Abstract:
A user-programmable media dispensing system for use in a central or zoned forced-air heating, ventilating and air-conditioning system comprising:dispensing means actuable in response to a dispenser activating control signal to discharge a quantity of a medium into an air stream of a central or zoned forced-air heating, ventilating and air-conditioning system; a dispensing system central processor coupled to said dispensing means and generating a dispenser activating control signal to said dispensing means in response to instruction input signals coupled to said dispensing system central processor from user-programmable data entry; said dispensing means including a plurality of dispensing media containing reservoirs coupled in fluid communication with a media dispenser; said media dispenser being positioned in the air stream of a central or zoned forced-air heating, ventilating and air-conditioning system for dispensing the media contained in at least one of said dispensing media containing reservoirs into said air stream in response to said dispenser activating control signal generated by said dispenser system central processor; each one of said plurality of dispensing media containing reservoirs including a media output discharge control valve coupled in fluid communication between said dispensing media containing reservoir and said media dispenser for receiving said dispenser activating control signal generated by said dispenser system central processor to selectively control the discharge of dispensing media therethrough; user-programmable data entry coupled to said dispensing system central processor for entry of user-generated instructions and coupling said user-generated instructions as instruction input signals to said dispensing system central processor for generating said dispenser activating control signals to actuate said dispensing means; air stream sensor means positioned in the air stream of a central or zoned forced-air heating, ventilating and air-conditioning system and coupled to said dispensing system central processor for generating ambient-air-determined control signals to said dispensing system central processor to control the generation of said dispenser activating control signals to actuate said dispensing means; and a dilution manifold in fluid communication with said media dispenser and each one of said media output discharge control valves to receive and dilute the dispensing media discharged through said output discharge control valves prior to passing to said media dispenser.
