Apparatus and related method for selectively increasing the humidity in a predetermined zone

A method for increasing the humidity in a predetermined zone comprising:

• (a) sensing a predetermined selected condition in a predetermined zone;
• and
• (b) dispensing a composition consisting essentially of water and a liquid propellant from a portable apparatus into the predetermined zone when the pre-selected condition is sensed, the apparatus comprising a disposable, hand-held, aerosol-type container;
• an aerosol composition consisting essentially of water and a liquid propellant in the container;
• a valve comprising an inlet and an outlet for controlling the discharge of the aerosol composition from the container, the valve being biased in a non-discharging position and being movable to a discharging position, wherein the inlet of the valve is in communication with the container such that the aerosol composition can flow from the container through the valve;
• an actuator in fluid communication with the outlet of the valve such that the aerosol composition can flow from the outlet of the valve through the actuator and outwardly from the container, wherein movement of the actuator results in movement of the valve into a discharging position;
• means for mounting the pressurized container such that upon movement of the actuator, the valve is moved into the discharging position and the aerosol composition is dispensed from the pressurized container through the valve and actuator and into the predetermined zone;
• electrically-operable actuator comprising a solenoid mounted adjacent the actuator and an arm attached to the solenoid, the arm being moveable relative to the actuator between discharging and non-discharging positions, wherein when the arm is in the discharging position, the arm displaces the actuator and thereby moves the biased valve into the discharging position, and when the arm is in the non-discharging position, the arm is positioned to allow the biased valve to reside in the non-discharging position;
• and
• a sensor disposed in the predetermined zone and in electrical connection with the actuator for detecting a pre-selected condition in the predetermined zone, wherein when the sensor detects the pre-selected condition, the sensor signals the actuator to move the arm into the discharging position and thereby displace the pressurized container actuator so that the biased valve is moved into the discharging position, thereby providing the aerosol composition to be discharged as an aerosolized liquid into the predetermined zone,
• wherein the apparatus is capable of being transported as a unit from one predetermined zone to another predetermined zone and used to discharge aerosolized water into each such zone.
