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 a first time parameter associated with the current frosting state and a second time parameter associated with the historical frosting state of the air conditioner; based on the first time associated with the current frosting state parameter and the second time parameter associated with the historical frosting state, the defrosting interval between this defrosting process and the next defrosting process is corrected; the satisfying interval is determined based on the corrected defrosting interval condition, control the air conditioner to make a defrost judgment whether to trigger the next defrost process. The air conditioner defrosting control method provided by the embodiments of the present disclosure realizes more precise control of the air conditioner defrosting function.

Description

Technical field [0001] The present application relates to the technical field of air conditioning defrosting, for example, to a control method of air conditioning and defrosting thereof. Background [0002] With the improvement of people's living standards, air conditioning equipment has also entered thousands of households, the use of household air conditioning, central air conditioning is more and more common, users' requirements for air conditioning comfort are getting higher and higher, and the problems existing in the use of air conditioning are gradually leaking out, one of which is the problem of outdoor unit frost freezing when air conditioning is running in a cold climate. In the air conditioner in the low temperature area or the wind and snow in the area of larger operation, the external surface of the condenser of the outdoor unit condensed water flow will drip on the chassis, the air conditioner for a long time running, will lead to the air conditioner condenser and c...

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
