Problems solved by technology

[0002] In the prior art, when the air conditioner operates in heating mode in winter, the indoor unit acts as a condenser, and the outdoor unit acts as an evaporator, absorbing heat from the outdoors and transferring it to the indoors, so the outdoor unit is prone to frost due to overcooling
The currently used defrosting methods include hot gas defrosting and reversing defrosting. However, in the prior art, the defrosting method is mainly determined according to the parameters such as the thickness of the frost layer and the defrosting time, and does not take into account the environmental parameters and the air conditioner. operating parameters, resulting in poor defrosting effect or poor user experience

Abstract

The invention provides an air conditioner defrosting method and device and an air conditioner. The air conditioner defrosting method comprises the following steps that reference data are obtained, andthe reference data comprise environmental parameters and air conditioner running parameters; when the reference data meet the preset defrosting judgment conditions and the hot air defrosting conditions, the air conditioner is controlled to carry out hot air defrosting; and / or, when the reference data meet the preset defrosting judgment condition but do not meet the hot air defrosting condition, the air conditioner is controlled to carry out reversing and defrosting, the optimal defrosting mode can be selected in a self-adaptation mode, and the advantages of hot air defrosting and reversing defrosting are fully utilized, so that the heating operation efficiency of the air conditioner is improved, and the low-temperature heating comfort is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner defrosting method, device and air conditioner. Background technique [0002] In the prior art, when the air conditioner operates in heating mode in winter, the indoor unit acts as a condenser and the outdoor unit acts as an evaporator, absorbing heat from the outdoors and transferring it to the indoors, so the outdoor unit is prone to frost formation due to overcooling. The currently used defrosting methods include hot gas defrosting and reversing defrosting. However, in the prior art, the defrosting method is mainly determined according to the parameters such as the thickness of the frost layer and the defrosting time, and does not take into account the environmental parameters and the air conditioner. operating parameters, resulting in poor defrosting effect or poor user experience. [0003] Therefore, accurately selecting a suitable defrosting method to impr...
