Abstract

The invention discloses a defrosting control method and device for an air conditioner, and belongs to the technical field of air conditioners. The control method comprises the following steps: the temperature of an inner coiled pipe and the rotational speed of an inner fan during the running of the air conditioner are obtained, and an outer server is queried to obtain outdoor environment parameters; matching is carried out in a preset association relationship according to the temperature of the inner coiled pipe, the wind speed of the inner fan, and the outdoor environment parameters to obtaina corresponding pre-judgement working condition, the association relationship is used for representing a corresponding relationship among the temperature of the inner coiled pipe, the wind speed of the inner fan, the outdoor environment parameters, and the pre-judgement working condition, which is obtained according to an in-advance experiment, wherein the pre-judgement working condition at leastcomprises a frosting working condition and a non-frosting working condition; and the air conditioner is controlled to be switched over to a defrosting mode in a manner of corresponding to a matchingresult in the frosting working condition. The judgement control process of the defrosting control method is capable of realizing defrosting process control without dependence on an outdoor unit sensor, so that the intelligence of air conditioner control is improved, and the additional production cost caused by configuration for the outdoor sensor is avoided.

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. 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. [0003] 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 the heat exchange between...
