VIN:WBAFB31090LP03340 故障现象:车主反映车辆运行后,将仪表板空调控制面板的温度设置至最低,出风口依然感觉凉度明显不足。故障诊断:在空调管路上连接空调压力表,启动运转发动机,将自动空调的温度设置在18℃,观察压力表变化状况。低压管路的压力降至225k Pa,高压管路的压力升至 1200kPa,说明压缩机吸合工作。用手触摸空调低压管路的温度,感觉温热,而冷凝器与蒸发器之间的高压管路的温
VIN: WBAFB31090LP03340 Symptom: Vehicle owners reflect the operation of the vehicle, the dashboard air conditioner control panel temperature is set to a minimum, the outlet still felt significantly less than the degree of cooling. Troubleshooting: Air conditioning pipe connected to the air conditioning pressure gauge, start running the engine, the automatic air conditioning temperature is set at 18 ℃, observe the pressure gauge changes. The pressure in the low-pressure line drops to 225k Pa, and the pressure in the high-pressure line rises to 1200kPa, indicating that the compressor is engaged. Touch the temperature of the air conditioning low-pressure pipe by hand, feel warm, and the temperature of the high-pressure pipe between the condenser and the evaporator
