内蒙古河套地区农牧民住宅冬季热舒适现场研究

Field study of farmer’s houses comfort in winter for Hetao Region,Inner Mongolia

对内蒙古河套地区农牧民住宅冬季室内微气候参数进行连续七天现场测试,同时采用横向加纵向的调研方法对农牧民的热感觉、热舒适等主观反应进行问卷调查。对所得实测数据和调查问卷运用Probit回归分析结果显示:内蒙古河套地区农牧民住宅冬季实测热中性温度为17.8℃,预测热中性温度为20.2℃,两者相差2.4℃;热感觉实测模型为MTS=0.191top-3.405,热感觉预测模型为PMV=0.224top-4.551;80%可接受温度范围为15.7℃-25.5℃;热期望温度为20.7℃。研究表明:内蒙古河套地区冬季农牧民热中性温度较高且农牧民热期望偏向于较热中性更暖一些的热环境。

Indoor microclimate parameters of farmers and herdsmen residence in Hetao region of Inner Mongolia were tested on site for seven days in winter.At the same time,the subjective responses of residents such as thermal sensation and thermal comfort were investigated by means of horizontal and vertical investigation.The results of Probit regression analysis of the measured data and survey results showed that the thermal neutral temperature is 17.8℃in Hetao region of Inner Mongolia,and predicted thermal neutral temperature is 20.2℃with a difference of 2.4℃.The actual model of thermal sensation is MTS=0.191 top-3.405 and the prediction model of thermal sensation is PMV=0.224 top-4.551.The acceptable temperature range for 80%of residents is 15.7℃to 25.5℃.The expected thermal temperature is 20.7℃.The results show that the thermally neutral temperature of herdsmen’s houses in Hetao region of Inner Mongolia is higher in winter,and the expected thermal temperature of herdsmen’s houses tends to be warmer than thermally neutral temperature.
