热舒适性情况下的低温地板辐射供暖节能研究

The thermal comfort conditions of low-temperature radiant floor heating system energy saving research

通过对在舒适性温度范围内16℃～18℃、14℃～16℃进行低温地板辐射间歇供暖试验,测量了室外空气温度、室内各个测点的空气温度、地板表面温度、供回水温度及水流量,并与上班期间间歇供暖及全天连续供暖进行对比。结果表明,在满足热舒适性情况下间歇供暖,温度梯度变化小,使人的舒适感比传统间歇式供暖要好的同时,节能效果明显。未来西南地区冬季普遍供暖成为了一种趋势,本试验为西南地区冬季低温地板辐射间歇供暖运行研究提供了参考和依据。

Through the comfort temperature range of 16℃ -18℃, 14℃ -16℃ intermittent heating experiment of low-temperature floor radiation, the temperature of outdoor air, indoor air temperature of each measuring point, the floor surface temperature, supply and return water temperature and water flow are measured, and they are contrasted with the intermittent heating of work and continuous heating throughout the day. The results showed that, under the condition of thermal comfort of intermittent heating, small temperature gradient changes, the human comfort better than traditional intermittent heating at the same time, energy saving effect is obvious. Future universal heating in winter in the southwest has become a trend,the experiment provides reference and basis for the study of low-temperature floor radiation intermittent heating operation in the winter of southwest region.
