Improvement in Cop of Refrigerator System by Using Nanofluid and Magnetic Field

EasyChair Preprint no. 2945

Abstract

This experimental investigation exemplifies the performance improvement by the effect of application of magnetic field to liquid line and addition of copper Nano particles to the compressor lubricating oil of vapour compression refrigeration system. The main benefit of this experimental investigation is improvement in COP by increasing refrigerating effect and decreasing compressor power input without usage of any external energy. The magnetic field strength was varied by increasing the number of magnetic pairs applied to the liquid line (from outlet of condenser to inlet of expansion valve). The COP was initially measured without application of magnetic field, and then magnetic field applied to liquid refrigerant was increased by increasing the number of the magnetic pairs from 1 to 5. Similarly The COP was initially measured without addition of copper Nano particles to refrigerant, and then adding copper Nano particles to the refrigerant was increased by increasing the percentage of volumetric addition of copper Nano particles were 0.01%, 0.015%, 0.02%, 0.025% to the refrigerant.
