Performance Analysis of Indirect Evaporative Cooling System using M-Cycle

This paper aims to improve the performance of direct evaporative coolers with the help of Maisotsenko cycle called M-cycle. A new indirect evaporative cooler with counter current heat/mass exchanger configuration in which the product air and working air are entirely separated was developed in this research by design and experimental investigation. A new heat/mass exchanger using counter current flow configuration was designed by modified �-NTU method in terms of geometrical sizes with operating conditions. The theoretical results indicates that the heat/mass exchanger achieve wet bulb and dew point effectiveness approximately 115.21% and 84.12% respectively. Based on theoretical results, a prototype of heat/mass exchanger was constructed and the result indicates that the wet bulb and dew point effectiveness of experimental prototype ranged from 49.04% to 107% and 33.92% to 75.37% respectively. It is also concluded that this system is suitable for regions with dry, mild and hot climate and water is use as cooling agent so the pollution is vomited compared to conventional mechanical vapour compression refrigeration in which refrigerant use as cooling agent.
