Air conditioner defrosting control method, device and air conditioner

Abstract

The present application relates to an air conditioner defrosting control method, device and air conditioner. The control method includes: when the defrosting process performed by the air conditioner is completed, acquiring the defrosting duration of the defrosting process executed by the air conditioner; based on the defrosting duration of the defrosting process executed by the air conditioner, the The defrosting interval between the defrosting process and the next defrosting process is corrected; when the defrosting interval is determined to meet the interval length condition based on the corrected defrosting interval, the air conditioner is controlled to trigger the next defrosting Process defrosting judgment. The air conditioner defrosting control method provided by the embodiments of the present disclosure can reduce the limitation of the air conditioner defrosting function and the failure to trigger the defrosting in time due to the use of a fixed defrosting time interval in the prior art to control whether the air conditioner enables the defrosting function. Functional problems, to achieve a more precise control of the air conditioner defrosting function.

Description

technical field [0001] The present application relates to the technical field of air conditioner defrosting, for example, to an air conditioner and a method for controlling the defrosting thereof. Background technique [0002] With the improvement of people's living standards, air-conditioning equipment has also entered thousands of households. The use of household air conditioners and central air conditioners is becoming more and more common. Users have higher and higher requirements for the comfort of air conditioners. Some problems have gradually come out, one of which is the problem of frost and freezing of the outdoor unit when the air conditioner is running in severe cold weather. When the air conditioner is running in a low-temperature region or a region with strong wind and snow, the condensed water on the outer surface of the condenser of the outdoor unit will drip onto the chassis. If there is icing problem, the condensed ice layer on the outdoor unit will hinder ...

AI Technical Summary

Problems solved by technology

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: In order to avoid the problem that the air conditioner continuously and frequently activates the defrosting function in a low-temperature environment and affects the normal heating work in the related art, generally the air conditioner is set to After the defrosting is completed, the defrosting function will not be activated within a fixed period of time, such as setting the defrosting time interval of 20 minutes or 30 minutes; the disadvantage of this method is that the factors that affect the frosting degree of the air conditioner outdoor unit include not only the external environment Factors, including factors affecting the state of the air conditioner itself, since the working status of each component of the air conditioner will change after each defrosting is completed, if you still use this fixed defrosting time interval to control whether the air conditioner enables the defrosting function , there will actually be a large error with the actual frosting state of the air conditioner. For example, in extremely cold weather, if the defrosting time interval is set for a long time, then the air conditioner will easily fall within the time period of the defrosting time interval. A lot of frost condenses, and at this time, the air conditioner will not immediately activate the defrosting function due to the limitation of the defrosting time interval, which will affect the normal use of the air conditioner
