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

[0043] S1: When the air conditioner 100 triggers any first defrost condition, the air conditioner 100 is controlled to perform the first defrost.

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

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 present invention relates to the technical field of air conditioners, in particular to a defrosting control method and device for an air conditioner, 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, the surface of the evaporator may be frosted, and the thick frost layer will block the air flow and affect the heating capacity of the air conditioner. Defrost. [0003] Existing air conditioners use the outdoor ambient temperature and the temperature of the outer pipe of the air conditioner to determine whether to defrost or not. For some air conditioners without an outdoor environmental temperature sensing device, only timed defrosting or fixed value of the outer pipe temperature can be used. Defrost is carried out by the method of frost, which is prone to frequent defrosting, and even frost-free defrosting, which seriously affects the...
