초록

An environmental control system includes an air cycle machine, an electrical machine coupled to the air cycle machine, and a controller for the electrical machine. The controller can cause electrical energy to be extracted from the electrical machine whenever cooling capacity and/or airflow rate of the air cycle machine are greater than necessary. The electrical machine can also be operated as a motor to increase the airflow rate and cooling capacity of the air cycle machine.
