Problems solved by technology

In the prior art, the air conditioner often adopts timing defrosting control, the defrosting cycle is too short, so that frequent defrosting will affect the heating effect of the air conditioner when the frosting condition is not reached, and the defrosting cycle is too long, it will be difficult to defrost in time
[0003] The disadvantage of the above technical solution is that it is difficult for the air conditioner to achieve reasonable defrosting control with the timing defrosting technology

Abstract

The invention discloses an air conditioner defrosting control method, an air conditioner and a computer-readable memory medium. The air conditioner defrosting control method comprises the following steps: acquiring the relative humidity of the current outdoor environment, the temperature of the current outdoor environment and the temperature of a current outdoor heat exchanger; detecting the continuous operating time of the air conditioner under the relative humidity condition in the current outdoor environment; according to the relative humidity of the current outdoor environment, the temperature of the current outdoor environment, the temperature of the current outdoor heat exchanger and the continuous operating time, judging whether the outdoor heat exchanger meets the preset defrosting condition or not; if the outdoor heat exchanger meets the preset frosting condition, performing defrosting operation on the outdoor heat exchanger. According to the air conditioner defrosting control method, the air conditioner and the computer-readable memory medium, reasonable defrosting control over the air conditioner is realized.

Description

technical field [0001] The present invention relates to the technical field of air conditioner defrosting, in particular to an air conditioner defrosting control method, an air conditioner and a computer-readable storage medium. Background technique [0002] An air conditioner is a widely used refrigeration or heating device. In the prior art, when the air conditioner operates in a low-temperature heating mode, it is often accompanied by frosting on an outdoor heat exchanger. Once the outdoor heat exchanger is frosted, it will reduce the heat exchange efficiency of the air conditioning system and hinder the improvement of the heating capacity of the air conditioner. In order to solve the capacity attenuation problem of the air conditioner after frosting, it is necessary to switch the air conditioner to the defrosting mode. In the prior art, the air conditioner is often controlled by timed defrosting. If the defrosting cycle is too short, frequent defrosting will affect the ...
