A mathematical model of thermal performance of a solar air heater with slats
Ammari, H.D. - In: Renewable Energy 28 (2003) 10, pp. 1597-1615
A mathematical model for computing the thermal performance of a single pass flat-plate solar air collector is presented. Air channels were formed by providing metal slats running along the circulated air passage linking the absorber plate by the bottom one in an endeavor to enhance the thermal...

Agricultural solar air collector made from low-cost plastic packing film
Ahmad, N.T. - In: Renewable Energy 23 (2001) 3, pp. 663-671
Special attention has been paid to build a simple solar air heater from cheap plastic wrapping film with air bubbles, for use in drying operations on a farm (grain, fruit, fish, etc.). The model used was a single-sheet cylindrical collector and, after it had gained some heat, another layer of...

Experimental operating cell temperature assessment of BIPV with different installation configurations on roofs under Mediterranean climate
D'Orazio, M.; Di Perna, C.; Di Giuseppe, E. - In: Renewable Energy 68 (2014) C, pp. 378-396
The presence of an air gap between a photovoltaic (PV) module and roof facilitates ventilation cooling under the device and consequently reduces cell temperature and improves its performance. In case of rack-mounted PV installation, the Nominal Operating Cell Temperature (NOCT) method could be...
