Nano-refrigerants are a special class of nanofluids, prepared by addition of nanoscale impurity in refrigerants. The nano-refrigerants have a wide range of applications in many fields of thermal engineering including rapid refrigeration, air conditioning and heat pumps. In the present work, nanorefrigerants are prepared by forcefully dispersing Mono-, Bi- and Tri-layer graphene nanosheets in R134a refrigerant (as base fluid) at low temperature (278 K). To analyze the effect of number of layers of graphene, three types of graphene layers namely mono-, bi- and tri-layer graphene nanosheets are chosen. The result of the research work shows that thermophysical and heat transfer properties are strongly influenced by the number of layers of graphene. The nanorefrigerant prepared using mono-layer graphene shows outstanding heat transfer property in terms of ∼96.14 % enhancement in thermal conductivity over the pure refrigerant.
