The invention discloses an air conditioning system. The air conditioning system comprises a plurality of outdoor units, and at least one compressor is arranged in each outdoor unit. The air conditioning system further comprises a cloud control platform, and the cloud control platform is configured to obtain the accumulated operation duration of the compressor in each outdoor unit, and generate a module number table according to the accumulated operation duration of the compressor in each outdoor unit; one or more target action outdoor units matched with the current air conditioner load are determined according to the rotation sequence corresponding to the module number table; and after the target action outdoor units are determined, the instruction operation frequency of each target action outdoor unit is allocated according to the target calculation frequency. According to the air conditioning system, the operation time of each compressor in the outdoor units can be balanced, the selection of the target action outdoor units is determined and controlled by the cloud control platform, and the instruction operation frequency required to be executed by each target action outdoor unit is analyzed. Accurate control of each compressor is fully realized through a data model, and the bottleneck that a local controller can only cope with a simple algorithm is solved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning system. Background technique [0002] In the field of central air-conditioning systems, multiple units have become the main direction of industry development. Due to its convenient management and good energy-saving features, multi-connectors are favored in the market, especially in small and medium-sized projects, data centers, rail transit and other market segments, occupying a large market share. Compared with the traditional chiller central air conditioner, the multi-split unit saves the equipment such as the main engine room, cooling tower, water circulation system, etc., and the multi-split unit can be controlled individually or in groups, and can achieve ideal under different load conditions. operating efficiency. [0003] The multi-split unit has the advantages of being flexible and can achieve precise adjustment. The primary fact...
