Abstract

The application discloses a restraining method of defrosting noise, a storage medium, a restraining device and an air conditioner. The restraining method comprises the following steps of when the airconditioner enters a defrosting mode, judging whether an auxiliary heating system of the air conditioner is opened or not; if yes, controlling the opening degree of a bypass electronic valve in a coolant loop of the air conditioner and the rotating speed of an indoor fan by a sectional type control strategy in first preset time, so that the opening degree of the bypass electronic valve and the rotating speed of the indoor fan are correlated and increased in a sectional manner; and if no, controlling the opening degree of the bypass electronic valve to be increased gradually to the maximum opening degree, and controlling the rotating speed of the indoor fan to be smaller than or equal to preset rotating speed. Therefore, when the air conditioner enters the defrosting mode, the opening degree of the bypass electronic valve can be increased gradually, air power noise can be effectively reduced, and when the auxiliary heating system is opened, the rotating speed of the indoor fan and the opening degree of the bypass electronic valve are controlled to be correlated, the defrosting noise of the air conditioner can be effectively restrained, and the user experience can be improved,

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...
