Abstract
ABSTRACT In the present study, an attempt has been made to carry out an experimental investigation on the variations in the performance of vapor compression refrigeration system (VCRS) with the application of magnetic configurations. Magnetic configurations used for the present work were pair of magnets (MC-1) and Halbach array (MC-2) with the magnetic field intensities of 3000 and 7200 Gauss, respectively. The coefficient of performance (COP) was first determined in the absence of a magnetic field and then with the application of magnetic configurations on the condenser liquid line. Experimental outcomes show that the performance of the VCRS is dependent on the magnetic field strength and the magnetization time for the given conditions. Under the same conditions, the COP of the system increased up to 8.38% for MC-1 using two magnetizers and 9.94% for MC-2 using one magnetizer. Finally, it was observed that the TEWI analysis for the MC-1 and MC-2 was lesser than the conventional system, which was in the range of 0.72–2.11% and 1.83–3.39%, respectively. From the results, it can be concluded that the application of the Halbach array is an effective, economical, and prominent way to improve the performance of the VCRS compared to the pair of magnets.
