| dc.description.abstract | This study investigates the thermal performance of a heat pipe heat recovery system in air-to-airheat recovery systems using a nanofluid of Al2O3(aluminum oxide) particles and distilledwater. The experimental setup used 15 wickless vacuumed copper pipes with a length of1000 mm, a 10.5 mm inner diameter and a 12 mm outer diameter. The evaporator sectionconsists of 450 mm of heat pipes, the condenser section is 400 mm, and the adiabatic section is150 mm. In experimental studies, 33% of the evaporator volume of the heat pipes was filledwith working fluids. Experiments were carried out at temperatures between 25ºC and 90ºC byusing five different cooling air flows (40 g/s, 42 g/s, 45 g/s, 61 g/s and 84 g/s), and two differentheating powers (3 kW and 6 kW) for the evaporation section, to determine the heat removedfrom the condensation section. Experiments were performed for distilled water and Al2O3nanofluid, respectively, and the results were compared with each other. As a result of theexperiments, it was observed that using a nanofluid as the working fluid increased the efficiencyof the heat pipe. The highest efficiency (? = 59%) was obtained in the experiments carried outusing an Al2O3 nanofluid at a heating power of 3 kW and an air flow of 112 g/s. | en_US |
