Energy Recovery on Environmental-Control-System of Aircraft with Electric-Turbo-Compressor

Abstract

In a general electric Environmental-Control-System(ECS), the conditioned air supplied inside the cabin of aircraft is discharged outside without being effectively used. The air passed through the cabin obtains a non-negligible amount of heat from electronic devices and passengers. Therefore, in this research, we propose the use of an electric turbo compressor that recovers energy with a turbine and returns power to the electric compressor before discarding air. We will investigate a thermo dynamic analysis to obtain the energy recovery rate under the configuration with two electric turbo compressor.
