Abstract:
A temperature control system for an aircraft ventilation system, the aircraft ventilation system including an upstream ventilation system architecture and a downstream ventilation system architecture, the temperature control system comprising:an air duct arranged to receive a volume of ventilation air from an upstream ventilation system architecture of an aircraft ventilation system, to air being arranged to transfer the volume of air to a downstream ventilation system architecture of the aircraft ventilation system; at least one beater interposed within the duct, the at least one heater being arranged to heat the ventilation air; at least one temperature sensor in thermodynamic communication with the volume of air within the duct, the at least one temperature sensor being located downstream from the at least one heater, the at least one temperature sensor being arranged to determine actual temperature of the ventilation air; and a controller in electrical communication with the at least one heater and the at least one temperature sensor, the controller being programmed with a predetermined range of temperatures above the freezing point of water, the controller being arranged to control the heater responsive to a comparison of the temperature of the actual temperature of the ventilation air to the predetermined range of temperatures to maintain the actual ventilation air temperature within the predetermined range of temperatures such that formation of ice is minimized in the aircraft ventilation system.
