Air conditioner fault auxiliary rapid diagnosis control method

The invention discloses an air conditioner fault auxiliary rapid diagnosis control method. The air conditioner fault auxiliary rapid diagnosis control method comprises the following steps that air conditioner constraint coding is conducted, wherein various constraints during running of an air conditioner are coded; constraint type displaying is conducted, wherein during running of the air conditioner, when the running frequency of a compressor of the air conditioner becomes abnormal due to the constraints, the constraint causing the abnormal change of the frequency is found, and a corresponding displaying device is controlled to conduct displaying according to coding of the constraint. According to the air conditioner fault auxiliary rapid diagnosis control method, current common constraint control conditions of the air conditioner are utilized fully, due to the fact that necessary relation exists between constraint producing and faults in some links of the air conditioner, before the air conditioner breaks down, in other words, the frequency of the compressor changes due to the constraint condition, the type of the constraint can be displayed in a coding mode, and technicians can check the type of the constraint conveniently and can quickly position the fault.
