Abstract

The present invention proposes a multi-connected air conditioner and its control method. The multi-connected air conditioner includes a plurality of indoor units with heat exchangers. Each indoor unit includes a controller. The controller includes a processor and a memory, and the memory stores There is a computer program, and when the computer program is executed by the processor, the following steps can be realized: when one or more indoor units receive a self-cleaning instruction, detect whether there is an alarm in the multi-connected system, and detect whether the operation mode of other indoor units is It conflicts with the self-cleaning indoor unit operation mode. This control method is based on the multi-connected air conditioner described above. The plurality of indoor units of the invention can be any one or more of the self-cleaning modes at the same time, and the control method ensures that there is no operation conflict between the indoor unit performing self-cleaning and other indoor units, so that the multi-connected air conditioner run smoothly.

Description

technical field [0001] The invention belongs to the field of multi-connected air conditioners, in particular to the field of self-cleaning control of indoor units of multi-connected air conditioners. Background technique [0002] At present, with the improvement of people's living standards, multi-connected air conditioners have become very popular in the household market. Most of the multi-connected indoor units are embedded, but the embedded indoor units cannot be used for the heat exchanger of the indoor unit after a long period of use. Manual cleaning is performed, so self-cleaning technology is required to meet the needs of users. For the unit unit, there is only one indoor unit, and the self-cleaning is not affected by the control of other indoor units, and the sensor information is relatively small, but for the multi-connected unit, the self-cleaning process will be interfered by the control of other indoor units. It involves a lot of sensor information, and it will ...
