Thermoeconomic analysis combines economic and thermodynamic analysis by applying the concept of cost, originally an economic property, to exergy. In this study, effects of different three working fluids as methanol, petroleum ether and distilled water on thermoeconomic analysis in the thermosyphon heat pipes which it heats the air is investigated. Under different air velocities, the energy and exergy efficiencies of the thermosyphon heat pipes are determined and compared in terms of thermoeconomic experimentally. Under all air velocities, while the highest energy and exergy performance are calculated for methanol, the lowest energy and exergy performance are calculated for petroleum ether. However, the thermoeconomic results of this study show that distilled water is more cost-effective than that of methanol and petroleum ether.
