【摘要】：论文通过各类的文献检索，针对我国寒区农村居住建筑冬季室内热环境的相关研究进行了较详细的综述。包括采暖能耗现状、冬季室内热环境现场测试、采暖方式和围护结构方面的现状及有关我国寒区农村居住建筑冬季室内热环境计算参数研究现状。总结出：1.我国北方地区农村居住建筑冬季采暖能源结构基本向商品能源转变，生物质能源所占比例较小。2.从现场室内热环境测试的数据来看，我国寒区农村居住建筑冬季室内热环境质量普遍较差。分析其可能原因：1.冬季采暖方式单一，火炕和土暖气是主要的采暖方式；2.围护结构热工性能差，外墙材料主要为490或370清水砖墙，大多无保温层；外窗多为单层木窗框，密封性较差等等。论文采用了现场调研的研究方法分析了严寒地区农村居住建筑冬季室内温度计算参数与人体热舒适的关系，调研内容包括室内外物理环境参数的现场测试和主观问卷调查。采用操作温度(operative temperature)to作为严寒地区冬季农村室内热舒适评价指标。最终总结了严寒地区农村居住建筑概况、人员背景、主要采暖方式以及室内热环境状况、主观感觉投票值、热中性温度、舒适温度区间及热期望值及分析其他因素对人体热舒适的影响。论文选择了在严寒地区农村调研中的某一栋农村居住建筑，在采暖期间的一段时间（2013年1月24日到2013年4月9日）进行室内温湿度的逐时测试。分析不同房间的室内热环境差异、采暖房间室内空气温度场分布、能耗情况及人体主观热舒适情况。最后论文运用TRNSYS能耗模拟软件进行模拟和对比分析，将典型农村居住建筑作为基准建筑，参照《农村居住建筑节能设计标准》GB/T50824-2013中规定的围护结构热工性能参数限制对典型居住建筑进行模拟优化改造，，以节能50%为目标，得出从节能角度考虑的舒适温度区间。
[Abstract]:In this paper, the relative research on indoor thermal environment in winter of rural residential buildings in cold regions of China is reviewed in detail through various literature searches. It includes the present situation of heating energy consumption, the field test of indoor thermal environment in winter, the present situation of heating mode and enclosure structure, and the research status of indoor thermal environment calculation parameters in winter of rural residential buildings in cold regions of China. Sum up one of them. In northern China, the heating energy structure of rural residential buildings in winter is basically transformed to commercial energy, and the proportion of biomass energy is small. According to the data of indoor thermal environment test, the indoor thermal environment quality of rural residential buildings in cold region is generally poor in winter. Analyze the possible cause: 1. The heating mode in winter is single, the main heating way is Kang and earth heating. The thermal performance of the envelope structure is poor, the exterior wall material is mainly 490 or 370 clear water brick wall, most of the exterior windows are single layer wooden window frame, the sealing property is poor and so on. This paper analyzes the relationship between indoor temperature calculation parameters and thermal comfort of human body in winter of rural residential buildings in severe cold area by using the method of field investigation. The research content includes field test and subjective questionnaire of physical environment parameters in and out of house. The operative temperature)to is used as the evaluation index of indoor thermal comfort in the cold winter rural areas. Finally, the general situation of rural residential buildings, the background of personnel, the main heating methods, the indoor thermal environment, the subjective feeling voting value, the thermal neutral temperature, are summarized. Comfort temperature range and thermal expectation and analysis of other factors on human thermal comfort. In this paper, one of the rural residential buildings in the cold area is selected, and the indoor temperature and humidity are tested in a period of time (January 24, 2013 to April 9, 2013) during the heating period. The difference of indoor thermal environment in different rooms, the distribution of indoor air temperature field, energy consumption and subjective thermal comfort of human body were analyzed. Finally, the paper uses the TRNSYS energy consumption simulation software to simulate and compare the typical rural residential buildings as the benchmark building. According to the limitation of thermal performance parameters of envelop structure stipulated in GB/T50824-2013, the typical residential buildings were simulated and optimized, and the comfort temperature range was obtained from the point of view of saving energy by 50% energy saving.
