1. , for a system for monitoring overheat of compressor, comprising:

  • Compressor, it is connected to vaporizer;

    Suck sensor, it exports and sucks signal, and described suction signal is corresponding to the temperature of refrigeration agent entering described compressor;

    AndControl module, it is connected to the sensor of described vaporizer and described suction sensor, described control module determination evaporator temperature, the temperature sucking the degree of superheat is calculated based on described evaporator temperature and described suction signal, by described suction degree of superheat temperature and the predetermined temperature range with upper limiting temperature and lower limit temperature are compared the superheat state of monitoring described compressor, reduce the speed of described compressor when described suction degree of superheat temperature continues the first predetermined time section between described upper limiting temperature and described lower limit temperature or expansion valve is opened, and described suction degree of superheat temperature be greater than described upper limiting temperature continue the second predetermined time section time stop described compressor, wherein, described second predetermined time section be shorter than described first predetermined time section.
