Abstract

The present application discloses a method for suppressing defrosting sound, a storage medium, a suppressing device, and an air conditioner. The suppressing method includes the following steps: when the air conditioner enters the defrosting mode, it is judged whether the auxiliary heating system of the air conditioner is turned on; if If yes, use a segmented control strategy to control the opening of the bypass electronic valve and the speed of the indoor fan in the refrigerant circuit of the air conditioner within the first preset time, so that the opening of the bypass electronic valve and the speed of the indoor fan If not, control the opening of the bypass electronic valve to gradually increase to the maximum opening, and control the speed of the indoor fan to be less than or equal to the preset speed. Therefore, when the air conditioner enters the defrosting mode, the opening degree of the bypass electronic valve is gradually increased, which can effectively reduce the aerodynamic noise, and when the auxiliary heating system is turned on, the rotation speed of the indoor fan and the bypass electronic valve are controlled. The valve opening is correlated, which effectively suppresses the defrosting sound of the air conditioner and improves the user experience.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for suppressing defrosting noise, a storage medium, a suppressing device and an air conditioner. Background technique [0002] In the defrosting mode, air conditioners in the related art generally adopt the following two methods for defrosting: one is reversing defrosting, that is, when the defrosting condition is reached, the whole machine stops the heating state and switches to the cooling state, so that the heat Reversely reaches the outdoor evaporator to achieve the purpose of defrosting. The other is heat storage (electric heating) defrosting. When the defrosting condition is reached, the whole machine does not stop the heating state, and uses the heat of the heat storage device to exchange heat with the outside. device to defrost. [0003] However, whether it is thermal storage (electric heating) defrosting or reverse heating defrosting, when the air cond...
