Problems solved by technology
[0004] In the process of realizing the embodiments of the present disclosure, it is found that there are at least the following problems in related technologies: air conditioners generally use the dew point temperature calculated from the outer ambient temperature parameters as the frost point temperature, and since most outdoor units are not equipped with humidity sensors, the detection can be used to accurately calculate the dew point The temperature and humidity parameters and the working status of each component of the air conditioner will also change after each defrosting is completed. Therefore, the frost point temperature determined by this method has a large error with the actual working condition, and it cannot satisfy the precise control of the air conditioner to trigger defrosting.

The present application relates to a control method and device for defrosting an air conditioner, and an air conditioner. The control method includes: when the air conditioner has completed the defrosting process, acquiring a first time parameter associated with a current frosting state and a second time parameter associated with a historical frosting state of the air conditioner; based on the associated current frosting state The first time parameter and the second time parameter associated with the historical frosting state correct the frost point temperature; based on the corrected frost point temperature, the air conditioner is controlled to determine whether to trigger the next defrosting process. The defrosting control method for an air conditioner provided by the embodiments of the present disclosure can reduce the large error between the frost point temperature and the actual working condition caused by the use of the dew point temperature to determine the frost point temperature and the change of the working state of the air conditioner's own components, and the triggering of the defrosting process in the prior art. The problem of inaccuracy has achieved more precise control of the defrosting function of the air conditioner.
Description
technical field [0001] The present application relates to the technical field of air conditioner defrosting, for example, to an air conditioner and a defrosting control method thereof. Background technique [0002] With the improvement of people's living standards, air-conditioning equipment has entered thousands of households. One of the problems is that the outdoor unit of the air conditioner is frosted and frozen when the air conditioner is operating in a severe cold climate. When the air conditioner operates in a low temperature area or an area with strong wind and snow, the water condensed on the outer surface of the condenser of the outdoor unit will drip onto the chassis. When the air conditioner is running for a long time, the condenser and chassis of the air conditioner will be damaged. When there is an icing problem, the ice layer condensed on the outdoor unit will hinder the heat exchange between the internal refrigerant and the outdoor environment, which will re...
