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.
