METHOD, DEVICE, AND SYSTEM FOR CONTROLLING COLD-WATER MAIN UNIT OF CENTRAL AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/210807
Kind Code:
A1
Abstract:
Provided in the present disclosure are a method, device, and system for controlling a cold-water main unit of a central air conditioning system. The method comprises: acquiring the total cooling load of a central air conditioning system; determining a target cold-water main unit combination on the basis of the total cooling load, and determining operating parameters corresponding to target cold-water main units in the target cold-water main unit combination on the basis of the total cooling load; controlling the target cold-water main units in the target cold-water main unit combination to perform cooling with the corresponding operating parameters of each. The present disclosure implements the direct starting of the cold-water combination in an optimal combination suitable for the actual cooling load of a building when starting the units, improves a smart control effect of the optimization control of the central air conditioning system and system stability, and maximizes the performance utilization of the central air conditioning system.
