Air conditioning system with an electric motor driven supercharger

摘要

An air conditioning system (10) includes an air conditioning pack (16) 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 (14) that is fluidly connected to the air conditioning pack (16) for providing air to the air conditioning pack (16). The compressed air system (14) includes a compressor (18) driven by an electric motor (20). The electric motor (20) is commanded by a controller (12) to provide pressurized air when needed. In particular, the controller (12) commands the electric motor (20) based upon a desired conditioned airflow that is to be provided by the air conditioning pack (16). For high altitude aircraft, applications, a diffuser (24) is used to increase the efficiency of the compressor within the compressed air supply system.
