An automobile body air conditioner evaporator protection system comprises a control unit, a standard voltage input unit, an acquisition unit, an execution unit and a power supply unit. The acquisition unit is arranged in an evaporator of the vehicle body air-conditioning system, the output end of the acquisition unit and the output end of the standard voltage input unit are respectively connected with two input ends of the control unit, the output end of the control unit is connected with the control end of the execution unit, and the output of the execution unit controls a working power supply of a compressor of the vehicle body air-conditioning system. When the acquired voltage is smaller than the critical standard voltage, the execution unit switches on a compressor working power supply, and the compressor runs; when the collected voltage is larger than the critical standard voltage, the execution unit cuts off the working power supply of the compressor, and the compressor stops working. The protection system is high in temperature protection precision, good in response sensitivity, capable of effectively prolonging the service life of the compressor, convenient to install, easy and efficient to maintain, low in implementation cost, capable of saving energy, environmentally friendly, capable of reducing consumption, easy to popularize and good in market prospect.

    一种汽车车身空调蒸发器保护系统,包括控制单元、标准电压输入单元、采集单元、执行单元和电源单元;所述采集单元置于车身空调系统的蒸发器内,其输出端以及标准电压输入单元的输出端分别接控制单元的两输入端,控制单元的输出端接执行单元的控制端,执行单元的输出控制车身空调系统之压缩机的工作电源。当采集电压小于临界标准电压时,执行单元接通压缩机工作电源,压缩机运行;当采集电压大于临界标准电压时,执行单元切断压缩机工作电源,压缩机停止工作。该保护系统温度保护精度高、响应灵敏度好,不仅能有效延长压缩机使用寿命,而且安装方便、维护简单高效,实施成本低,节能环保、降耗,易于推广、市场前景好。
