大换气量房间冬季室内热环境实测与分析

通过对顶棚辐射、散热器与热风三种采暖方式在大换气量情况下室内热状况的实测，对其热舒适性与节能效应进行了分析和讨论，指出辐射采暖可以利用墙体的蓄热能力获得节能效果，房间空气温度垂直分布状况主要取决于通风路线而非采暖方式，因而房间设有通风系统时，顶棚辐射采暖房间的舒适性要优于另外两种采暖方式。

Analysis of Indoor Thermal Environment Testing with High Air Exchange in Winter Season

Indoor thermal environment of a heating room with high air exchange is tested and discussed in winter season, and three different heating methods, i.e. heating ceiling, conventional radiator heating and warm-air heating, are used in the simulating experiments, respectively. The result shows that the former could save energy by thermal storage ability of the wall, the vertical indoor air temperature distribution is not mainly determined by heating method, but the way of air current. When radiant heatmg ceiling is used, indoor thermal comfort is better than the other two under the condition of high air exchange.
