Abstract

The invention provides a defrosting control method and device, a storage medium and an air conditioner. The method comprises the steps that when the air conditioner works in the heating mode, whetherthe air conditioner needs to be defrosted or not is detected; if yes, according to whether the running frequency of the compressor is larger than the first reserved frequency or not, execution of first defrosting operation or second defrosting operation is determined. According to the scheme, the air conditioner is controlled to be in the defrosting mode to carry out running, different switching manners are adopted, and the aims that in the air conditioner unit defrosting process, the switching speed is high, the switching noise is low, the defrosting period is short, and the user comfort is improved.

Description

technical field [0001] The invention relates to the control field, in particular to a defrosting control method, device, storage medium and air conditioner. Background technique [0002] In a conventional heat pump air conditioner, when the heating operation time is long in a low temperature and humid environment, the outer heat exchanger is prone to frosting, which will affect the heat transfer performance of the outer heat exchanger and reduce the heating effect of the air conditioner. The air conditioning unit switches to the defrosting cycle mode to defrost the outer heat exchanger. However, during the defrosting period, the air conditioning unit will stop heating, and there will even be cold wind blowing out, resulting in temperature fluctuations inside the environment, especially in environments with small interior spaces such as cars, the temperature fluctuations are more obvious, which seriously affects the comfort of users , so the defrosting time of the air condit...
