| 摘 要： | 考虑太阳辐射和气温波动对围护结构外表面的热作用,利用天津市典型年气象资料,采用反应系数法,对16种外保温建筑模网墙体按朝向分别进行逐时不稳定传热量计算.根据计算结果,比较不同情况下各墙体的逐时总传热量,并与稳定传热的结果进行对比,重新对16种外保温建筑模网墙体进行了保温隔热性能评价.

| Abstract: | Considering the heat effect of solar radiation and fluctuation of temperature on the outside surface of building envelope,adopting a reaction coefficient method,with the typical-year meteorological date of Tianjin,the unsteady thermal output in successive time of sixteen building mold nets with exterior insulation is calculated by different direction.The accumulative thermal output of these building envelopes in different situations is compared according to these calculations.And comparing unsteady thermal output with steady thermal output,the performance of heat preservation and heat insulation of these building envelopes are evaluated anew. |
