Experimental Study of Solar Hot Water System Design

Abstract

This paper investigates the design of flat-plate solar collector system experimentally.The production amount of hot water depends on the type and size of the system, the amount of sun rays available at the site, proper installation, and the tilt angle and orientation of the collectors with respect to the south direction. The results show that the amount of the energy collected by the thermal fluid and the absorber plate are inversely proportional to that thickness and diameter of both riser and drum tubes, and it decreases when the air gab between glasses layer increases( prevents the sun rays and the solar effect ).The intensity of the mean sun rays daily per hour is an important factor to the energy absorbed by the collector. This study used aluminumas an absorber plate because its thermal conductivity is high more than copper and mild steel ,its price is cheap.
