内蒙古中南部农牧区居民过渡季热舒适研究

Research on thermal comfort of residents in the transitional season in farming and pastoral areas of south central Inner Mongolia

以内蒙古中南部地区乌兰察布周边某农牧区为例,通过现场跟踪测试和主观调查相结合的方法,采用平均热感觉指数(predicted mean vote,PMV)和平均热感觉投票值(mean thermal sensation vote,MTS)以及热中性温度等指标,分析了生土民居、砖瓦民居、民生工程民居在过渡季的人体热舒适性。结果表明:在过渡季,三种民居中MTS与PMV存在偏差,但整体均为MTS高于PMV,说明居民能够适应温度较低环境;生土民居、砖瓦民居、民生工程民居的实测热中性温度分别为15.90、16.60和18.80℃,预测热中性温度和实测差值分别为2.10、1.90和1.20℃,民生工程民居差值最小,说明其室内热环境优于砖瓦民居和生土民居;对农牧区居民80%和90%实测热中性温度范围与室外日平均温度回归分析,得出适宜当地居民过渡季的人体热舒适模型,为研究农牧区居民在过渡季的热舒适性提供参考。

The article takes an agricultural and pastoral area around Ulan Qab in South central Inner Mongolia as an example.By combining on-site tracking test and subjective investigation,the thermal comfort of human body in the transitional season of raw soil dwellings,brick dwellings and civil engineering dwellings are analyzed using PMV,MTS and thermal neutral temperature and other indicators.The results show that in the transition season,there are deviations between MTS and PMV in the three types of residential buildings,but overall MTS is higher than PMV,and residents can adapt to a lower temperature environment.The measured thermal neutral temperature of the raw soil residential,brick and civil residential,and residential engineering residential are respectively 15.90,16.60 and 18.80℃.The difference between the predicted thermal neutral temperature and the measured are 2.10,1.90 and 1.20℃respectively.The difference of the civil engineering project is the smallest,indicating that the indoor thermal environment of this type is better than the brick residential and raw soil residential.Regression analysis of the measured thermal neutral temperature range and outdoor daily average temperature for 80%and 90%of residents in farming and pastoral areas is done,and a human thermal comfort model suitable for the transitional season of local residents is found,providing a reference for studying the thermal comfort of residents in the farming and pastoral areas of southern Inner Mongolia during the transition season.
