严寒地区城市冬季室外热舒适研究

Study on Outdoor Thermal Comfort in Winter in Severe Cold Regions

为了研究严寒地区城市居民在冬季室外环境下的热舒适,在严寒地区典型城市哈尔滨采用现场环境实测和问卷调查相结合的方式,分析了冬季室外环境下人们对环境温度、湿度、风速、辐射的满意度以及总体舒适度和满意度;最后,通过回归分析得出了适用于严寒地区冬季室外环境的热感觉预测模型和综合舒适度评价模型,并对该地区城市冬季室外环境舒适性的提高提出了一些改善措施。

The paper provides analysis on how satisfied people feel to ambient temperature, humidity, wind velocity and solar radiation and their overall comfort and satisfaction through on-the - spot environmental measurements and questionnaires in Harbin （a typical severe cold city） , so as to study outdoor thermal comfort of urban residents in winter in severe cold regions. Finally, regression analysis was used to establish the thermal sensation and comfort evaluation model and some measures were put forward to improve the outdoor thermal comfort of the city in winter in severe cold regions on the basis of the model.
