Özet

One of the effective ways to increase performance in Diffusion Absorption Refrigeration (DAR) system is the use of nanoparticles. In this study, the effect of CuO and TiO2 nanoparticles added 0.68 wt% to a DAR system using ammonia-water-helium as the working fluid on the energy loss and exergy destruction occurring in each equipment of the system, energy and exergy efficiencies was experimentally investigated. It has been observed that the TiO2 nanoparticle reduces the operating pressure of the system, while the CuO nanoparticle does not have any effect on the system operating pressure. TiO2 and CuO nanoparticles increased the cooling capacity. While TiO2 and CuO nanoparticles increased the energy performance by 66.75% and 13.32%, respectively, they decreased the exergy performance by 17.53% and 3.42%, respectively.
