Designing,manufacturing and performance experiments of corrugated-duct and air heating-purpose solar energy collectors

The solar-powered systems are mostly thought and used for the purpose of preparing sanitary hot water. the air heating collectors have recently started to come up with use areas. in this study,performances of the sanitary hot water preparation have been explored according to the experiment result data,on the subject of drying and domestic heating,with the purpose of increase efficiency,by designing and manufacturing solar radiation collectors in two different configurations as corrugated-duct and airflow-duct. one of the collectors has been taken into consideration as natural-flow and 1 meter; and since other one has been taken into consideration as forced-flow and circulation-duct,its airflow duct length has been 2 meters. as a result of the experiments; it has been obtained that the natural-flow and corrugated-duct collector's efficiency is 25%,and corrugated-duct and forced-flow collector's efficiency is 66%. © 2013 tibtd printed in turkey.
