Abstract

In this experimental study, CuO/ZnO hybrid nanoparticles were synthesized by the co-precipitation method. While solid nanoparticles were synthesized, 5%, 10%, and 15% mass fractions of CuO were doped into ZnO nanoparticles. While preparing the nanofluids, sodium dodecyl benzene sulphonate (SDBS) surfactant material was used to prepare a homogeneous and hydrophobic suspension. The results of physical and chemical analyses of the synthesized nanoparticles were examined. In the experiments made with the heat pump, the coefficient of performance (COP) of the heat pump was calculated as 4.23 when deionized water was used as the working fluid. In the experiments with nanofluids using ZnO and 15% (wt./wt.) CuO/ZnO instead of deionized water, COP values of 4.31 and 4.44 were obtained, respectively.
