The invention is suitable for the technical field of electric vehicle thermal management, and provides an electric vehicle air conditioning system R290 leakage monitoring and alarming system which comprises a shell. An electric compressor, a water-cooled condenser, a liquid storage tank, an electronic expansion valve, a Chiller, a runner plate, an R290 explosion-proof concentration sensor, a controller, a prediction device, a sound alarm, a light alarm, a temperature and pressure sensor and a pipeline channel are arranged in the shell. The prediction device in the system can pre-store and process data detected by the R290 anti-explosion concentration sensor, and can monitor the information that the R290 refrigerant leakage concentration of the air conditioning system is too high, the concentration change rate is too high and the like; and meanwhile, the sound alarm and the light alarm can find the R290 refrigerant leakage problem of the air conditioning system at the first time, so that the safety of a user is guaranteed.

    本发明适用于电动汽车热管理技术领域,提供了一种电动汽车空调系统R290泄漏的监控与报警系统,包括外壳,其特征在于,所述外壳中设置有电动压缩机、水冷冷凝器、储液罐、电子膨胀阀、Chiller、流道板、R290防爆浓度传感器、控制器、预测装置器、声音报警器、灯光报警器、温度压力传感器以及管路通道。该系统中的预测装置器可以对R290防爆浓度传感器检测到的数据进行预储存和处理,能够监控空调系统R290制冷剂泄漏浓度过高以及浓度变化速率过快等信息;同时所述的声音报警器和光照报警器能够第一时间发现空调系统的R290制冷剂泄漏问题,从而保障了用户的安全。
