Fixed frequency air conditioner defrosting control method and computer storage medium

Abstract

The invention provides a fixed frequency air conditioner defrosting control method and a computer storage medium. The fixed frequency air conditioner defrosting control method comprises the steps thatwhether a fixed frequency air conditioner meets preset defrosting conditions or not is judged; if yes, the rotating speed of an internal fan of the fixed frequency air conditioner is obtained, wherein the rotating speed of the internal fan can be a high speed, a medium speed and a low speed; the defrosting duration is determined according to the rotating speed of the internal fan; and a defrosting device of the fixed frequency air conditioner is controlled to perform defrosting according to the determined defrosting duration. By means of the scheme, since the frosting situation of a heat exchanger is closely linked to the rotating speed of the internal fan in the fixed frequency air conditioner heating operating process, the defrosting duration is determined according to the rotating speed of the internal fan when the fixed frequency air conditioner meets the preset defrosting conditions, it can be guaranteed that defrosting of the fixed frequency air conditioner is timely and thorough, and in addition, energy wasting is reduced.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a defrosting control method and a computer storage medium for a fixed-frequency air conditioner. Background technique [0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the ambient temperature is too high or too low. Current air conditioner regulating devices mainly include various types of air conditioners and fans.

AI Technical Summary

Problems solved by technology

[0003] The current fixed-frequency air conditioner is difficult to identify the outdoor environment, especially in the process of heating and defrosting, it is difficult to accurately judge the frosting of the condenser, so the following situations often occur: there is no frosting but the frosting is misjudged, and thus Enter false defrosting; or the defrosting is incomplete, and there is still frost but quit defrosting, resulting in the accumulation of frost and affecting the subsequent heating effect

In addition, the defrosting time of fixed-frequency air conditioners is often fixed, but the operating conditions of fixed-frequency air conditioners are complex and changing. The fixed defrosting time will also lead to incomplete defrosting, and the remaining frost will stop or the defrosting has been completed, but the defrosting device continues to defrost because the fixed time has not been reached, resulting in energy waste
