摘要
目前,我国传统砖木民居普遍存在建筑围护结构构造单一、能耗较高、保温隔热性较差等问题。为了进一步研究寒冷地区传统砖木民居冬季室内环境特征,本文以滑县道口镇顺河北街某宅为研究对象,首先开展了围护结构构造层次的实地勘察,其次对其室内外温度、相对湿度、风速风温、二氧化碳浓度等各项环境参数进行为期约5个月的实时监测,并对建筑实测结果及室内外各项环境参数进行关联分析。分析结果表明:传统砖木民居围护结构的“青砖墙、薄屋面、薄地面、单层门窗”的构造体系,是导致其建筑保温性能较差、室内外昼夜温差大、采暖负荷较大的主要原因之一;测试期间室内外瞬时温差<5℃,室内风速<0.05 m/s,室内平均二氧化碳浓度<500 ppm,且室内外湿度差<10%,较客观地反映了传统砖木民居围护结构保温性、气密性较差的问题。
At present,the traditional brick and wood dwellings in China face problems such as single building envelope structure,high energy consumption,and poor thermal insulation.In order to further study the indoor environmental characteristics of traditional brick and wood dwellings in cold regions in winter,this paper,taking a house in Shunhe North Street,Daokou Town,Huaxian County as the research object,conducted a field survey of the envelope structure level.Then,it monitored the indoor and outdoor temperature,relative humidity,wind speed and temperature,carbon dioxide concentration and other indoor environmental parameters for about five months.And the correlation between the measured results and the indoor and outdoor environmental parameters was analyzed.The results show that the structural system of"green brick wall,thin roof,thin floor,single-layer doors and windows"of the envelope structure of traditional brick and wood dwellings is one of the main reasons for its poor thermal insulation performance,large temperature difference between indoor and outdoor during day and night,and large heating load.During the test period,the indoor and outdoor instantaneous temperature difference is less than 5℃,the indoor wind speed is less than 0.05 m/s,the indoor average carbon dioxide concentration is less than 500 ppm,and the indoor and outdoor humidity difference is less than 10%,which objectively reflects the poor thermal insulation and air tightness of the envelope structure of traditional brick and wood dwellings.
