The invention discloses a pure electric refrigerator car air conditioner composite unit which comprises a compressor, an outside-car condenser, an expansion valve and a warehouse evaporator which are sequentially and circularly connected, and a cab air conditioner unit connected with the expansion valve and the warehouse evaporator in parallel is arranged among the expansion valve, the outside-car condenser and the compressor. And the cab air conditioning unit simultaneously exchanges heat with a power battery of the pure electric refrigerator car and a cab space. According to the technical scheme, the parallel double-circulation refrigerating system is adopted, and the winter heating function of the cab of the pure electric refrigerator car is achieved under the condition that no extra power is consumed. The heating function of the cab air conditioner is achieved through condensation heat release of the cargo hold refrigeration working condition under the winter working condition, and efficient and energy-saving heating is achieved; meanwhile, by means of specific arrangement of refrigerant pipelines, heat preservation of the power battery pack can be achieved so as to prevent electric quantity reduction caused by low temperature of the batteries in winter or provide cooling for the power battery pack in summer.

    本发明公开了一种纯电动冷藏车空调复合机组,包括依次循环连接的压缩机、车外冷凝器、膨胀阀、货仓蒸发器,所述膨胀阀、车外冷凝器与所述压缩机之间设置有与所述膨胀阀货仓蒸发器并联的驾驶室空调单元,驾驶室空调单元同时与纯电动冷藏车的动力电池、驾驶室空间进行热交换。本技术方案采用并联双循环制冷系统,在不额外耗电的情况下,实现对纯电动冷藏车驾驶室的冬季供暖功能。本发明冬季工况下用货舱冷藏工况的冷凝放热,来实现驾驶室空调的制热功能,实现了高效、节能地制热;同时,通过对制冷剂管路的特定排布,还可以实现对动力电池组的保温以防止冬季电池因低温导致的电量下降,或在夏季对动力电池组提供冷却。
