A novel solar trigeneration system integrating Photovoltaic/Thermal collectors and seawater desalination: dynamic simulation and economic assessment
This paper investigates the integration of renewable energy sources and water systems, presenting a novel solar system producing simultaneously: electrical energy, thermal energy, cooling energy and domestic water. The polygeneration system under analysis includes photovoltaic/thermal solar collectors (PVT), a multi-effect distillation (MED) system for seawater desalination, a single-stage LiBr-H2O absorption chiller and additional components, such as storage tanks, auxiliary heaters and balance of plant devices. The PVT produces simultaneously electrical energy and thermal energy, at a maximum temperature of about 100 °C. The electrical energy is delivered to the grid, whereas the thermal …
Exergetic and exergoeconomic analysis of a renewable polygeneration system serving a small isolated community
A great interest has been arising in the last decade for the sustainable supply of energy and fresh water, also due to the rapidly growing demand from developing countries. Facing this demand by traditional technologies and fossil energy sources implies evident difficulties and risks, because of the scarcity and high cost of fuels and their relevant environmental impact in terms of local pollution and global warming emissions. Then, the efforts of researchers have been focusing on alternative solutions, either based on the use of renewable energy sources and on innovative plant schemes for the combined and efficient production of several energy and material flows. In this paper an innovativ…
