The invention discloses an automatic adjustment method and
system for hydraulic balance of a central air-conditioning
system. According to the adjustment method, the requirements are achieved throughthe grading adjustment and adjustment of the
flow ratio of each pipeline, the tedious steps of conventional manual hydraulic balance adjustment are simplified, and the manual expenditure for the adjustment of the hydraulic balance of an air conditioner is saved for a proprietor; and in addition, the hydraulic imbalance phenomenon of an air conditioner water
system is avoided, the problem of complaints of tenants due to uneven heat and cold of the air conditioner
tail end is solved, and a key effect is achieved for
energy conservation of air conditioner operation of the proprietor. According tothe adjustment system, the
flow ratio of the pipeline is calculated through flow meters on the pipelines and transmitted the
flow ratio to a centralized controller, and the centralized controller processes, analyzes and controls adjusting valves of the pipelines to adjust the
water flow of the pipelines, so that the flow ratio of the pipelines meets the requirement, and hydraulic balance of the centralized air conditioner water system is achieved. Meanwhile, the flow meters can display and transmit the flow ratio of the pipeline flow of the air conditioner water system, and the problem that an existing pipeline flow meter of the air conditioner water system cannot display the flow ratio is solved.
