The multi-inlet air-cooled photovoltaic/thermal (PV/T) technology not only avoids the poor heat transfer conditions of single-inlet PV/T air collectors but also reduces photovoltaic (PV) peak temperature and improves solar energy utilization. Since use no more than three inlets, increase in thermal efficiency is significantly effective. Therefore, a numerical analysis an collector with two side...

Hybrid Photovoltaic Thermal (PVT) collectors are an emerging technology that combines PV and solar thermal systems in a single solar collector producing heat and electricity simultaneously. The focus of this thesis work is to evaluate the performance of unglazed open loop PVT air system integrated on a garage roof in Borlänge. As it is thought to have a significant potential for preheating vent...

The unpredictability of heat demand–supply is one the major challenges in our future sustainable energy system. Thus, coming up with new methods storage for operating solar systems during low irradiance among advanced technical approaches this field. compact integrated thermal collector-storage have recently attracted researchers’ attention due to direct usage stored as well reduced space occup...

Cogenra company has created a low concentration PV/Thermal system that produces both thermal energy and electricity simultaneously, mainly for commercial and industrial applications. The realization of a system that combines photovoltaic modules, solar thermal collectors and concentrating mirrors makes it a complicated system to study. So far, only simple studies have been made on Cogenra’s LCP...

This work aims to design and dynamically simulate a polygeneration system that integrates solar-assisted desiccant cooling for residential applications as an alternative vapor compression systems. The overall plant layout supplies electricity, space heating cooling, domestic hot water, freshwater single-family townhouse located in the city of Almería Spain. leading technologies used are photovo...

Abstract In the current energy context, solar is cheapest source of renewable energy. Photovoltaic cells (PV) and air thermal collectors (ATC) are used to convert irradiation into electricity heat. this research a model for hybrid system consisting in photovoltaic panel behind which hot collector was designed tested. This produces both heat, from sun, based on principle two one. Romanian climat...
