Abstract

The invention discloses a defrosting control method, a device and an air conditioner. Wherein, the method includes: acquiring outdoor environment data when the air conditioner is operating in a heating mode; determining a corresponding target value of the air conditioner operating capacity attenuation according to the outdoor environment data; when the actual value of the air conditioner operating capacity attenuation reaches the When the target value is reached, the air conditioner is controlled to switch to the defrosting mode. Through the present invention, considering the influence of environmental factors on the defrosting execution effect, combined with the use environment of the air conditioner, the optimal timing for defrosting execution adapted to the outdoor environment is determined, the optimal control of defrosting is realized, and ineffective defrosting is avoided. It can realize frost-free operation of the air conditioner, and solve the problem of poor defrosting effect in the prior art when the air conditioner is in a bad use environment.

Description

technical field [0001] The present invention relates to the technical field of defrosting, and in particular, to a defrosting control method, a device and an air conditioner. Background technique [0002] When the air conditioner is in heating operation, due to the low outdoor ambient temperature, the surface of the outdoor heat exchanger is prone to frost, and the frost layer will affect the heat exchange efficiency of the outdoor heat exchanger, thereby affecting the heating or cooling capacity of the air conditioner. Defrost. Defrost corresponds to the cooling mode, which will reduce the indoor temperature and affect user comfort. [0003] The defrosting process is a process of energy attenuation (that is, the heating capacity is reduced), because the reverse cycle defrosting corresponds to the cooling mode, and the reduction of the heat exchange temperature difference on the indoor side reduces the heat exchange capacity, thereby reducing the heating capacity. If the o...
