Research on design method of low energy consumption chilled water system based on PIPE-FLO

For the air conditioning chilled water system, a parametric design method based on the simulation software PIPE-FLO of fluid transmission and distribution pipeline network is proposed. Combined with the flow-resistance characteristics of the equipment, the simulation model of the system pipe network is built, and the design parameters such as the temperature difference of the supply and return water, the equipment resistance and pipe diameter of the chilled water system are dynamically adjusted on the basis of ensuring the hydraulic balance, so as to realize the purpose of optimal selection of water pump and reduction of energy consumption of water system transmission and distribution. The analysis of engineering examples shows that the parametric design method has good technical and economic performance.
