适宜重庆气候特点的现代木建筑围护结构热工性能研究

In this paper, parameters such as wall heat transfer, inner and outer surface temperature, and solar radiation intensity were measured, and the heat transfer coefficient of the timber frame outer wall was 0.53W/(m2 K), the heat transfer attenuation was 9.9, and the delay time was 5h, which is lower than the specified value of the wall heat transfer coefficient of the "Design Standards for 65% Energy Efficiency of Residential Buildings" in Chongqing area, but the thermal insulation performance of the external wall cannot meet the requirements of the "Code for Thermal Design of Civil Buildings".The research results of this article will provide a reference for further improving the thermal performance of the timber frame building envelope enclosure and improving the indoor thermal environment of the lightweight timber frame.
