Fig. 1 shows an updating method for an air conditioning system according to an embodiment, including:

step S101, acquiring a fault type with the fault rate being greater than or equal to a first set value.

And S102, determining parameters to be updated according to the fault type.

And step S103, determining the adjustment quantity of the parameter to be updated according to the fault rate.

In step S101, different faults may occur according to different specific application states of the air conditioning system, for example: the method comprises the steps that the faults of a compressor, the faults of an indoor fan, the faults of an outdoor fan and the like are solved, the parameters of an air conditioner system are adjusted according to different fault types, the same faults of the air conditioner are avoided, and the parameters to be adjusted and the adjustment amount of the related parameters are different according to different fault types. Therefore, in order to improve the accuracy of updating the air conditioning system, in step S102, the parameter to be updated is determined according to the fault type, and in step S103, the adjustment amount of the parameter to be updated is determined according to the fault rate.

Alternatively, the above process is performed by a controller of the air conditioning system or a remote server of the air conditioning system.

And then, the controller of the air conditioning system determines the parameters to be updated according to the fault types and determines the adjustment quantity of the parameters to be updated according to the fault rate. And storing the fault type and the corresponding relation between the fault type and the parameter to be updated in the air conditioning system.
