とする冷凍装置。 The refrigerant discharged from the compressor is circulated through the condenser, the electric motor type expansion valve, and the evaporator in this order to the compressor, and during capacity control operation, a part of the refrigerant gas discharged from the compressor is circulated to the electric motor type expansion valve. In a refrigeration system that leads hot gas to the evaporator via a hot gas bypass circuit having a hot gas control valve, an auxiliary battery is used, and when the current supply from the main power supply stops during capacity control operation, the current from the auxiliary battery is transferred to the electric motor. A refrigeration system comprising a control means for guiding an expansion valve and a hot gas control valve to completely close them.
