Energy, exergy and environmental impact analysis of concentrated PV/cooling system in Turkey

摘要

In this study, a Concentrated Photovoltaic Cooling System has been designed and a prototype has been produced. This system is intended to meet the need for cooling and electricity of the building where this system is applied in hot summer days. The produced prototype has been tested with/without using a concentrator. The obtained data was used to analyze the energy, exergy and environmental cost. During performance of experiments, using a concentrator did not affect the thermal energy gain and total thermal energy gain was calculated as approximately 30 W in the system. Besides, use of a concentrator increased the exergy efficiency. Using the concentrator increased the back side temperature of panels, thus electrical performance is lower than the systems without concentrator. The system allows to economize around 0.1 phi per hour due to reduced generation of CO2.
