1. a kind of Defrost method of air-conditioning, which is characterized in that comprise the following steps:

  • Step 1, environment temperature, ambient humidity and fin temperature are gathered;

    Step 2, the environment temperature and the dew-point temperature corresponding to ambient humidity are calculated, according to the fin temperature and the dewRelation between point temperature, judges whether fin meets the condition of frosting;

    If met, 3 are entered step, otherwise, returns to stepRapid 1;

    Step 3, pressure of inspiration(Pi) is gathered, and calculates evaporating temperature and its change rate corresponding to the pressure of inspiration(Pi), if describedChange rate is greater than or equal to predetermined variation rate, then starts to defrost;

    Otherwise, step 3 is continued.
