摘要
加强建筑外围护结构的节能措施是减少建筑能耗最直接有效的手段。作为现代装配式建筑,井干式木结构建筑的节能关键在于其外墙的保温隔热性。对井干式外墙墙体构件进行设计,并采用防护热箱法测试其热工性能。经测试,井干式墙体试件的传热系数为0.809 W/(m^(2)·K),复合墙体的导热系数为0.11 W/(m^(2)·K)。将理论值与实测值进行对比,相对误差在4%。结果表明:井干式墙体符合《公共建筑节能设计标准》相关要求,可在南方地区外墙建造直接应用,在绝大多数夏热冬冷地区、夏热冬暖地区及温和地区也可直接作为围护结构外墙使用。
Strengthening energy-saving measures for building envelope structures is the most direct and effective way to reduce building energy consumption.As a modern prefabricated building,the key to energy conservation in the well dry wooden structure building lies in the thermal insulation of the exterior walls.This study designed the components of the well dry exterior wall and tested their thermal performance using the protective hot box method.After testing,the heat transfer coefficient of the well dry wall specimen was 0.809 W/(m^(2)·K),and the thermal conductivity coefficient of the composite wall was 0.11 W/(m^(2)·K).By comparing the theoretical value with the measured value,their relative error was within 4%.The results showed that the well dry wall could meet the relevant requirements of the"Energy Saving Design Standards for Public Buildings"and can be directly applied in the construction of exterior walls in southern regions.It can also be directly used as an enclosure structure exterior wall in the vast majority of areas with hot and cold summers,hot and warm summers,and mild regions.
