Cop Enhancement Of Vcr System By Using Nanorefrigerant

Abstract

Refrigeration is the process of removal of heat from a space it is where it is unwanted and transferring the same to the surrounding environment. This is produced by evaporation of liquid refrigerant in VCR system.The coefficient of performance (COP) of VCR system is depends on the refrigeration effect and work required the rate of heat transfer or by reducing the compressor work.It has been found that nanorefrigerant have much higher and strongly temperature dependent thermal conductivity than conventional refrigerant and it improve the thermo-physical properties. This can be considered as one of the key parameter of enhanced performance for refrigeration system. For this project we will use R134a as a base refrigerant and the R600a (Nano refrigerant) will be added to study its effect on COP. The R600a will be added at different proportions such as 0.5%, 1.0% and 1.5%. Based on the results most suitable proportion of nano refrigerant will be suggested.
