Abstract

The invention discloses a defrosting control method and device for an air conditioner. The method comprises the following steps: outdoor environment information is obtained, and the outdoor environment information at least comprises outdoor environment temperature and humidity; the outer pipe temperature information of a condenser is obtained, and the outer pipe temperature information at least comprises an outer pipe temperature value and a temperature change speed of the condenser; the outdoor environment information and the outer pipe temperature information are input into a neural networkmodel for calculation, and whether the air conditioner needs to be controlled to enter a defrosting mode or not is judged; and if the air conditioner needs to be controlled to enter the defrosting mode, defrosting control is carried out on the air conditioner according to a defrosting duration output by the neural network model. Through the defrosting control method and device for the air conditioner, the problem that defrosting control over an air conditioner is inaccurate in the related technology, is solved.

Description

technical field

[0001] The present application relates to the technical field of air conditioners, in particular, to an air conditioner defrosting control method and device. Background technique

[0002] When the outdoor temperature is low, frost will appear on the condenser and affect the performance of the air conditioner, so defrosting control is often required. However, the defrosting time of the existing air conditioner is often simply judged based on the temperature of the outer tube and the operating time, which is difficult Precise control is carried out according to the actual frosting of the external unit, which may cause unclean defrosting or too long defrosting, which will affect the comfort of users. Therefore, it is very important to accurately control the defrosting time.

[0003] The first related technology can ensure clean defrosting after multiple defrosting, but it has not optimized the situation that the defrosting time is too long.
