[0042] This embodiment provides a defrosting control method for an air conditioner. The method is applied to the air conditioner 100. When the air conditioner 100 works at a low temperature, the surface temperature of the evaporator will reach below zero, and the surface of the evaporator may freeze. Frost, when frost forms, the air conditioner 100 needs to be defrosted to prevent frost from affecting the heating performance of the air conditioner 100 . see figure 2 , The air conditioner defrosting control method provided in this embodiment includes S1-S6.

[0043] S1: Control the air conditioner 100 to perform the first defrosting when the air conditioner 100 triggers any first defrosting condition.

[0044] Under the low temperature condition, after the air conditioner 100 starts the heating operation from the shutdown state, if the first defrosting condition is triggered, the first defrosting will be performed. The low temperature condition refers to the temperature rang...

Abstract

The invention provides an air conditioner defrosting control method and device, and an air conditioner. The air conditioner defrosting control method includes the steps that the outer pipe temperatureof the air conditioner is continuously acquired at a preset time interval; an acquired outer pipe temperature data set is compared with a preset temperature, when the acquired plurality of outer pipetemperature data meet the preset condition, the air conditioner is controlled to perform defrosting, and it is avoided that the phenomenon of frequent defrosting or defrosting without frost occurs, and heating comfort of the air conditioner is affected. By acquiring the outer pipe temperature data set, meanwhile the observation period on the air conditioner is prolonged, when the acquired plurality of outer pipe temperature data meet the preset condition, the air conditioner is controlled to perform defrosting, it is avoided that the phenomenon of frequent defrosting or defrosting without frost occurs, and heating comfort of the air conditioner is affected, and the precision of defrosting of the air conditioner without an outdoor environment temperature sensing device is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and device and an air conditioner. Background technique [0002] When the air conditioner is heating in winter, the surface temperature of the evaporator will reach below zero, and frost may form on the surface of the evaporator. The thick frost layer will block the air flow and affect the heating capacity of the air conditioner, so the air conditioner needs to be regularly run defrost. [0003] Existing air conditioners judge whether to defrost by the outdoor ambient temperature and the temperature of the outer tube of the air conditioner. For some air conditioners that are not equipped with an outdoor environment temperature sensing device, they can only use timed defrosting or fixed value of the outer tube temperature. The defrosting method is used to defrost, which is prone to frequent defrosting, or even no frost defrost...
