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 includes the steps that inner coil temperature and the inner fan rotating speed during air conditioning operation are obtained, and the decay rate of the inner coil temperature is determined; and according to preset incidence relation, thedecay rate of the inner coil temperature and the inner fan rotating speed, the defrosting duration of a defrosting mode performed by the air conditioner is determined, and the incidence relation is used for representing the corresponding relation between the decay rate, the inner fan rotating speed and the defrosting duration. According to the provided defrosting control method of the air conditioner, the duration of the defrosting mode performed by the air conditioner can be determined according to the decay rate of the inner coil temperature and the inner fan rotating speed, and thus when the possibility of air conditioning frosting problem is determined to exist, the air conditioner can be controlled in time to defrost an outdoor unit with the determined defrosting duration; and determination of the defrosting duration of the defrosting control method does not depend on outdoor environment parameters, defrosting process control can be realized only through operating parameters of an indoor unit, and intelligence of air conditioning control is improved.
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...
