Three Integrated Collector Storage Solar Water Heaters (ICSSWH) have been designed, constructed and experimentally studied in comparison to a Flat Plate Thermosiphonic Unit (FPTU). Each of the ICS experimental models consists of one cylindrical tank horizontally mounted in a stationary...

In reflective concentrating systems, mirrors play an essential role in directing and concentrating the energy from the sun to the modules. Shortcomings like misalignment, shading or bending of mirrors, due to their weight or wind, imply a higher probability of attenuated energy and non-uniform...

A study, in which a suitable artificial neural network (ANN) and TRNSYS are combined in order to predict the performance of an Integrated Collector Storage (ICS) prototype, is presented. Experimental data that have been collected from outdoor tests of an ICS solar water heater with cylindrical...

An Integrated Collector Storage (ICS) solar water heater was designed, constructed and studied with an emphasis on its optical and thermal performance. The ICS system consists of one cylindrical horizontal tank properly mounted in a stationary symmetrical Compound Parabolic Concentrating (CPC)...

Integrated collector storage (ICS) systems are compact solar water heaters, simple in construction, installation and operation. They are cheaper than flat plate thermosiphonic units, but their higher thermal losses make them suitable mainly for application in locations with favourable weather...

New types of ICS solar systems were designed and outdoor tests of experimental models were performed. The systems consist of single cylindrical horizontal water storage tanks placed inside stationary truncated asymmetric CPC reflector troughs of different design. We used high emittance absorber...

Cylindrical type storage tanks are used in most commercial ICS systems, as they resist to the pressure of water mains. ICS systems with one or two cylindrical storage tanks combined with curved reflectors are cost effective devices and can be easily used in domestic solar applications. In this...

The use of a horizontal cylindrical water storage tank contributes to pressure resistant, low height and efficient ICS solar systems. These systems can satisfactorily achieve water heating when the cylindrical storage tank is combined with stationary CPC or involute type curved reflectors. The...

Low cost CPC solar collectors were designed, constructed and tested. The collectors consist of two separate absorbers, which are horizontally incorporated in a stationary asymmetric CPC mirror. The efficient operation of the proposed collectors is due to the direct absorption of a large part of...

Two types of ICS solar water heaters designed, constructed and tested. The systems consist of two cylindrical storage tanks, which are connected in series and are horizontally incorporated in a stationary asymmetric CPC type mirror. The efficient operation of the system is due to the thermal...
