The Nanoparticle suspended refrigerants or nanorefrigerants have been under the researchers’ scrutiny from past few years now. It is a well-established fact that the addition of nanoparticle into the refrigerant leads to better boiling heat performance which consequently leads to a better and more energy efficient refrigeration system. But, the knowledge of the thermophysical properties of the nanorefrigerants is still in its infancy. This theoretical investigation is an attempt to provide a new insight into the thermophysical properties such as thermal conductivity, thermal diffusivity, viscosity, specific heat and density of R141b based nanorefrigerants. The thermal conductivity enhancement using various models and mechanisms have been evaluated, compared and discussed in this work. This investigation was carried out on Cu-R141b, CuO-R141b, Al-R141b and Al2O3-R141b nanorefrigerant. The particle diameter was set at 50 nm.
