Performance analysis of applying a PVT collector to producefresh water and cooling

Today, due to the energy crisis and the limitation of fossil fuels,renewable resources are more important. In this study, the aim is tosimultaneously production of electricity, fresh water and cooling effect.The proposed system in this regard is the PVT system as the energysource to produce heat and electricity, the RO system that has the task ofproducing fresh water and double effect absorption refrigeration systemwhich produces cooling. Due to the fact that proposed PVT system doesnot have a fossil fuel source, it is free from air pollution. it is concludedthat by increasing the feed temperature, the feed pressure reduces andwith the increase in water temperature, the pump's work consumptiondecreases, which saves energy. The increasing temperature of the feedingwater of RO unit reduces the amount of the fresh water and recovery ratioof the desalination water. Finally, it was found that for the absorptionsystem, by increasing the temperature of the evaporator, the energy andexergy efficiency of the system and the performance coefficient of thesystem increase.
