The invention is suitable for the technical field of electric vehicle thermal management, and provides a refrigerant leakage detection and elimination system for a totally-closed air conditioning system of an electric vehicle. Comprising an electric compressor, a first plate heat exchanger, an electronic expansion valve, a second plate heat exchanger, a gas-liquid separator, a temperature pressure sensor, an R290 anti-explosion concentration sensor, a processor, a controller, a first gas inlet pipe, a first valve, a second gas inlet pipe, a fan induced draft fan, a first exhaust pipe, a second valve, a combustor, a combustion reaction area and an ignition device. When the system is used, R290 ultra-low concentration acquisition-processing-control technology collaboration can be achieved, when the R290 leakage concentration or the R290 leakage instantaneous concentration gradient exceeds an early warning set value, a controller can control a valve, a fan induced draft fan and a high-voltage electric spark device to be started, and the R290 leakage concentration or the R290 leakage instantaneous concentration gradient exceeds the early warning set value. The R290 gas leaked from the closed system of the air conditioner and the air are combusted in the combustion reaction area, the active elimination technology is achieved, and therefore the safety of a user is effectively 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全封闭空调系统制冷剂泄漏检测与消除系统,包括:电动压缩机、第一板式换热器、电子膨胀阀、第二板式换热器、气液分离器、温度压力传感器、R290防爆浓度传感器、处理器、控制器、第一进气管、第一阀门、第二进气管、风扇引风机、第一排气管、第二阀门、燃烧器、燃烧反应区和点火装置。该系统在使用时能够实现R290的超低浓度采集‑处理‑控制的技术协同,当R290泄漏浓度或R290泄漏瞬时浓度梯度超过预警设定值时,控制器会控制阀门、风扇引风机以及高压电火花装置的开启,使空调封闭系统内泄漏的R290气体与空气在燃烧反应区内燃烧,实现主动消除技术,从而有效保障了用户的安全。
