Abstract

In this study, thermal properties of R134a/TiO₂ and R513a/TiO₂ such as thermal conductivity, density and dynamic viscosity , specific heat and convective heat transfer coefficient investigated. The TiO₂ nanoparticles are average size of 10 nm and volume concentration from 1% to 10%. The theoretical analyses show that the thermal properties of R513a/TiO₂ nanorefrigerant are better than R134a/TiO₂ nanorefrigerant.
