Air conditioner defrosting control method and device, electronic equipment and storage medium

Abstract

The invention provides an air conditioner defrosting control method and device, electronic equipment and a storage medium, and relates to the technical field of air conditioners. The air conditioner defrosting control method comprises the steps of continuously obtaining pipe temperatures of an outdoor unit heat exchanger and an indoor unit heat exchanger at the interval of a preset period, so that a plurality of first temperatures and a plurality of second temperatures are obtained; calculating change rates of the multiple first temperatures corresponding to a plurality of preset periods, so that a plurality of first temperature change rates are obtained; calculating change rates of the multiple second temperatures corresponding to the multiple preset periods, so that a plurality of second temperature change rates are obtained; calculating a plurality of first change deviations according to the multiple first temperature change rates; calculating a plurality of second change deviations according to the multiple second temperature change rates; and controlling an air conditioner to enter a defrosting mode according to the multiple second temperatures, the first temperature change rates, the second temperature change rates, the first change deviations and the second change deviations. According to the air conditioner defrosting control method provided by the invention, the air conditioner can be prevented from entering the defrosting mode frequently, and the heating comfort of the air conditioner is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method, device, electronic equipment and storage medium. Background technique [0002] When the air conditioner is heating in winter, due to the low outdoor temperature, after the air exchanges heat with the heat exchanger of the low-temperature outdoor unit of the air conditioner, condensed water is generated and stays on the fins. When the evaporating temperature is lower than 0°C, the condensed water begins to frost, causing the condenser to gradually frost, which affects the heat exchange efficiency of the heat exchanger. [0003] At present, the air conditioners on the market usually judge whether to defrost according to the detected fin temperature. This kind of judgment is based on a single basis, which often leads to the short heating time of the air conditioner and frequently enters the defrosting mode, which serious...

When the evaporating temperature is lower than 0°C, the condensed water begins to frost, causing the condenser to gradually frost and affecting the heat exchange efficiency of the heat exchanger

[0003] At present, the air conditioners on the market usually judge whether to defrost according to the detected fin temperature. This kind of judgment is based on a single basis, which often leads to the short heating time of the air conditioner and frequently enters the defrosting mode, which seriously affects the heating comfort. influences
