<p>An environment control system for a body of an aircraft that provides controlled ventilation of the interior space of an aircraft body (1), facilitating reduction of volatile organic compounds (VOCs) within cabin air, dehumidifying and reducing moisture condensation and thus corrosion and other moisture related problems within the envelope (5), allowing increased humidification of cabin air, and allowing suppression of fires within the envelope. The environment control system includes at least a cabin (3) and an envelope (5). It includes supply means (23, 23a) for supplying a flow of dry ventilation air to the aircraft body (1). An airflow control device (13) is capable of dividing the flow of ventilation air into an envelope ventilation air stream (25) and a cabin ventilation air stream (26). An envelope ventilation duct system (14, 16, 27, 29) directs the envelope ventilation air stream (25) into the envelope (5), and a cabin duct system (20, 21) directs the cabin ventilation air stream (26) into the cabin (3). An anti-corrosion/sorption treatment (41) is applied to surfaces subject to condensation in the envelope (5). A return air control unit (17) is provided for selectively drawing return air from one of the envelope (5) and the cabin (3). The environment control system can be incorporated into new aircraft construction, or can be installed as a retro-fit into existing aircraft.</p> |
