摘要
基于流体力学一元流动连续方程、能量方程及串并联管路流动规律,建立了冷冻水系统的简化模型,推导出适合于计算一般大厦冷冻水系统阻抗的并联计算法.并利用某大厦冷冻水系统的已知运行参数进行了实例计算,所得循环压力结果与实测值相吻合,表明并联计算法可行.
Based on continuity equation,energy equation and fluid principle of parallel series pipe system of one-dimensional flow,a parallel calculating method applied to calculate resistance of chilled water system in common high buildings is derived with a simplified model of chilled water system.As to real examples calculations are made by using given operating parameters of a certain building′s chilled water system,and the results of circulating pressure are obtaind which are in good accordance with actually measured values,showing the feasibility of the method proposed.
