一种被农业工程师正式命名为通风式太阳能贮温墙最近在加拿大安大略省利奇顿农业技术学院研究成功。在有阳光的冬季,这种太阳能收集器能提供维持畜舍最适温度的全部热能。而且还可贮存大量热能在夜间施放出来。这种墙可以附加到畜舍、农村商店乃至新建筑的墙上,而且不需要特殊的建筑材料。作为附加墙,最好是面向正南贴到原墙外。但也允许正负20～30度角的偏向而不致于损失很多太阳能。通过在学院试验猪厩安装测试,效果良好:太阳能收集器高8呎,复盖于猪厩建筑物南墙。在冬季提供了26×60平方呎舍内所需热量的50％。加热贮温墙的关键部件是双孔空心泡沫混凝土砖。砖厚10吋,比一般的水泥砖多25％的中空空间以及多75％的贮热能力。在晴朗的冬季白天,能使室内温度达到13℃。
A type that was formally named by the agricultural engineer as a ventilated solar storage wall was recently successfully researched at the College of Agriculture and Technology in Ontario, Canada. In the sunny winter, this solar collector can provide all the thermal energy needed to maintain the optimum temperature of the house. And also can store a lot of heat released at night. This wall can be attached to the walls of livestock houses, rural shops and even new buildings, and does not require special building materials. As an additional wall, it is best to face the south just past the original wall. However, the positive and negative angles of 20 to 30 degrees are also allowed without losing a lot of solar energy. Through the installation of the test swine in the college, the effect was good: the solar collector was 8 inches high and covered the south wall of the pig building. In winter, 50% of the heat required in a 26 x 60 square foot house is provided. The key part of the heating storage wall is a double-hollow hollow foam concrete brick. The bricks are 10 inches thick, 25% more hollow space than ordinary cement bricks, and 75% more heat storage capacity. In the sunny winter day, the room temperature can reach 13°C.
