Özet
Systems used in pre-heating the required clean air; waste heat recovery units used in industry and many waste heat plants. In this study, it is aimed to improve the thermal performance of the heat pipe heat recovery system by using pure water and nanofluids in air to air heat recovery systems. The fact that nanofluids, which have recently found a lot of application area, have been used in the experimental setup has added originality value to the study. As working fluid, MgO+CuO/Water hybrid nanofluid and MgOAl2O3/Water nanofluid were used in the heat pipe heat exchanger. With the use of these nanofluids, the improvement rates of thermal performance of the heat recovery system relative to pure water have been determined and attempted to comment. In the condenser region, which is the lower part of the heat pipes, when the cold air velocity was 0.751 m/s and Re=12300, it was measured that there was 77 % improvement for MgO+CuO/Water hybrid nanofluid and 91 % for MgOAl2O3/Water nanofluid.
