EFFECT OF NANOREFRIGERANT ON PERFORMANCE OF VCR SYSTEM: A REVIEW

Mechanical Engineering

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. Recently it is found that the use of nanotechnology in the refrigeration system can increase the performance of system. In this technique the nanoparticles are added in to the base fluid which is refrigerant or compressor oil (lubricating oil). It also 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 will first find all the available nanoparticles and we will also find their all properties and cost. After collecting all these data we will select one of the most suitable nanoparticles and mix them at proper concentration. This project is performed in order to check and clarify the effect of nanorefrigerant properties on heat transfer compared to pure refrigerant in refrigeration system.
