Abstract

The invention provides an air conditioner outdoor unit defrosting control method and device, a storage medium and an air conditioner, and relates to the technical field of air conditioners. The air conditioner outdoor unit defrosting control method comprises the following steps that outdoor temperature and outdoor humidity are acquired; an outdoor unit is controlled to execute a defrosting mode according to the outdoor temperature, the outdoor humidity and a preset humidity interval in which the outdoor humidity falls; and the defrosting mode comprises one or more of outer fan speed regulation, compressor frequency modulation and expansion valve opening degree regulation. According to the air conditioner outdoor unit defrosting control method and device, the storage medium and the air conditioner, whether the outdoor unit is controlled to defrost or not is determined through dual judgment conditions of the outdoor temperature and the outdoor humidity, on the premise that the outdoor side temperature and humidity are under certain conditions, the outdoor unit is defrosted to different degrees through different intervals of the outdoor humidity, the outdoor temperature and outdoor humidity factors are comprehensively considered, and the outdoor unit is prevented from frosting.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method, device, storage medium and air conditioner for an external unit of an air conditioner. Background technique [0002] In the prior art, the defrosting judgment for the outdoor unit mostly depends on the temperature of the external disk to determine whether to enter the defrosting program, for example, when the temperature of the external disk is less than or equal to the preset temperature, the defrosting program is started. In actual use, the humidity of the environment where the outdoor unit is located will have a greater impact on the frosting of the outdoor unit. When the humidity of the environment where the outdoor unit is located is higher, the frosting speed of the outdoor unit will be faster. Therefore, when the humidity of the environment where the outdoor unit is located is high, the speed of frosting will be accelerated, re...
