机械循环下供下回水平双管供暖系统的应用

Application of Down Feed Two Pipe Horizontal Cascade Heating System in Mechanical Circulation

分析了下供下回水平双管系统的优点以及自然循环作用压力的影响程度,计算数据证明下供下回水平双管系统的垂直热力失调基本不存在;因为每层供回水采用双管系统,所以也不存在距离热源最远的散热器不热问题。通过工程实例证明该系统供暖效果很好。

This paper analyses the advantages of down feed two pipe horizontal cascade system in all aspects and influencing degree by natural circulation pressure.The calculation results illustrate that there is almost no vertical heat maladjustment in down feed two pipe horizontal cascade system.Because the two pipe system is used for every storys giving and returning water,there is no problem with no heating at main lines farest terminal radiator in horizontal giving water branch.This paper solves problem well in giving off air in down feed two pipe horizontal cascade system.Application of this system in buildings shows good heating effect.
