Evaluating the Performance of Vapor Compression Cycle by Adding Nanoparticle

Abstract

The discusses the improvements in refrigeration systems using nano-refrigerants or nanofluids.It explores the compatibility, stability, and feasibility of using nanofluids in refrigeration systems, and how the performance of Al2O3 nanoparticle-based nanofluids can enhance the efficiency of vapor compression refrigeration systems. Additionally, it discusses a study on the impact of polyester oil-based multiwalled carbon nanotube nano lubricants on both the evaporator's heat dissipation and the compressor's power consumption in a refrigerator. One ofthe potential heat transfer fluids in refrigeration systems is nano refrigerant, which can significantly improve the performance of vapor compression refrigerator systems. The study found that including nanoparticles in the refrigerant increases viscosity, thermal conductivity, and density, leading to enhanced heat transfer coefficients of performance and a reduction in power consumption.
