Designing and Constructing a demostic compound solar heater

Abstract

In this research the design and construction of a solar heater system as a solar complex with a total area of the solar centre 1.54m2 and use the Aluminum foil as a surface reflector to radiation because of a characterized by the reflectivity of (98%) and efficiency in this centre (72%) . The experiments was done in the province of Anbar during ( Janwary – February – March ) 2011 boil water with temperature degree (100 Co) was obtained during one hour only and for almost 19 liters. The efficiency of the solar heater is changed with the change of hours in which they are measured and this change is due to the difference in the amount of solar radiation falling on the center.
