不对称辐射热环境中人体热反应实验研究

Experimental study on human thermal responses in an asymmetrical radiant thermal environment

在哈尔滨一微气候室中研究了外窗冷辐射与地板供暖造成的不对称、不均匀热环境中人体的生理和心理反应规律。16名受试者身着热阻为1.02clo的冬季服装参加了4种工况的实验。实验中测试了受试者的生理参数和微气候室的环境参数。结果表明:同一工况下局部皮肤温度、局部热感觉和热舒适都存在差异性;不同工况下局部皮肤温度、平均皮肤温度、局部和整体的热感觉和热舒适均具有显著性差异。外窗冷辐射对人体的皮肤温度、热感觉和热舒适有很大的影响。随着受试者与外窗距离的增大,其皮肤温度、热感觉和热舒适投票均会提高。小腿的热感觉和热舒适变化最显著。全身热感觉和平均皮肤温度、心率之间均存在线性相关性。

Studies the human physiological and psychological responses in the asymmetrical radiant thermal environment formed by cold exterior window and warm floor in a microclimatic chamber in Harbin. Sixteen subjects wearing winter clotties with 1. 02 clo clothing insulation take part in four experiments. Tests the physiological parameters of the subjects and the environmental parameters of the chamber. The results show that there are differences among local skin temperatures, local thermal sensation and thermal comfort in same conditions and significant differences among local and overall skin temperatures, local and overall thermal sensation and thermal comfort in different conditions. The cold radiation from the exterior window has a great influence on human skin temperature, thermal sensation and thermal comfort. The skin temperature, thermal sensation and thermal comfort increases with the increase of the subjects＇ distance from the exterior window. The local thermal sensation and thermal comfort for the calf are easily influenced by cold radiation. The overall thermal sensation has linear relationships with both mean skin temperature and heart rate.
