Experimental Investigation on Refrigerator Using Air Cooled Condenser and Coolant Cooled Condenser

Abstract: The aim of this project was to investigate experimentally compare the effect of coolant-cooled condenser and air cooled condenser in a household refrigerator. The experiment was doing buy using refrigerant HFC134a as the refrigerant. In this the coolant cooled condenser is retrofitted with household refrigerator. Coolant used in the condenser is polyalkaline glycol. The pressure gauge and energy meter device was attached to the test rig. The temperature was measured by digital thermometer and all readings note at each load. The performance of the household refrigerator with air cooled condenser and coolant cooled condenser have been compared for different load conditions. The graph plotted by COP with load and work done with load. The results showing that the COP is greater when the system is working with coolant cooled condenser and work done by compressor is also reduced by coolant cooled condenser, thus the energy consumption can be reduced. The results indicate that the refrigerator performance had improved when coolant-cooled condenser was used instead of air-cooled condenser on all load conditions.
