Abstract

The invention relates to the technical field of household appliances, and particularly provides an air conditioner and a control method and device thereof. The air conditioner control method comprises the steps that during the heating operation period of an air conditioner, a first difference value between the current indoor temperature and the temperature set by a user is obtained; in response to the situation that the first difference value is not smaller than a preset threshold value and the air outlet direction of an indoor unit of the air conditioner in the vertical direction is lower than a preset angle, the air outlet direction is adjusted to be larger than the preset angle; and in response to the situation that the air conditioner meets the defrosting starting condition, the air conditioner is controlled to be switched from heating operation to defrosting operation. In the embodiment of the invention, heat is stored for the indoor upper-layer air during the heating operation of the air conditioner, so that sudden drop of the indoor temperature is avoided during the defrosting operation, and the heating experience is improved. In addition, due to the fact that the upper-layer air has more heat, the indoor unit heat exchanger can absorb more heat in the defrosting operation process, defrosting of the outdoor unit heat exchanger is accelerated, and the defrosting effect is improved.

Description

technical field [0001] The present disclosure relates to the technical field of household appliances, in particular to an air conditioner and a control method and device thereof. Background technique [0002] When the air conditioner is in heating operation, the outdoor unit heat exchanger needs to absorb heat from the outside, and the temperature of the heat exchanger itself will drop below zero, causing moisture to condense into frost on the outdoor unit heat exchanger. This phenomenon is called air conditioner. frost. [0003] At present, the defrosting (also called defrosting) method of air conditioners generally adopts reverse cycle defrosting, that is, the defrosting device system is switched from the heating mode to the cooling mode, and the heat of the compressor and refrigerant is used to complete the outdoor heat exchanger. Defrost. However, in the related art, when the air conditioner defrosts, the indoor temperature drops a lot, and the user experience is poor....
