本文讨论了美国内布拉斯加大学能源综合农场用于猪舍的一太阳墙的工作性能,文中给出了分析过程及18天墙的平均工作效率57.6％。多孔太阳墙主要由石子加一薄层水泥定位通过木型浇制而成。在风扇作用下,太阳加热过的环境空气可经过墙中的孔隙进入室内。与常规的固体块墙相比,多孔墙具有孔隙分布均匀,空气与石子间对流换热面积大等特点。该墙平均每天收集的热量约为117mJ。
This article discusses the performance of a solar wall used in pig farms at the University of Nebraska Energy Integrated Farm and gives an average of 57.6% of the analysis process and the average working efficiency of the 18-day wall. The porous solar wall is mainly made of stone and a thin layer of cement positioned by wooden pouring. Under the action of a fan, the sun-heated ambient air can enter the room through the pores in the wall. Compared with the conventional solid block wall, the porous wall has the characteristics of uniform pore distribution and large convective heat transfer area between the air and the stone. The average daily collection of the wall heat is about 117mJ.
