Recent progress of nanorefrigerant development: a review

Abstract

Nan refrigerant is produced by blending nanoparticle in the refrigerant base. The purpose of nanoparticle in refrigerant base is to enhance the heat transfer performance, thus beneficial to any cooling application. This paper presents of a review of recent progress of nanorefrigerant development and its characterisation. Results of previous experiment of nanorefrigerant mixture which aim to enhance the heat transfer coefficient (HTC) are presented. Moreover, enhancement of heat transfer coefficient based on concentration, size of nanoparticle and type of nanoparticle used in experiment studies are also presented. In general, with the increment of nanoparticle concentration the viscosity is increased and instantaneous enhanced the thermos-physical properties such as thermal conductivity.
