真空管太阳能热水器管横置与斜置的比较(1)——单管横置与斜置时入射乘积因子的比较

Compare of Evacuated Tubular Solar Water Heaters on the Horizontal Aside Tubes and Tilted Aside Tubes(Ⅰ)——Compare About the Product Factor of Incidence on the Single Horizontal Aside Tube and Single Tilted Aside Tube

提出了射乘积因子的概念,计算并比较了真空集热管单管横置与斜置时的入射乘积因子,得出了仅就单管入射乘积因子而言,斜置优于横置的结论.

An idea about product factor of incidence is raised, the product factor of incidence is calculated and compared on the single horizontal aside solar evacuated collector tube and single tilted aside solar evacuated collector tube, a conclusion is obtained which tilted aside is better than horizontal aside, but it is limited to single tube.
