地板遮盖对地板辐射供暖影响的研究

介绍了低温热水地板辐射采暖系统的优点和工程设计的一般方法。由于地板辐射采暖与传统的对流换热采暖的机理不同，所以在设计中存在认识上的一些问题，导致了实际应用中低温热水地板辐射采暖系统的散热量与设计热负荷不符。本文结合设计规范中已有的公式计算得出低温热水地板辐射采暖系统的辐射散热量在允许的各地板表面平均温度tb和室内设计温度tn下所占的比例以及地板遮挡面积对房间采用低温热水地板辐射采暖系统时造成的散热量的降低．时低温热水地板辐射粟嗜系统设计中因地板遮挡面积引起的散热量损失有所拳孝。

Influence of sheltered floor on floor radiation heating system

Low temperature floor radiation heating system and the general design methods in programs are introduced.As the theory of the floor radiance heating system is different from the one of convective heat transfer,some proldems exist in cognition leading to the inconsistency of heat dissipation between practice and design of the low temperature floor radiance heating systen.Combined with formula existed in criterion,the ratio and the reduction of radiation heat dissipation of low temperature floor radiance heating system was worked out in different allowed floor surface average temperature tb and different indoor designed temperature tn,further more in shelter condition emphatically.It is reference to amount loss by sheltered floor area of low temperature floor radiation heating system design.
