摘要(Abstract)：

针对辐射供暖环境下,由于辐射不对称性给人体造成局部不舒适,本文利用PMV—PPD预测方法、人体主观投票和皮肤温度指标对人体热舒适进行了综合研究。试验结果表明:采用PMV—PPD方法预测得到的可接受热舒适区间与人体主观投票存在较大的差异。通过拟合方程预测分析:顶棚辐射供暖环境下,额头温度、手背温度、前臂温度和平均皮肤温度与热感觉相关性显著,当平均皮肤温度在33℃附近,额头温度在32.7℃附近,人体主观感觉舒适性良好;地板辐射供暖环境下,额头温度、手背温度、小腿温度和平均皮肤温度与热感觉密切相关,当人体平均皮肤温度在32.7℃附近,额头温度在32.3℃,人体主观感觉舒适性良好。
In view of the local discomfort to human body caused by radiant heating asymmetry in the radiant heating environment,the PMV-PPD prediction method,the subjective voting and the skin temperature indexes were used to conduct comprehensive researches on the thermal comfort of the human body. The test results show that the acceptable thermal comfort interval predicted by the PMV—PPD method is quite different from that obtained by the subjective voting. By prediction and analysis with the fitting equation:it is found that in the ceiling radiant heating environment, the temperature of the forehead,the back of hand and forearm and the average skin temperature are closely correlated with the thermal sensation. When the average skin temperature is about 33 ℃,the forehead temperature is about 32.7 ℃,the subjective feeling of human body is comfortable;In the floor radiant heating environment,the temperature of the forehead,the back of hand and forearm and the average skin temperature are closely correlated with the thermal sensation. When the average skin temperature is about 32.7 ℃,the forehead temperature is about 32.3℃,and the comfort subjectively felt by human body is good.
