夏热冬冷地区过渡季热适应模型研究
Thermal adaptation model of transition seasons in hot summer and cold winter zone
摘要：
基于全国热舒适调研数据库，对夏热冬冷地区自然通风环境中人体热舒适进行了研究，分析了代表性城市上海和武汉的热环境参数和人体主观热反应，建立了2个城市的热感觉评价模型和热适应模型，得到了热中性温度和人体可接受温度区间。结果表明，上海市和武汉市在自然通风环境下的人体可接受温度上限较高，80%的人可接受温度上限均为30.7 ℃。建立了夏热冬冷地区过渡季自然通风环境热适应模型。通过多元线性回归分析，发现室内空气温度和服装热阻对上海市人员热感觉具有显著性影响，室内空气温度、相对湿度和人员服装热阻对武汉市人员热感觉具有显著性影响，其中室内空气温度为影响最显著因素。
Abstract：
Based on the national thermal comfort survey database, the thermal comfort of human body in natural ventilation environment in hot summer and cold winter zone is studied, the thermal environment parameters and subjective thermal response of human body in representative cities Shanghai and Wuhan are analysed, the thermal sensation evaluation models and thermal adaptation models of the two cities are established, and the thermal neutral temperature and the acceptable temperature range of human body are obtained. The results show that the upper limit of acceptable temperature of human body in natural ventilation environment is higher in Shanghai and Wuhan, and the upper limit of acceptable temperature for 80% of the people is 30.7 ℃. A thermal adaptation model of natural ventilation environment in hot summer and cold winter zone in transition season is obtained. Through multivariate linear regression analysis, it is found that the indoor air temperature and clothing thermal resistance are the significant factors influencing the human thermal sensation in Shanghai, while the indoor air temperature, relative humidity and clothing thermal resistance are the significant factors in Wuhan, and indoor air temperature is the most significant factor in two cities.
