Problems solved by technology

[0003] Although the above-mentioned defrosting method can remove the frost on the outer surface of the outdoor heat exchanger, problems may arise in the case of a surrounding grille around the outdoor heat exchanger, for example, due to the heat exchange between the grille and the outdoor heat exchanger. The improper design of the distance between the surface of the heat exchanger or the deviation caused by the installation makes the frost on the surface of the outdoor heat exchanger spread to the enclosure, resulting in unclean defrosting

Abstract

The invention discloses a defrosting control method for an air conditioner. The defrosting control method includes the steps that when the air conditioner enters a defrosting mode, outdoor environment temperature and outdoor environment humidity are obtained; whether the outdoor environment temperature and the outdoor environment humidity meet preset conditions is judged; if yes, an outdoor fan is controlled to rotate reversely according to the pipe temperature and defrosting time of an outdoor heat exchanger so that defrosting can be performed on an enclosure net cover of the outdoor heat exchanger. According to the control method, residual frost on the enclosure net cover of the outdoor heat exchanger can be effectively cleared away. The invention further discloses a defrosting control device for the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and an air conditioner defrosting control device. Background technique [0002] In related technologies, the control method based on temperature and time is mainly used to realize the defrosting control of the air conditioner, that is, in the heating condition, when the tube wall temperature (tube temperature for short) of the outdoor heat When the value and the time condition are met, the air conditioner is controlled to enter the defrosting mode; when the tube temperature of the outdoor heat exchanger rises to a certain value or the time condition is met, the defrosting mode is exited and the heating mode resumes. [0003] Although the above-mentioned defrosting method can remove the frost on the outer surface of the outdoor heat exchanger, there may be problems in the case of a fence around the outdoor heat exchanger, for e...
