摘要
对兰州地区一所中学实验楼的特朗伯集热墙系统的热工与节能性能进行测试与调查分析评价。结果发现,在建筑建成10 a后的冬季正常运行期间,单组通风口的日对流供热量为6.89 kW,集热墙日平均热效率为18.4%,夜间稳定传热时段的传热系数为1.06 W/(m^2·K),综合热工节能性能良好。特朗伯集热墙式公共建筑在使用管理中应注意通风道内的清洁卫生、保持流道顺畅,定期维护检修以保证风口启闭装置功能良好,避免建筑后期改造装修中堵塞通风口、破坏集热墙的通风供热机理。
The thermal engineering and energy saving performance of the Trombe wall of a laboratory building in a middle school of Lanzhou region were measured and investigated.The results show that during the normal using period in winter 10 years after the building been built,the daily convection heat supply of single group vents is 6.89 kW,the daily average thermal efficiency of the Trombe wall is 18.4%,the heat transfer coefficient reach 1.06 W/(m^2·K)during the stable heat transfer period at night,and the comprehensive thermal energy saving performance is good.In addition,in the process of using the building,It is worth noting that the ventilated channel must be maintained clean and unhindered status for this kind of buildings,the vents devices must be repaired periodically in order to ensure good opening and closing function,and the heating mechanism of Trombe wall.
