陕西师范大学研制成一种浅池式太阳能集热器,它的外壳用塑料制作,池底长2米、宽1米,水平放置,池内充水,水内有一块金属吸热板,池内侧面及背面涂成白色,池顶覆盖双层玻璃,玻璃面与水平面之间的夹角与当地纬度相同,池底及四周用聚苯泡沫塑料保温。图为浅池式集热器的外貌。这种集热器采用定温放水方式,池内充人数公分深的自来水,经太阳闷晒,温度升高至所需温度时,出水口自动开启,便将热水放出。它节约钢材、安装维修 Shaanxi Normal University developed into a shallow pool solar collector, its shell made of plastic, the bottom 2 meters long, 1 meter wide, placed horizontally, the pool filled with water, the water has a metal heat-absorbing plate, the pool inside and The back is painted white, the top of the pool is covered with double glazing. The angle between the glass surface and the horizontal surface is the same as that of the local latitude. The bottom and the surrounding area are insulated with polystyrene foam. The picture shows the appearance of shallow pool collector. This collector uses constant temperature water release, the pool filled with a few centimeters deep tap water, the sun stuffy sun, the temperature rises to the required temperature, the outlet automatically open, it will release hot water. It saves steel, installation and maintenance
