Performance Analysis of Domestic Refrigerators Condenser Coil By Applying Lampblack / Synthetic Black Blend
Year: 2023
Type: article
Abstract: : Domestic refrigerators are usually used for cooling the bounded space by absorbing the heat through the evaporator and simultaneously rejecting the heat to the surrounding through the condenser coil. The black color coated condenser coil is the main part that rejects heat to the surrounding in the form of radiations. Herein, to increase rejection of the heat from the condenser coil, to increase its performance, a blend of lampblack/ synthetic black (various w/w ratio) was partially painted on. The three different compositions (w/w) are applied on the condenser coil and accordingly, the heat radiating coefficient and coefficient of performance are measured. Optimized composition of lampblack /synthetic black (4:6) provided maximum performance in terms of coefficient of performance 5.51% and with heat transfer coefficient 16.11%. The results show a costeffective approaches to increase the performance as well as the life time.
