Abstract

The invention provides an air conditioner system, and a control method and device thereof, which is used for solving the air conditioner system in the prior art that each compressor is unbalanced to use. The method comprises the following steps of controlling each compressor to start according to the preset operation priority of the compressor; monitoring the operation situation of each compressor; resetting the operation priority of the compressor when the operation situation of the compressor reaches a preset compressor alternation condition; and controlling the compressor to operate according to the reset operation priority of the compressor. By adopting the technical scheme, each compressor of the air conditioner can be adequately utilized, the service life of the entire air conditioner can be prolonged, the daily maintenance cost can be reduced, and the working efficiency of the air conditioner system can be improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioning system and its control method and device. Background technique [0002] At present, for an air-conditioning system including multiple compressors, the existing air-conditioning system mainly sets a certain priority for each compressor according to the rated power of each compressor, and controls the system according to the priority of each compressor. Distribute the load to the compressor to achieve cooling or heating effect. [0003] According to the solution of the prior art, when the air-conditioning system operates under low-load conditions for a long time, the compressors with low priority cannot operate, while the compressors with high priority run for a long time, resulting in that the compressors of the air-conditioning system are not used properly. balanced, making maintenance difficult. Moreover, for an air-conditioning system with multiple outdoor ...
