Abstract

The invention relates to a multi-online system, a control method, device and equipment of the multi-online system and a storage medium. The control method comprises the steps that when an operation load of the multi-online system in the refrigeration process is less than a preset load, whether operation information of the multi-online system meets a preset anti-condensation condition or not is judged; if the operation information of the multi-online system meets the preset anti-condensation condition, all temperature alteration ratio of refrigeration space and the operation duration of an existing operating indoor machine in the multi-online system are obtained; whether the condensation risk exists in the existing operating indoor machine or not is judged according to the all temperature alteration ratio of the refrigeration space and the operation duration of an existing operating indoor machine; and if the condensation risk exists in the existing operating indoor machine, operating parameters of the existing operating indoor machine are adjusted according to a preset anti-condensation adjustment rule, when the operating load of the multi-online system is less than the preset load, the condensation risk of the existing operating indoor machine in the multi-online system is reduced.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a multi-connected system and its control method, device, equipment and storage medium. Background technique [0002] The multi-connection system has been more and more widely used in public places such as shopping malls, hotels, and office buildings. Usually, the multi-connection system has a large installed capacity and a large degree of freedom in design and installation. In actual use, any number of indoor units can also be opened freely. use. [0003] However, since the capacity of the outdoor unit of the multi-connected system is usually ten times or even dozens of times that of the smallest indoor unit, when only one or two small-capacity indoor units are running in the multi-connected system, the compression of the outdoor unit usually The output of the unit is much greater than the cooling demand of the indoor unit, and the indoor unit is prone to conden...
