Abstract:


Background: Nowadays the era is of saving energy by working in an efficient and effective manner. As the temperature of atmosphere increases globally there is a keen demand for vapor compression refrigeration system among people, especially in a region which have a fervent climaticconditions. The technology is advancing day by day, thus by using vapor compression refrigeration system efficiently is a way to contribute in saving energy.

Objective: Previously a lot of work is carried out to boost the performance by changing the design of the evaporator, using different refrigerants and by adopting different methods. We are now being equipped with nanotechnology in the field of refrigeration in a better way as it was earlier, nano fluids have far better heat transfer properties as compared to vintage fluid.

Method:In this paper, performance improvement of a vapor compression refrigeration system has been accomplished by using Al2O3, TiO2 and CuO nanoparticles in the deionised water (DIW) as base fluid. Three different concentrations 0.01%, 0.005% and 0.001% by wt. of oxide nanoparticles have been used at three different operating temperatures i.e 29°C, 33°C and 37°C.

Results: The results showed that CuO nanofluids shows better performance as compared to Al 2O3, TiO2 nanofluids and normal water.

Conclusion: CuO nanofluids shows better results as compared to Al2O3, TiO2 nanofluid and normal water. Therefore we should prefer CuO nanofluid to save power consumption.
