Sub-engine type refrigeration system for transportation 1 that drives all or part of a chiller's electric load 7 by power generated by an AC generator 3, including a secondary battery 8 which is capable of storing power generated by the AC generator 3, and a control unit 12 which controls so that, when a state of charge of the secondary battery 8 is at or above a control lower limit value, an engine 2 is stopped and a chiller's electric load 7 is driven by power of the secondary battery 8, and when the state of charge of the secondary battery 8 is below the control lower limit value while the chiller's electric load 7 is driven by the power of the secondary battery 8, the engine 2 is operated and the AC generator 3 starts power generation. |
