基于气候的服装热阻对室内热舒适参数的影响

Influence of Clothing Insulation on Indoor Thermal Comfort Parameters in Different Climate

针对不同气候地区人们的着装特点,分析了在冬季供暖条件下,室外温度与室内服装热阻的关系,提出在热适应模型中,服装热阻是影响室内热舒适参数的重要因素,分析进入室内后服装对PMV的影响,以及改变服装热阻对建筑节能的意义。利用P.O.Fanger的热舒适方程,计算不同条件下服装热阻对PMV的影响,得到不同气候地区室内热中性时的设计温度、平均辐射温度、空气流速和湿度的取值范围,并提出考虑室外气候对服装热阻有影响时室内设计参数的修正方法。

For characteristic of people＇s dress in different climatic regions, the relationship between, the outdoor temperature and indoor clothing insulation is analyzed in heating conditions in winter, it is proposed that clothing insulation is an important factor affecting indoor thermal comfort parameters in thermal adaptation model. The influence between PMV and clothing insulation after entering room is expounded, as well as the significance of changing clothing insulation to save energy. The impact of clothing insulation on PMV is calculated under different conditions using P. O. Fanger＇s thermal comfort equation, and the range of indoor temperature, air velocity and humidity are decided in different climatic regions. It presents the correction method of indoor design paranwters, considering the impact of climate on outdoor clothing ins ulation.
