本文提出一般民用建筑采暖设计应计算支、立管的散热。计算表明,支、立管有效散热量大致为建筑耗热量的30%。如不计算这个散热量,将多装散热器,不仅浪费,而且会引起垂直失调。“楼层修正”不能解决这个问题。文中还给出计算支、立管散热量的简化方法。
This article proposes that general civil building heating design should calculate the heat dissipation of the branch and riser. The calculation shows that the effective heat dissipation of the branch and riser is approximately 30% of the heat consumption of the building. If you do not calculate this amount of heat, installing more radiators will not only waste but also cause vertical misadjustment. “floor correction” cannot solve this problem. The paper also gives a simplified method to calculate the heat dissipation of the branch and riser.
