Energy and exergy analyses of a new solar-assisted cogeneration cycle for simultaneous heating and triple effect cooling applications

This paper presents the energy and exergy analyses of a new cogeneration cycle for simultaneous production of heating and cooling. The effect of some influenced operating variables is observed on energy output, exergy output, energy and exergy efficiency of proposed cycle. Second law analysis indicates that around 3% of solar heat exergy is available as heating and cooling output and remaining is destroyed due to irreversibility in the various components of the cycle as well as lost via exhaust. It is found that maximum exergy destruction occurs in central receiver (52.5%) and heliostat field (25%) followed by condenser of ejector refrigeration cycle (ERC) (3.98%), heat recovery vapour generator (HRVG) (3.79%) and ejector (3.72%).
