ABSTRACT:
An inventive air conditioning system includes an air conditioning pack for receiving pressurized air and converting the pressurized air into conditioned air for an aircraft. Pressurized air is provided by a compressed air supply system that is fluidly connected to the air conditioning pack for providing air to the air conditioning pack. The compressed air system includes a compressor driven by an electric motor. The electric motor is commanded by a controller to provide pressurized air when needed. In particular, the controller commands the electric motor based upon a desired conditioned airflow that is to be provided by the air conditioning pack. For high altitude aircraft, applications, a diffuser is used to increase the efficiency of the compressor within the compressed air supply system.
