基于人体最不舒适部位的供暖温度研究

Heating temperature based on the most uncomfortable part of human body

根据气候室实验数据,研究了我国北方地区常用的地板辐射供暖和散热器供暖环境下的室温分布特征,以及其对人体不同部位局部热感觉与热舒适的影响规律,并对最不舒适部位处的空气温度与供暖室温的关系进行了探讨。结果表明:室温为19℃时,2种供暖环境中人体全身热感觉平均值分别为-0.11和0.08;脚踝部位的热感觉投票都是最低的,分别为-0.17和0.04;当满足脚踝部位热感觉为中性时,即可满足全身热舒适。智慧供热温度控制策略为:应满足脚踝部位的热舒适,地板辐射供暖室温控制点(室中心1.1 m高度处)温度为18.7℃,散热器供暖为20℃。

According to the experimental data in a microclimate chamber,studies the distribution characteristics of room temperature in the radiant floor heating and radiator heating environments commonly used in northern China,and its influence on the local thermal sensation and thermal comfort of different parts of the human body,and discusses the relationship between the air temperature at the most uncomfortable part and the heating temperature.The results show that when the room temperature is 19℃,the average overall thermal sensation vote in the two heating environments is-0.11 and 0.08,respectively.The thermal sensation votes of the ankle are all the lowest,which is-0.17 and 0.04,respectively.When the thermal sensation of the ankle is neutral,the overall thermal comfort would be satisfied.The intelligent heating temperature control strategy is as follows:under the premise of ankle thermal comfort,the temperature at room temperature control point(at a height of 1.1 m in the center of room)is 18.7℃for the floor radiant heating,and 20℃for the radiator heating.
