Abstract

The invention discloses a control method, a control device and a control circuit of an air conditioning system. The air conditioning system comprises a power control module used for controlling output power of an air conditioner, and the power control module comprises a first power module used for controlling output of a first motor of the air conditioning system and a second power module used for controlling output of a second motor of the air conditioning system. The control method comprises the steps of monitoring to learn that one power module in the power control module breaks down, and triggering a power module switching instruction; and controlling the power module which does not break down in the power control module to be switched to the open-loop control mode according to the triggered power module switching instruction, and controlling output of the first motor and the second motor of the air conditioning system. According to the control method, the problem that in the prior art, user experience is affected due to the fact that the integral air conditioner cannot operate after one power module in the air conditioning system breaks down is solved, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method, a control device and a control circuit of an air conditioning system. Background technique [0002] In the prior art, the external unit of the inverter air conditioner includes two types of motors: a fan and a compressor. Generally, the two types of motors are independently controlled by a power module. The power supply of the power module is taken from the rectified bus bar of the AC power supply. When any power module fails, the unit will stop and report a module failure. Before the module returns to normal, the unit will be in an inoperable state. If the module fault is a recoverable fault, the unit can automatically resume normal operation after the cause of the fault disappears. If an unrecoverable fault occurs in the power module, the traditional treatment method is: the unit continues to report a fault and cannot automatically recover to...
