A novel solar trigeneration system integrating PVT (photovoltaic/ thermal collectors) and SW (seawater) desalination: Dynamic simulation and economic assessment

摘要: Abstract The paper investigates the integration of renewable energy sources and water systems, presenting a novel solar system producing simultaneously: electrical energy, thermal cooling domestic water. Such is designed for small communities in European Mediterranean countries, rich poor fossil fuels resources. polygeneration under analysis includes PVT (photovoltaic/thermal collectors), MED (multi-effect distillation) SW (seawater) desalination, single-stage LiBr–H2O ACH (absorption chiller) additional components, such as storage tanks, AHs (auxiliary heaters) BOP (balance plant) devices. produces simultaneously energy. delivered to grid, whereas may be used space heating and/or HW (hot water) production. As an alternative, can drive ACH, CHW (chilled cooling. Finally, combination with produced by auxiliary biomass-fired heater, convert into potable dynamically simulated means zero-dimensional transient simulation model. A thermo-economic also presented, aiming at determining optimal values most important design variables.
