The invention discloses a vehicle-mounted air conditioner standby refrigerating system which comprises a compressor, a condenser, an evaporator, a controller, a first pressure sensor located on the air conditioner pipeline in the outlet direction of the condenser, and a second pressure sensor located on the air conditioner pipeline in the inlet direction of the compressor. A reversing valve is arranged on the air conditioner pipeline between the compressor and the condenser, a guide valve is arranged on the air conditioner pipeline between the compressor and the second pressure sensor, the reversing valve and the guide valve are connected with a standby device through another branch pipeline, and the reversing valve can be connected between the condenser and an upper port of the compressor or an upper port of the standby device. The guide valve can establish connection between the evaporator and the lower port of the compressor or the standby device; after an air conditioner compressor is damaged in summer, flowing of refrigerants in an air conditioner pipeline and operation of an air conditioner system can still be maintained within the set time, the refrigerating capacity of an air conditioner is kept, and an automobile can be conveniently driven to be maintained nearby.
本发明公开了一种车载空调备用制冷系统,包括由空调管路相互连通的压缩机、冷凝器、蒸发器、控制器及位于冷凝器出口方向空调管路上的压力传感器一、位于压缩机入口方向空调管路上的压力传感器二,压缩机与冷凝器之间的空调管路上设有换向阀,压缩机与压力传感器二之间的空调管路上设有导向阀,换向阀与导向阀分别通过另一支管路与备用器连接,换向阀能够在冷凝器与压缩机或备用器的上端口之间建立连接,导向阀能够在蒸发器与压缩机或备用器的下端口之间建立连接;在夏季空调压缩机损坏后,仍然能够在设定时间内、维持空调管路内制冷剂的流动及空调系统的运转,保持空调的制冷能力,以便汽车行驶至就近维修。
