| 为了研究夏热冬冷地区秋冬季的室外热舒适情况,选取合肥地区进行研究,在合肥市某高校采取现场环境实测与问卷调查相结合的方式,研究了秋冬两季室外人群热感觉与热舒适的变化情况。通过调查得到了温度、风速、湿度与太阳辐射对人体热舒适影响程度的排序,以及各参数对人体热舒适影响的比重,分析了主观热舒适影响比重与期望,讨论了热感觉与热舒适的变化关系,探究了人体不同身体部位对热舒适性的影响,并引入PET和SET*预测热感觉的数学模型,通过回归分析建立了适用于合肥地区秋冬两季室外环境的热感觉预测模型。研究表明：合肥地区秋冬两季人们对室外环境热舒适性整体可接受度较高,而秋季高于冬季,其中面部对人们主观热舒适影响最大。影响室外热舒适的热环境参数主要为温度,环境相对湿度对其影响较小。在秋季,人们热舒适与热感觉变化呈二次函数变化关系,在冬季则呈现正相关变化；并且秋季变化远强于冬季。 |

| In order to study the outdoor thermal comfort in autumn and winter in Hefei, a college in Hefei adopted a combination of on-site environmental measurement and questionnaire surveys to study the changes in outdoor thermal sensation and thermal comfort in autumn and winter. Through the investigation, the ranking of the degree of influence of temperature, wind speed, humidity and solar radiation on human thermal comfort, as well as the proportion of each parameter’s influence on human thermal comfort, was analyzed, and the subjective thermal comfort influence proportion and expectations were analyzed. The relationship between thermal sensation and thermal comfort was analyzed,and explore the influence of different body parts of the human body on thermal comfort, and introduce the mathematical model of PET and SET* to predict thermal sensation, and establish a thermal sensation prediction model suitable for outdoor environment in autumn and winter in Hefei area through regression analysis. Studies have shown that people in Hefei have a higher overall acceptance of thermal comfort in the outdoor environment in autumn and winter, and autumn is higher than in winter, and the face has the greatest impact on people"s subjective thermal comfort. The thermal environment parameter that affects outdoor thermal comfort is mainly temperature, and the relative humidity of the environment has little effect on it. In autumn, people"s thermal comfort and thermal sensation changes have a quadratic function change relationship, and in winter there is a positive correlation change; and the change is much stronger in autumn than in winter. |
