摘要
对北纬40°南立面横置和竖置及倾角与纬度相同朝南放置南北轴向三种不同放置方式单位长度圆柱吸热体真空集热管的日能量收益及其年能量收益变化进行研究。结果表明,南立面上横置与竖置的圆柱吸热面真空集热管不论是日能量收益还是年能量收益都小于倾角为40°朝南放置南北轴向的情形,特别是夏季能量收益明显要低。夏季南立面单支横置管比竖置管的日能量收益明显要高。利用南立面太阳能资源的最佳安放方式为横置真空管。
According to the Clear - Day Model, daily energy gain and its annual variation of single evacuated collector tube with cylindric absorber in three different installation on building southern facade are studied. The solar energy gain of vertical installed tube and east - west horizontal installed tube comparing with local latitude tilted installed tube are presented. During the summer season the east - west horizontal installed tube has more solar energy gain than the vertical installed tube.
