传统的汽车空调系统均采用定排量式空调压缩机,它根据蒸发器出风口温度来控制空调压缩机电磁离合器的接合与分离,从而达到控制制冷效果的目的。这种控制方式除了车内温度波动大,系统能耗增加等缺点外,最大的一个缺点是压缩机间歇性地离合会对发动机的正常工作有干扰,这在 The traditional car air-conditioning systems are used fixed-displacement air-conditioning compressor, which according to the evaporator outlet temperature control air conditioner compressor electromagnetic clutch engagement and separation, so as to achieve the purpose of controlling the cooling effect. This control method in addition to the vehicle temperature fluctuations, the system increased energy consumption and other shortcomings, the biggest drawback is that the compressor intermittently clutch will interfere with the normal work of the engine, which is
