Abstract


This article has conducted the related research in view of the approach of hydraulic balance of air-conditioning water system. Firstly analyzed the calculation of air conditioning water system, which discussed the relationship between the specific parameters of pressure, flow and impedance, and analyzed the characteristics of the flow, the flow coefficient and the valve authority of control valve; then elaborated on the theory and of balancing valve and lay the theoretical basis for research; hen proposed the relevant calculation principles of hydraulic balance, calculated the hydraulic balance of water system in operating condition; then set up reverse return system and apply balancing control valve to get its balance, according to the results of hydraulic balance and properties of balancing control valve, in the water system calculated to choose static balance valve, dynamic differential balancing valve, dynamic electric balancing valve, to achieve dynamic equilibrium The hydraulic system balance, respectively, then determined their location, type and the relevant parameters, thereby achieve a total hydraulic balance; finally adopted the research approach to explain elaborately their application by the example of the Shopping Centre of Changchun City, and made the whole water system to achieve total hydraulic balance.
