传统毡房围护结构热工性能改良研究
|
摘要
为改善传统毡房围护结构的热工性能,通过防护热板法确定出适宜的柔性保温材料,分别与传统毡房苫毡体系结合,组成不同的新型苫毡体系。采用防护热箱法测试其传热系数,结果表明:采用羊毛毡改良的苫毡体系热工性能最好,但其自重过大,不便于毡房搭建且不利于传统毡房的整体稳定性;采用自粘橡塑保温棉改良的苫毡体系热工性能较好,且质轻价低性能稳定,可用于传统毡房苫毡体系的改良。利用ANSYS FLUENT16.0对苫毡体系改良前后的传统毡房进行室内热环境模拟,分析得出苫毡体系经自粘橡塑保温棉改良后的毡房室内热环境有了较大改善,能够满足《绿色农房建设导则(试行)》的最低要求。
In order to improve the thermal performance of the traditional yurt building enclosure, suitable flexible insulation materials are determined by the guarded hot plate. The identified materials are combined with the traditional felt system to form different new felt systems.The heat transfer coefficient was tested by the guarding heat-box method. The results show that the felt system modified by wool felt has the best thermal performance, but its self-weight is excessive, which is not convenient for the yurt to be built and is adverse to the whole stability of the traditional yurt; The felt system modified by self-adhesive rubber-plastic insulation cotton has better thermal performance, light weight and low performance, which can be used for the improvement of the traditional felt system. The ANSYS FLUENT16.0 was used to simulate the indoor thermal environment of the traditional yurt before and after the improvement of the felt system. It was found that the indoor thermal environment of the yurt improved by self-adhesive rubber-plastic insulation cotton has been greatly improved. It has been able to meet the minimum requirements of the "Green Farm Building Construction Guidelines(Tria)".
