  • Flight crew and attendant rest environmental control system
    Patent number: 6619589
    Abstract: The present invention provides a temperature control system for an aircraft ventilation system that couples with existing aircraft upstream ventilation system architecture and downstream ventilation system architecture. The temperature control system includes an air duct arranged to receive a volume of ventilation air from the upstream ventilation system architecture and transfer the volume of air to the downstream ventilation system architecture. A heater is arranged to heat the ventilation air. A controller is arranged to control the heater responsive to a comparison of the actual temperature of the ventilation air to a desired range of temperatures. The controller maintains the actual ventilation air temperature within the predetermined range of temperatures such that formation of ice is minimized in the aircraft ventilation system. An exhaust shutoff valve between the air distribution system and the lavatory/galley ventilation system provides for ventilation in the event smoke is detected.
