[0026] see figure 1 , which is a schematic flowchart of an air conditioner defrosting control method provided in the first embodiment of the present invention. The air conditioner defrosting control method, for example, includes the following steps:

[0027] First, the air conditioner is controlled to enter the defrosting mode, and the defrosting time t of the air conditioner is acquired.

[0028] Wherein, the defrosting duration of the air conditioner can be obtained through a preset timer. For example, when the air conditioner enters the defrosting mode, the timer is started to count; when the air conditioner exits the defrosting mode, the timer is stopped.

[0029] Secondly, it is judged whether the defrosting time t of the air conditioner is less than the longest defrosting time t of the air conditioner under the low temperature condition 0 ; If td Judging whether the air conditioner exits the defrosting mode; if t≥t0, then controlling the air conditioner to exit the de...

Abstract

The embodiment of the invention provides an air conditioner defrosting control method. The air conditioner defrosting control method comprises the steps that an air conditioner is controlled to enter a defrosting mode, and the defrosting duration t of the air conditioner is obtained; whether the defrosting duration t meets a first defrosting exiting condition or not is judged; and if yes, the air conditioner is controlled to exit the defrosting mode, wherein the first defrosting exiting condition is that t is larger than or equal to t0, and t0 is the longest defrosting duration under the low-temperature working condition of the air conditioner. According to the air conditioner defrosting control method, the technical problem that the heating effect is poor when a chassis of an air conditioner outdoor unit accumulatively freezes is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method. Background technique [0002] After the air conditioner enters the defrosting mode, the air conditioner changes from heating operation to cooling operation. At this time, the external unit of the air conditioner absorbs heat for the condenser and melts the frost on the surface of the outer coil into water, which is passed through the water outlet on the chassis of the external unit of the air conditioner. hole to drain it. However, if the water on the chassis is not drained, the undrained water will accumulate and freeze on the chassis, resulting in incomplete defrosting of the external unit of the air conditioner, reducing the heating effect of the air conditioner and the comfort of the air conditioner. Contents of the invention [0003] In order to solve the problem of poor heating effect when the chassis of the air cond...
