Abstract
In order to study the outdoor thermal comfort during the transition season in Hefei, a university in Hefei adopted a combination of field environmental measurements and questionnaires to study the changes in thermal sensation and thermal comfort of outdoor people before and after the transition season. The rankings of the effects of temperature, wind speed, humidity, and solar radiation on human thermal comfort were obtained through surveys, and the proportion of each parameter’s influence on human thermal comfort was analyzed. The relationship between thermal sensation and thermal comfort was analyzed, and the application was established through regression analysis Prediction model of thermal sensation in autumn and winter outdoor environment in Hefei area.
Highlights
With the continuous decline of environmental quality and the continuous improvement of people's living standards, people's requirements for outdoor thermal environment are getting higher and higher
Evaluated COMFA's outdoor thermal comfort model for subjects with moderate to strenuous exercise [2]; Qian W took PMV Based on the model, the outdoor thermal environment comfort evaluation model OTCD was derived [3]; Chen X et al Used a combination of field environmental measurement and questionnaire survey to analyze people's satisfaction with meteorological parameters and overall in winter outdoor environment in Harbin Comfort [4]
The current research on human thermal comfort in Hefei area mainly focuses on indoor environment [5]
Summary
With the continuous decline of environmental quality and the continuous improvement of people's living standards, people's requirements for outdoor thermal environment are getting higher and higher. There is relatively little research on outdoor thermal comfort, especially in the thermal environment with dynamic changes in the transition season. The current research on human thermal comfort in Hefei area mainly focuses on indoor environment [5]. There is less research on outdoor thermal comfort, especially human thermal comfort in the transition season, and it cannot provide corresponding guidance for the outdoor thermal environment design in Hefei. By studying the influencing factors of outdoor thermal comfort before and after the transition season in Hefei, and here Based on the establishment of a thermal sensation prediction model, some improvement measures are proposed to improve the comfort of Hefei area, which has important guiding significance for rationally improving the quality of life of residents in Hefei area through architectural planning
