An improved humidification system for jet-powered commercial aircraft comprising an evaporator adapted to add moisture to a gas flow, a gas flow control system for applying to the evaporator a gas flow having an internal energy sufficient to vaporize the moisture and a temperature measuring system for measuring the temperature of the gas flow exiting from the evaporator for regulating the amount of moisture added to the gas flow so as to maintain the evaporator exit temperature constant is disclosed. In a particular embodiment, the humidification system consists of a tank having an outlet duct adapted to deliver moisturized air to the passenger compartment of the aircraft, a water injection system adapted to flow water into the tank upon the temperature within the outlet duct rising above a preselected value and to terminate water flow upon the temperature falling below the preselected value, and a gas flow control system coupled to the tank and adapted to control the flow of air into the tank at a rate such that the air has sufficient internal energy to vaporize the water. An evaporator plate system is incorporated within the tank to ensure that all the injected water is vaporized before exiting the tank. Additionally, a demisting filter is mounted between the evaporator plate system and the outlet duct to ensure that all particulate matter is removed from the moisturized air before leaving the tank.

A system for controlling the humidity within the passenger compartment of an aircraft, the aircraft having a source of high temperature, pressurized air and a source of pressurized water, comprising: a tank having an outlet duct connected to said passenger compartment of said aircraft; water injection means comprising: a water injection nozzle mounted within said tank; pipe means connecting said source of pressurized water to said water injection nozzle; and valve means mounted in said pipe means between said water injection nozzle and said the source of pressurized water; a thermistor mounted in said outlet duct of said tank and adapted to sense the temperature within said outlet duct and to have a change in resistance as a function of said temperature; relay means coupled to said thermistor and said valve means and adapted to sense the change in resistance of said thermistor and to actuate said valve means to the open position upon said temperature within said outlet duct rising above a preselected value and to close said valve means upon said temperature falling below said preselected value; airflow control means comprising: an air injection nozzle mounted within said tank; pipe means connecting said source of high temperature air to said air injection nozzle; a temperature-biased pressure regulator for controlling airflow into said tank such that said airflow has an internal energy sufficient to vaporize said water injected into said tank; evaporator means mounted within said tank between said outlet duct and said air injection and said water injection nozzles, said evaporator means adapted to maintain said water within said tank until said water has been vaporized; and a demisting filter mounted in said tank between said evaporator means and said outlet duct, said filter adapted to prevent particulate matter from leaving said tank.
