Abstract
In this study, the effects of six different working fluids, hexane, petroleum ether, chloroform, acetone, methanol and ethanol on the energy and exergy performance are investigated in evacuated tube solar collectors with thermosyphon heat pipe under three different air velocities as 2, 3 and 4Â msâ1. The six evacuated tube solar collectors with thermosyphon heat pipe with the same dimensions and properties are designated for the air heating and tested under the outdoor climatic conditions of UÅak, Turkey. The lowest energy and exergy efficiencies occur in the THPETC-Hexane under 2, 3 and 4Â msâ1, the highest energy efficiency occurs in the THPETC-Acetone for air velocity of 2 and 3Â msâ1 and in the THPETC-Chloroform for air velocity of 4Â msâ1. The highest exergy efficiency occurs in the THPETC-Acetone for air velocity of 2Â msâ1 and in the THPETC-Chloroform for air velocity of 3 and 4Â msâ1.
