The invention discloses a vehicle air conditioner self-cleaning method and a related device. The method is applied to the vehicle air conditioning system, the vehicle air conditioning system comprises a controller, a compressor, a heat exchanger and a liquid storage tank, the liquid storage tank is connected with the compressor through a first electromagnetic valve, and the method comprises the steps that the controller receives a self-cleaning instruction; the controller judges the environment temperature according to the self-cleaning instruction; under the condition that the environment temperature exceeds the first preset environment temperature, a first electromagnetic valve is opened, so that the high-pressure side refrigerant is stored in a liquid storage tank; under the condition that the pressure intensity of the low-pressure side refrigerant is lower than a preset pressure intensity threshold value, the first electromagnetic valve is closed; the controller controls the heat exchanger to frost and defrost. According to the invention, frosting can be carried out under the high-temperature working condition, so that self-cleaning of the vehicle air conditioner is realized.

    本申请公开了一种车辆空调自清洁的方法及相关装置。该方法应用于车辆空调系统,车辆空调系统包括控制器、压缩机、换热器以及储液罐,储液罐通过第一电磁阀与压缩机连接,包括:控制器接收自清洁指令;控制器根据自清洁指令判断环境温度;在环境温度超过第一预设环境温度的情况下,打开第一电磁阀使得高压侧冷媒存储至储液罐;在低压侧冷媒的压强低于预设压强阈值的情况下,关闭第一电磁阀;控制器控制换热器结霜以及化霜。通过实施本申请,可以在高温工况下进行结霜从而实现车辆空调的自清洁。
