摘要
以北京地区采用地板辐射供暖系统的建筑房间为研究对象,通过建立人体热平衡与房间热平衡方程,分析了地板表面温度、房间平均辐射温度、房间空气温度对人体热舒适性的影响。初步研究结果表明,当其他条件一定,人体处于静坐状态且为冬季室内习惯着装(服装热阻为1.2～1.5 clo)时,舒适的房间空气温度为17.4～20.9℃,对应的地板表面平均温度约为21.4～25.3℃;过高的地板表面温度不但不利于节能,同时也直接影响人体的热舒适感。
Taking a room with floor panel heating system in Beijing as an object, analyses the effects of the panel surface temperature, mean radiant temperature and indoor air temperature on human thermal comfort by establishing thermal balance equations of human body and heating room respectively. The results show that when other parameters remain constant, the comfortable indoor air temperature is 17.4℃ to 20.9℃ for a sedentary person with an indoor clothing habit of 1.2clo to 1.5clo in winter, corresponding to a panel surface mean temperature of 21.4℃ to 25.3℃, and that overhigh panel surface temperature both wastes energy and decreases human thermal comfort.
