Embodiment Construction

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] like figure 1 As shown, an embodiment of the present invention provides a defrosting control method, including the following steps: when an air conditioner operates in a heating mode, detecting a system current; Up and down trend; when the system current is less than the first reference current and the system current is in a downward trend, the air conditioner is controlled to enter a defrosting mode.

[0033] Specifically, in this embodiment, combined with image 3 As shown in the figure, when the air conditioner is running in the heating mode, the system current is detected. The system current refers to the motor current plus the compressor current. When frost occurs, the refrigerant on the evaporating side is not ful...

Abstract

The invention provides a defrosting control method and device, an air conditioner and a storage medium and relates to the technical field of air conditioners. The defrosting control method comprises the following steps that when the air conditioner operates in a heating mode, the system current is detected; the rising or falling trend of the system current is judged while the system current is compared with first reference current; and the air conditioner is controlled to operate in a defrosting mode when the system current is smaller than the first reference current and is in a falling trend.According to the defrosting control method and device, the air conditioner and the storage medium, the frosting and defrosting conditions are reflected by the system current variation conditions, thedefrosting mode is precisely controlled, deterioration of a frost layer of the outdoor side is effectively prevented, and the air conditioner heating stability is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a defrosting control method, device, air conditioner and storage medium. Background technique [0002] With the development of air-conditioning technology, comfort has become an indicator that people pay more and more attention to when purchasing air-conditioning. [0003] The defrosting process of the existing air conditioner includes detecting the frost formation on the outdoor side through a temperature sensor, and removing the frost layer before the outdoor side frost layer enters the deterioration period to avoid affecting the performance of the air conditioner, but when the temperature sensor is damaged, the air conditioner It will enter the timed forced defrosting mode, thus affecting the comfort of the air conditioner. Therefore, the control method of controlling the air conditioner entering and leaving the defrosting mode by detecting the temperatur...
