Multi-split air conditioner, cleaning method of multi-split air conditioner, control device and readable storage medium

Abstract

The invention discloses a cleaning method for a multi-split air conditioner, which comprises the following steps of: controlling the multi-split air conditioner to refrigerate so as to frost a target indoor unit; the target indoor unit is an indoor unit which receives a cleaning instruction in the at least two indoor units; heating operation of the multi-split air conditioner is controlled, so that the target indoor unit is defrosted; and when defrosting of the target indoor unit is completed, the multi-split air conditioner is controlled to maintain heating operation, and the operation frequency of a compressor is adjusted so that the temperature of the target indoor unit can reach the target sterilization temperature. The invention further discloses an air conditioner control device, the multi-split air conditioner and a computer readable storage medium. The indoor unit can be subjected to high-temperature sterilization after being cleaned, the cleaning effect is improved, and it is guaranteed that air obtained after heat exchange of the indoor unit can ensure the health of indoor users.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a cleaning method of a multi-line air conditioner, an air conditioner control device, a multi-line air conditioner and a computer-readable storage medium. Background technique [0002] Multi-line air conditioners refer to air conditioners with multiple indoor units. Most of the multi-line air conditioners have a self-cleaning function, which generally includes two stages of refrigeration frosting and heating defrosting. The condensed frost will be melted by heating and defrosting, so that the dirt will flow away with the defrosting water to realize the cleaning of the indoor unit. [0003] However, at present, the multi-connected air conditioners are not sterilized after cleaning, and bacteria are likely to remain in the indoor unit. The air passing through the heat exchange of the indoor unit carries bacteria, which has the problem of poor cleaning effect a...

Problems solved by technology

[0003] However, at present, multi-connected air conditioners are not sterilized after cleaning, and bacteria are likely to remain in the indoor unit. The air that has been heated by the indoor unit carries bacteria, and the cleaning effect is not good, which affects the health of indoor users.
