一辆三菱太空车,因在行驶过程中突然出现空调不制冷,但鼓风机能正常工作的现象,而到我厂维修。检查中发现空调系统压力正常,而空调压缩机电磁离合器不吸合。首先检查电磁离合器,电阻为3Ω,正常,直接向其提供12 V电源,电磁离合器能正常吸合。空调压缩机离合器的吸合受控于压力开关、蒸发器温度传感器、空调 A Mitsubishi space car, because in the course of the sudden air conditioning is not cooling, but the blower can work properly phenomenon, and to my factory maintenance. Check the air-conditioning system found normal pressure, and air-conditioning compressor electromagnetic clutch does not pull. First check the electromagnetic clutch, the resistance of 3Ω, normal, to provide 12 V power directly to the electromagnetic clutch can pull properly. A / C compressor clutches controlled by pressure switch, evaporator temperature sensor, air conditioner
