The invention discloses a monitoring system suitable for track air conditioner refrigerant leakage, which comprises a refrigerant circulating system consisting of a compressor, a condenser and an evaporator, and further comprises a high-pressure pressure sensor, a low-pressure pressure sensor and a refrigerant temperature sensor, the high-pressure pressure sensor is arranged at an exhaust pipe of the compressor, the low-pressure pressure sensor is arranged at an air return pipe of the compressor, and refrigerant temperature sensors are arranged at an outlet pipeline of the condenser and an outlet pipeline of the evaporator; the high-pressure pressure sensor, the low-pressure pressure sensor and the refrigerant temperature sensor upload refrigerant temperature and operation pressure data to a controller of a train air conditioner in real time for calculation and analysis, an analysis result is judged by the controller, and when the monitored refrigerant state operation is abnormal, an alarm signal is reported to a vehicle control system, so that the train air conditioner operates normally. And early warning and maintenance are carried out in advance. According to the invention, the state of the refrigerant in the pipeline is monitored in real time for early warning, and maintenance personnel can carry out maintenance in advance.

    本发明公开了一种适用于轨道空调制冷剂泄漏的监测系统,包括由压缩机、冷凝器和蒸发器组成的制冷剂循环系统,还包括高压压力传感器、低压压力传感器和制冷剂温度传感器;高压压力传感器布置在压缩机排气管处,低压压力传感器布置在压缩机回气管处,冷凝器出口管路处及蒸发器出口管路处设有制冷剂温度传感器;高压压力传感器、低压压力传感器和制冷剂温度传感器将制冷剂温度、运行压力数据实时上传到列车空调的控制器进行计算和分析,分析结果由控制器进行判断,当监测的制冷剂状态运行异常后,将上报警报信号到车辆控制系统,提前进行预警和维护。本发明对制冷剂在管路中的状态进行实时监测进行预警,维护人员可以提前进行检修。
