蒙中地区农牧民住宅冬季热舒适调查

Investigation on the Thermal Comfort of Farmers and Herdsmen’s Housing in Central Inner Mongolia

严寒C区冬季农牧区居民住宅受当地经济条件影响,多采用传统供暖模式,其地理位置特殊,昼夜温差较大,气候参数较复杂。本文选取严寒C类蒙中地区某农牧区不同住宅进行跟踪测试,研究建筑室内外热环境对人体热舒适的影响。采用客观环境参数测试和主观问卷调查的方法,进行理论分析确定农牧区居民热中性温度。研究发现三种住宅中实测平均热感觉指数MTS整体均高于预测平均热感觉指数PMV,说明当地农牧民能够适应温度偏冷环境。土坯住宅、砖瓦住宅、惠民工程住宅的预测热中性温度和实测差值分别为1.6,1.4和1℃,惠民工程住宅差值最小,室内热舒适度最高。

Residential houses in agricultural and pastoral areas in severe cold C area in winter are affected by local economic conditions, and most of them use traditional heating mode. The geographical location is special, the temperature difference between day and night is large, and the climatic parameters are more complicated. Tracking tests was conducted to study the impact of indoor and outdoor thermal environments of buildings on human thermal comfort.Objective environmental parameter tests and subjective questionnaires were used to conduct theoretical analysis to determine the heat-neutral temperature of residents in agricultural and pastoral areas. The study found that the measured average heat sensitivity index MTS in the three types of houses was higher than the predicted average heat feeling index PMV, indicating that local farmers and herders were able to adapt to the cold temperature environment. The predicted heat neutral temperature and measured difference of adobe house, brick house and Huimin engineering house are 1.6, 1.4and 1 ℃,the difference between Huimin engineering housing is the smallest and the indoor thermal comfort is the highest.
