WIPO Patent Application WO/2024/046434
Kind Code:
A1
Abstract:
Provided are a water-chilling unit air-conditioning system and a control method therefor. The water-chilling unit air-conditioning system comprises a plurality of water-chilling units and a controller. The controller is configured to: establish a performance model of the water-chilling units; and calculate target parameters of each water-chilling unit among the plurality of water chilling units under a plurality of working conditions, wherein the plurality of working conditions are different from each other, and the number of turned-on water-chilling units among the plurality of water-chilling units is different under the plurality of working conditions; calculate a predicted energy efficiency ratio of each water-chilling unit according to the performance model of the water-chilling units and at least one of the target parameters of each water-chilling unit; and determine the operation states of the plurality of water-chilling units according to the predicted energy efficiency ratio of each water-chilling unit.
