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.
