The invention discloses a vehicle-mounted freezing and refrigerating air conditioning system. Comprising a compressor 1, a condenser 2, a refrigerating chamber evaporator 3a, a freezing chamber evaporator 3b, a cab air heat exchanger 3c, a first gas-liquid separator 4a, a second gas-liquid separator 4b, a first throttling component 5a, a second throttling component 5b, a third throttling component 5c, a flash evaporation steam separator 6, a first electric control valve 7a, a second electric control valve 7b, a third electric control valve 7c, a first one-way valve 8a and a second one-way valve 8b. And a first regulating valve 9a and a second regulating valve 9b. According to the system, two-stage compression is achieved through one compressor, the functions of refrigeration, freezing and cab air conditioning are achieved, throttling losses are reduced, power consumption of the compressor is reduced, the energy efficiency of the system is improved, and therefore energy consumption and transportation cost in cold-chain logistics are reduced.

    本发明公开了一种车载冷冻冷藏空调系统,包括压缩机1、冷凝器2、冷藏室蒸发器3a、冷冻室蒸发器3b、驾驶室空气换热器3c、第一气液分离器4a、第二气液分离器4b、第一节流部件5a、第二节流部件5b、第三节流部件5c、闪发蒸气分离器6、第一电动控制阀7a、第二电动控制阀7b、第三电动控制阀7c、第一单向阀8a、第二单向阀8b、第一调节阀9a、第二调节阀9b。该系统采用一台压缩机实现双级压缩,实现冷藏、冷冻、驾驶室空调功能的同时,减小了节流损失,降低了压缩机的功耗,提高了系统能效,从而降低了冷链物流中的能耗及运输成本。
