Abstract

In this study, a type of Integrated Collector Storage (ICS) solar system is constructed and experimental tests are performed. The ICS system is a type of solar water heater with simple construction. In ICS, the storage tank is used for both water heating and storage, and there is no separate collector. Therefore, a larger storage tank is used which is subjected to direct solar radiation. In the present studies, the experimental model was investigated with three different reflectors. The results showed that the system has the lowest thermal efficiency with an aluminum foil reflector.
