ANALYSIS OF AN ORC USING R245fa UNDER THE OPTIMUM DESIGN WORKING CONDITION OF CONDENSER

Abstract

This scientific paper presents a comprehensive performance analysis of an Organic Rankine Cycle (ORC) used for heat waste recovery. The study investigates the influence of condenser design on the overall performance of the (ORC) system. To achieve this, the R245fa refrigerant is chosen as the working fluid due to its advantageous properties, rendering it a suitable choice for this specific application. Through detailed analysis, the paper provides insights into the efficiency and effectiveness of the (ORC) system, shedding light on the significance of condenser design in optimizing its performance. The conclusion of the study provides an in-depth analysis of the ORC system using R145fa as the working fluid. The performance analysis considers ideal conditions and real conditions with pressure drops across heat transfer components. The design procedure for the shell and tube horizontal condenser is thoroughly explained, and eleven condenser designs are evaluated against design limitations. The optimal condenser design is chosen based on these limitations and minimum surface area. The study concludes that the overall performance of the ORC system in real conditions is lower due to pressure drop effects. The findings emphasize the crucial role of careful condenser design in improving the performance, efficiency, and cost-effectiveness of ORC systems, thus influencing investment choices.
