Abstract

The invention discloses a defrosting control method and device of an air conditioner, and belongs to the technical field of air conditioners. The control method comprises the following steps that thetemperature of an inner coil pipe, indoor environment temperature and the rotating speed of an inner fan when the air conditioner operates are obtained; according to the temperature difference value and the rotating speed of the inner fan, a corresponding pre-judged working condition is matched from a preset correlation relationship, wherein the temperature difference value is the difference valuebetween the temperature of the inner coil pipe and the indoor environment temperature, the correlation relationship is used for representing the corresponding relationship among the temperature difference value obtained according to a pre-experiment, the wind speed of the inner fan and the pre-judged working condition, and the pre-judged working condition at least comprises a frosting working condition and a non-frosting working condition; and the air conditioner is controlled to switch to the defrosting mode in response to the matching result in the frosting working condition. The judgment control process of the defrosting control method does not depend on outdoor environment parameters, the defrosting process control can be realized only through operating parameters of an indoor unit, the intelligence of air conditioner control is improved, and the extra production cost caused by the arrangement of an 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...
