Abstract
In this paper, energy and exergy analyses are performed on an aircraft air cycle machine. Air cycle machine is essential to ventilate aircraft cabin during commercial flights. Exergy destruction rates and energy parameters of each component are investigated at a designated aircraft cruise altitude which is 10,789 meters and ambient air that is −55 °C. The thermodynamic parameters used here to obtain the results are real ones from actual devices. Exergy flow supplied to the air cycle machine is found as 235.392 kW. Exergy destruction rate of primary heat exchanger is calculated as 33.839 kW. Exergy destruction rate of turbine, compressor, and secondary heat exchanger section is calculated to be 55.65 kW.
