Influence of Installation Modes and Latitude on the Collector Performance

摘要

Using transient simulation software polysun to simulate flat plate collectors in different inclination and azimuth,analyzed outlet water temperature and solar radiation projected on collectors.Results show,in the summer,the collectors face east with 45 ° installation angle,can better absorb solar radiation,the outlet water temperature of collector is highest,while face south with 90 ° is the worst.In contrast to this,in winter,face east with 90 ° installation angle and face south with 90° installation angle are the best and worst for six different inclination and orientation.In Guangzhou,outlet temperature of collectors is steady and higher at 25 ° installation angle and face south,irradiation projected on collectors is irregular.
