摘要:

根据某地区集中供热管网的特点,分别介绍了枝状管网和环状管网的水力计算方法。通过水力计算分别得到供热管网在枝状运行工况和环状运行工况下的循环阻力,并对不同工况下的供热管网循环阻力进行比较,指出特定条件下环状管网在运行能耗和可靠性方面相对于枝状管网的优越性,具有一定的推广应用价值。

Abstract:

Based on the centralized heat supply system of a certain area, the hydraulic calculation method for dendritic and ring pipeline was introduced. Circulating resistance of dendritic and ring pipeline was calculated and compared based on different work condition. It was indicated that ring pipeline take advantages than dendritic pipeline on operation energy consumption and reliability in certain work condition. Which has certain value for promotion and implementation.
