Title:
ENERGY-SAVING CONTROL METHOD, SYSTEM AND DEVICE FOR WATER CHILLING UNIT OF CENTRAL AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/213494
Kind Code:
A1
Abstract:
Provided in the present invention are an energy-saving control method, system and device for a water chilling unit of a central air conditioner. The method comprises: performing, within a safe range, a heuristic operation and/or a fine adjustment operation on parameters that comprise three types of parameters, namely the number and gears of cooling tower fans that are turned on, the number of cooling tower water pumps that are turned on, and a chilled water supply temperature setting; after each heuristic operation and/or fine adjustment operation, calculating the overall energy consumption of a water chilling unit and a cooling tower; and taking a combination of operation parameters with the lowest energy consumption and corresponding basic working conditions and energy consumption within a unit time as operation knowledge and learning parameters, and recording same in a database. By means of the present invention, overall learning is performed on running parameters of a water chilling unit and a cooling tower, and heuristic fine adjustment is performed within a safe operation range, so as to search for the most energy-saving control method, such that energy saving performance of an air conditioner main unit is further improved.
