotational speed control unit (91) for linearly controlling fluctuations in the rotational speed of the sub-engine (30) such that the refrigeration capacity grows or declines in response to a refrigeration load is provided. A battery (51) for storing electric power and an electric generator (50) for generating electric power by the rotational drive of the refrigerating engine (30) to store the generated electric power in the battery (51) are provided. A fan motor (7a) for the refrigeration circuit (70) is selectively connectable to the electric generator (50) and the battery (51) such that power is fed from one of the electric generator (50) and the battery (51) to the fan motor (7a).
