摘　　要：为考察冬季非空调环境下人体热感觉,对厦门某高校教室的热舒适度进行了现场测试。在测量室内外热舒适参数的同时,通过问卷调查得到了人体热反应样本。分析样本得出厦门高校教室冬季非空调工况下人体热中性温度和热期望温度分别为19.3和19.4℃。综合考虑温度、相对湿度、平均辐射温度、风速及服装热阻对坐姿轻度活动状态人体的热舒适影响,使用MATLAB软件进行非线性回归,得到非空调工况下热舒适预测方程。该预测方程与实测得到的人体热舒适投票两者结果有较高相关度,同时较大程度上反映了冬季非空调环境下人体热感觉的变异。To examine human＇s thermal sensation in the non-air-conditioned environment in winter,performs field test in a university classroom in Xiamen.Measures indoor and outdoor thermal comfort parameters and obtains the thermal response samples from the objects by means of questionnaires.Analyses the samples,and concludes that the thermal neutral temperature and the thermal preferred temperature is 19.3 ℃ and 19.4 ℃ respectively.Considering the impact of temperature,relative humidity,mean radiant temperature,velocity and clothing thermal resistance on thermal comfort of sedentary slight activity,establishes a thermal comfort prediction equation under the non-air-conditioned condition by nonlinear regression using the MATLAB software.The results from the equation have higher correlation with that of thermal comfort votes and it reflects the variation of human thermal sensation in non-air-conditioned environment in winter to a larger extent.
