地板辐射板面积及位置对采暖房间的影响

Different Area and Position of Floor Heating Influence on Heating Room

本文介绍了采用吸收系数法建立辐射采暖房间换热模型的方法,并根据该方法编制相应计算程序对室外温度为-26℃时,分别对普通采暖房间、山墙采暖房间,当地板辐射板的安装面积以及铺设位置不同时,房间的采暖能耗及热环境进行计算机模拟计算,证明对于普通采暖房间和山墙采暖房间,随地板辐射板面积的增加,房间的采暖能耗减小;地板辐射采暖板覆盖率很小时,其铺设位置不同对房间的能耗及热环境有影响,而当地板辐射板覆盖率很大时,其安装位置不同对能耗及热环境的影响很小。

In the thesis the author adopted method of absorption coefficient and established the model of heat transfer of the buildings. The corresponding computer program simulated the energy consumption and the change of temperature in the common rooms and gable wall rooms with different area and position of floor heating when the outdoor temperature is 26℃. The simulation shows, for the common and gable wall rooms, the energy consumption reduces with the increase of the occupying area of radiant floor heating, when the radiant floor heating area is comparatively small, its position has great influence on the energy consumption and the heat environment. But as the radiant floor heating area is getting larger, its position remains negligible to the energy consumption and heat area.
