The invention provides a refrigeration air-conditioning system of an electric refrigerator car, which comprises a refrigerating compartment refrigerant circulating system, a driving room refrigerant circulating system and an anti-freezing solution circulating system, and the three circulating systems can change connection schemes according to different use scenes of the refrigerator car to cooperatively realize multiple working modes. The cold storage system has the beneficial effects that when the refrigerator car is parked, electricity is directly taken from the charging pile for cold storage (battery electric energy does not need to be consumed), when the refrigerator car is used, only a small amount of electricity is needed to drive the circulating pump, the heat exchanger fan and other equipment to release the stored cold energy, and cold supply of the refrigerating compartment and the driving and riding room can be achieved; the refrigeration air-conditioning system is prevented from greatly consuming electric energy of a vehicle-mounted battery In addition, cold energy stored by the phase change energy storage device is utilized in a gradient mode, waste heat generated by a refrigeration system of the refrigeration compartment is effectively utilized, cooling and heating are provided for the driving and riding room, efficient refrigeration and heating are guaranteed, and meanwhile the problem that the endurance of the whole electric refrigerator car is affected due to high power consumption of a refrigeration air conditioning system is solved.

    本发明提供一种电动冷藏车制冷空调系统,包括冷藏厢制冷剂循环系统、驾乘室制冷剂循环系统和防冻液循环系统,且这三种循环系统可按冷藏车使用场景的不同改变连接方案,协同实现多种工作模式。本发明的有益效果:在冷藏车驻车时,本发明直接从充电桩取电进行储冷(无需消耗电池电能),在冷藏车使用时,本发明仅需少量电力驱动循环泵和换热器风机等设备将储存的冷能释放,即可实现冷藏厢和驾乘室供冷,避免制冷空调系统大量消耗车载电池电能;此外,本发明还通过梯级利用相变储能装置储存的冷能、有效利用冷藏厢制冷系统产生的废热,为驾乘室供冷暖,在保证高效制冷、供暖的同时,解决了电动冷藏车因制冷空调系统电耗高而影响整车续航的问题。
