The invention provides a refrigerating unit device for a new energy electric refrigerator car with an integrated outdoor unit, and belongs to the technical field of refrigerator car refrigeration, the refrigerating unit device comprises a refrigerating unit and a defrosting unit, and the refrigerating unit comprises an outdoor unit assembly, an indoor unit assembly, a pipe set, a refrigeration and heat preservation compartment and a high-voltage power battery. According to the refrigerating unit of the new energy refrigerator car, the used compressor is the electric compressor, the high-voltage power supply with the same voltage platform as the new energy refrigerator car body is used as a power source of the electric compressor, and the electric compressor is driven to replace a fuel oil belt wheel compressor; and an oil-gas separator, a condenser, a receiver-drier, a thermostatic expansion valve and an evaporator are sequentially arranged on the pipe group between the circulating refrigerant outlet and the circulating refrigerant inlet of the electric compressor. The problem that a power source is generated due to the fact that an existing traditional fuel oil refrigerator car refrigerating unit depends on work of an engine during refrigerating can be solved.
