严寒地区农村冬季室内热舒适温度研究

Study on indoor thermal comfort temperature of winter in severe cold rural area

国内外学者针对室内热舒适性进行了大量研究,但针对农村住宅的舒适性研究相对较少。本文根据严寒地区的气候特点、农村经济的发展水平、农村的建筑文化特点,考虑了火炕对农村热舒适的影响,建立了严寒地区农村住宅热舒适的物理数学模型,并通过MATLAB软件进行数值模拟,给出了在不同环境风速及相对湿度条件下的室内热舒适温度,分析了风速已定条件下的热舒适温度和PMV随相对湿度的变化情况,以及在相对湿度已定条件下的室内最佳风速和热舒适温度。本研究旨在为完善严寒地区的热工标准提供理论依据。

The domestic and foreign scholars have conducted a lot of researches on indoor thermal comfort,but there are few studies on the comfort of the rural housing. According to the climatic characteristics of cold regions,the development level of rural economy,rural architecture and cultural characteristics,considering the kang effect on rural thermal comfort,the physical mathematical model of rural residential thermal comfort in cold area was established. The numerical simulation was carried out by using MATLAB software. Giving the indoor thermal comfort temperature under different environment wind speed and relative humidity,the changes of thermal comfort temperature and PMV with relative humidity were analyzed,and the optimum wind speed and thermal comfort temperature under the condition of relative humidity are fixed. The research provides a theoretical basis for improving the thermal standards in severe cold areas.
