摘要
Abstract
With the acceleration of urbanization and the increase in floor height,wall-mounted solar water heaters have attracted attention due to their high space utilization and good integration with building appearance.As an important component of wall-mounted solar water heaters,the thermal performance of solar collectors will directly affect the thermal performance of wall-mounted solar water heaters.Based on this,this paper conducted experimental analysis on the thermal performance of wall-mounted solar water heaters using flat plate solar collectors and U-shaped tube solar collectors(hereinafter referred to as"flat plate collectors"and"U-tube collectors"respectively)at different installation angles.The results show that:1)The daily useful heat gain of flat plate collectors decreases with the increase in installation tilt angle,with a 15%reduction at a 90° tilt compared to 70°.The daily useful heat gain of U-tube collectors remains relatively stable across different tilt angles,with only a 2%increase at 70° compared to 90°.2)Under the same conditions,U-tube collectors consistently achieve higher daily useful heat gain than flat plate collectors,with increases of 12%,20%,and 23%at tilt angles of 70°,80°,and 90°,respectively.3)The heat loss factor of U-tube collectors is approximately 6%lower than that of flat plate collectors under the same conditions.关键词
