An entropy generation analysis method based on the second law of thermodynamics was used to component level optimization design of aircraft environmental control system in this paper. Through analyzing the air flow process in environmental control system, the function relationship between system entropy generation and present initial conditions was achieved. Along with the heat exchanger design calculation process, as the bleed air pressure and cabin design temperature change, the effect of the ratio between the heat exchanger heat side flow length, cold side flow length and height on whole system entropy generation was obtained. The results obtained in this paper have some guidance function on aircraft environmental control system optimum design.
