1. it is a kind of detection air conditioning system coolant method, it is characterised in that comprise the following steps:

  • Start compressor operating, whether the first kind parameter for detecting air conditioning system meets first pre-conditioned, wherein, described firstClass parameter at least includes:

    The line temperature of the vaporizer of the air conditioning system;

    If the first kind parameter of the air conditioning system meets described first pre-conditioned, the electronics for adjusting the air conditioning system is swollenSwollen valve, and continuing to monitor the line temperature of the vaporizer, whether to meet second pre-conditioned;

    If the line temperature for monitoring the vaporizer meets the described second pre-conditioned, holding electric expansion valve adjustmentAperture afterwards, and adjust the air conditioning system compressor frequency to preset frequency;

    AndDuring the compressor is according to preset frequency work, whether the first kind parameter of the detection air conditioning systemMeet the 3rd pre-conditioned, if the first kind parameter for detecting the air conditioning system meets the described 3rd pre-conditioned, reallyThere is the failure for lacking coolant in the fixed air conditioning system.
