In this study, the overall performance of air PV/T, based on energy and exergy analysis has been investigated. Two combinations of air PV/T, which consist of unglazed and glazed air PV/T, are considered. Thermal analysis and numerical calculations were carried out, and the performance parameters of the system for the climate conditions of Kerman were studied. The results are presented in graphs...

Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...
