四种供暖末端形式下及舒适性的比较

Comparison of Exergy and Comfort Under the Four End Conditions

对四种供热末端形式下单位面积的耗炯量及节能率进行了分析与比较,得出毛细管顶板辐射供热耗能量最少,最节能环保;通过airpak软件对室内的热环境进行了模拟,分别得出室内供热房间的温度云图、PMV云图,并进行了分析与比较得出结论:地板辐射供暖在经过人体的截面处温度梯度小于毛细管顶板辐射供热,不会产生"辐射吹风感",人体感觉更舒适。

In this paper, the energy consumption and the energy saving rate of the unit area under the four terminal forms are analyzed and compared,it is concluded that the capillary ceiling radiant heating energy consumption is the least, and the most energy saving and environmental protection.The indoor thermal environment is simulated by the Airpak software.Respectively, temperature contours, PMV nephogram were obtained, and analyzed and compared to draw the conclusion： temperature gradient under floor radiant heating in the cross section of the human body is less than the capillary ceiling radiation heating and will not produce radiation hair feeling, the human body feel more comfortable.
