Nano Fluids used in VCRS: A Review

Abstract

This study highlights the utilization of nano-particle fluids as the refrigerants in the conventional vapour compression based thermal systems due to their super improvement in thermo-physical properties together with heat transfer capacity to enhance performance of the system described by its COP and reliability of refrigeration system. Further, demanding situations of performance enhancement of system the usage of nano additive refrigerants had been presented. Lubricant oil is described as the important part inside the complete refrigeration system, typically for the operation characteristic of the compressor. Presently, a collection of research goes on inside the area of the nanoparticles like metals, carbon nanotubes or carbides and many more. Nano-lubricants are somewhat different form of nano-fluids that can be types of nanoparticles, lubricants are identified as typical agents in the fields of refrigeration. This paper is representing the utility of nanoparticles balanced in lubricating oils of refrigerating structures. The purpose of this research is to look at and locate what kind of lubricant oil works higher with nanoparticles in refrigeration. From the assessment of literature, it’s been found that nanoparticles blended with mineral oil offer improved performance than polyester oil.
