Improving Coefficient Of Performance Using Heat Exchanger

Abstract

The system was charged with Freon gas (R-134a) and operated under two distinct conditions: first, with the integration of a heat exchanger, and second, without it. To ensure the retention of the refrigerant within the system, the valves were securely closed. This study elucidates the role of the heat exchanger in enhancing the performance of the compression refrigeration cycle. For the condition without the heat exchanger, the valves were closed following 30 minutes of operation with the heat exchanger to stabilize the system. Subsequently, the recorded data were mapped onto the pressure-enthalpy (p-h) chart to compute key performance metrics, including the cooling capacity, compressor energy input, and the coefficient of performance (COP). The analysis of COP values demonstrated a marked improvement in cycle efficiency when the heat exchanger was utilized, with superior performance metrics compared to the system operating without it.
