Embodiment Construction

[0046] When the air conditioner is running in heating mode, the heat exchanger on the outside of the air conditioner will gradually frost. The frost layer will prevent heat transfer. As the air conditioner continues to operate, the frost layer will continue to thicken. The heating performance of the air conditioner is affected by the frost layer and decreases. If no defrosting is performed at this time, the frost layer will become thicker and thicker, which will affect the heating effect of the air conditioner. Aiming at the existing defrosting method, the present invention A new defrosting control method for air conditioners is provided. By turning on the electric auxiliary heating, reversing the internal motor and adjusting the speed of the internal motor, the defrosting time is shortened and the indoor temperature is kept stable, which improves the user experience.

Abstract

The invention provides an air-conditioner defrosting control method and device, an air conditioner and a computer-readable storage medium. The defrosting control method comprises the following steps that when the air conditioner receives a defrosting signal, a four-way valve is controlled to reverse; an electrical auxiliary heating device is started, and a current set temperature Ts and a currentinner ring temperature Tin of the air conditioner are detected continuously; an inner motor is rotated reversely and operates at an initial speed N; and the speed of the inner motor is adjusted according to the detected set temperature and the detected inner ring temperature. According to the air-conditioner defrosting control method and device, the air conditioner and the computer-readable storage medium, defrosting can be accelerated, the indoor temperature is kept stable, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and device, an air conditioner and a computer-readable storage medium. Background technique [0002] With the improvement of people's living standards, air conditioners have become an indispensable household appliance for every family. After the air conditioner continues to heat and run for a period of time, frost will appear on the outdoor heat exchanger. The frost layer will prevent heat transfer, and the heating performance of the air conditioner will decrease, affecting the use effect. After the frost layer reaches a certain thickness, it needs to be defrosted. [0003] The existing defrosting method is mainly to change the direction of the four-way valve, switch the heating mode to the cooling mode, and absorb the heat in the room and the heat retained in the compressor during the flow of the refrigerant, and the...
