Abstract
A conditioning system for recirculation air of an aircraft cabin includes an air cycle system in fluid communication with the aircraft cabin and configured to receive a recirculation airflow from the aircraft cabin and a mixing chamber disposed in fluid communication between the air cycle system and the aircraft cabin. The mixing chamber is configured to mix the recirculation airflow received from the air cycle system with a conditioned airflow received from an environmental control system pack of the aircraft.
Claims19
A conditioning system for recirculation air of an aircraft cabin, the conditioning system comprising:
- an air cycle system in fluid communication with the aircraft cabin and configured to receive a recirculation airflow from the aircraft cabin;
- and
- a mixing chamber disposed in fluid communication between the air cycle system and the aircraft cabin, the mixing chamber configured to mix the recirculation airflow received from the air cycle system with a conditioned airflow received from an environmental control system pack of the aircraft.
A conditioning system for recirculation air of an aircraft cabin, the conditioning system comprising:
- a compressor having a compressor inlet and a compressor outlet, the compressor inlet in fluid communication with the aircraft cabin, wherein the compressor is disposed to receive a recirculation airflow from the aircraft cabin;
- a turbine having a turbine inlet and a turbine outlet, the turbine outlet in fluid communication with the aircraft cabin, wherein the aircraft cabin is disposed to receive the recirculation airflow from the turbine;
- and
- a heat exchanger in fluid communication with each of the compressor and the aircraft cabin and configured to transfer thermal energy between a cabin discharge airflow received from the aircraft cabin and the recirculation airflow received from the compressor.
A method of supplying conditioned air to an aircraft cabin, the method comprising:
- conducting, in a cooling operation, a recirculation airflow received from the aircraft cabin through an air cycle system, the air cycle system comprising a compressor, a heat exchanger, and a turbine;
- and
- conducting, in the cooling operation, the recirculation airflow received from an outlet of the air cycle system to a mixing chamber;
- wherein the mixing chamber is configured to mix the recirculation airflow with a conditioned airflow received from an environmental control system pack of the aircraft to produce a cabin airflow for delivery to the aircraft cabin.
