The classification and preparation of nanofluids are introduced. The thermophysical properties of nanofluids such as thermal conductivity, convective heat transfer coefficient and viscosity are reviewed. The study of nanofluids in refrigeration and cooling applications are focused, such as the nanofuids added in phase change materials can improve the heat transfer effect, and the heat transfer are improved inside micro-tube or micro-heat transfer. It is pointed out that the nanofluids has a good application prospect in refrigeration and cooling.
