Vapor compression refrigeration systems (VCRS) are among the most widely utilized refrigeration technologies worldwide, with significant research efforts dedicated to enhancing their performance. A key strategy for improvement lies in optimizing the efficiency of the condenser. This study focused on analyzing VCRS condensers by evaluating three critical properties: condenser exit temperature, pressure drop, and heat flux. The research tested condensers made from four different materials—aluminum, copper, steel, and nickel—using the refrigerant R134a. Based on the findings, a performance ranking of the materials was established.
