Abstract

An airborne particle collection system includes an airflow directing unit, register units, a fan unit, and a control system. The airflow directing unit includes a plurality of separately controlled air distribution segments. Each register unit includes a motorized damper and filter. The fan unit is connected to the airflow directing unit and to the register units through piping. The fan unit injects air into the airflow directing unit, and generates a vacuum force that causes exhaust air with airborne particles to be pulled into the register units and filtered by the filters within the register units. The control system selectively controls the air distribution segments of the airflow directing unit and the motorized dampers of the register units to generate alterable airflow patterns between the airflow directing unit and the register units in different zones within a room in which the airflow directing unit and the register units are disposed.

First claim

What is claimed is:

1. A method for collecting airborne particles, comprising:
injecting air into an airflow directing unit comprising a primary air tube, and a plurality of separately controlled air distribution segments connected to the primary air tube, wherein each air distribution segment comprises an airflow control valve connected to the primary air tube, an air distribution channel connected to an output of the airflow control valve, and a series of air exits holes aligned to the air distribution channel;
generating a vacuum force that causes exhaust air with airborne particles to be pulled into one or more register units, wherein each register unit comprises a motorized damper and a filter;
filtering the exhaust air using the filters of the one or more register units; and
sequentially activating the airflow control valves of the air distribution segments and the motorized dampers of the register units in a programmed activation sequence to generate alterable airflow patterns between the airflow directing unit and the register units in a plurality of different zones within a room;
wherein the plurality of different zones within the room comprise n sequentially adjacent zones; and
wherein the sequential activation of the airflow control valves of the air distribution segments and the motorized dampers of the register units creates air flow within the plurality of different zones in a repeated sequence which comprises a first sequence from a first zone to an n th zone followed by a second sequence from the n th zone to the first zone.

2. The method of claim 1 , wherein injecting air and generating a vacuum comprises automatically activating a fan unit, which is connected to the airflow directing unit and to the one or more register units through piping, to forcibly inject air into the airflow directing unit, and to generate the vacuum force in the piping connected to the one or more register units.

3. The method of claim 1 , wherein filtering comprises electrostatically filtering the exhaust air that is pulled through the one or more register units.

4. The method of claim 1 , wherein sequentially activating the airflow control valves of the air distribution segments comprises sequentially activating one of the airflow control valves of the airflow directing unit so that air is emitted from one of the air distribution segments at a given time, and wherein sequentially activating the motorized dampers of the one or more register units comprises sequentially activating the motorized dampers of the one or more register units so that only one damper of a given register unit is open at a given time.

5. The method of claim 4 , wherein each airflow control valve and motorized damper is activated for a period of about two seconds to about one minute.

6. The method of claim 1 , further comprising:
injecting ionized air into the airflow directing unit, wherein the ionized air comprises electrically charged air molecules; and
applying an electrical charge to the filters of the one or more register units, which is opposite to the electrical charge of the air molecules.

7. The method of claim 6 , further comprising programming a control system to automatically adjust an amount of ionization of the ionized air.

8. The method of claim 6 , further comprising programming a control system to automatically adjust an amount of electrical charge applied to the filters.

9. The method of claim 1 , wherein the airflow directing unit is disposed adjacent to a first wall in the room and wherein the register units are disposed adjacent to a second wall in the room, opposite the first wall.

10. The method of claim 1 , wherein the airflow directing unit comprises a shape of a decorative floor or ceiling molding.

11. The method of claim 10 , wherein the decorative floor or ceiling molding is formed of a composite material and wherein the primary air tube, the airflow control valves, and the air distribution channels are encapsulated within the composite material.

12. The method of claim 11 , wherein the air exit holes of the airflow directing unit comprise perforations that are formed in a front surface of the composite material.

13. An article of manufacture comprising a computer readable storage medium having program code embodied therewith, wherein the program code is executable by a computer to cause the computer to perform method steps for controlling an airborne particle collection system, the method steps comprising:
causing air to be injected into an airflow directing unit comprising a primary air tube, and a plurality of separately controlled air distribution segments connected to the primary air tube, wherein each air distribution segment comprises an airflow control valve connected to the primary air tube, an air distribution channel connected to an output of the airflow control valve, and a series of air exits holes aligned to the air distribution channel;
causing a vacuum force to be generated, which causes exhaust air with airborne particles to be pulled into one or more register units, wherein each register unit comprises a motorized damper and a filter, and filtered using the filters of the register units; and
sequentially activating the airflow control valves of the air distribution segments and the motorized dampers of the register units in a programmed activation sequence to generate alterable airflow patterns between the airflow directing unit and the register units in a plurality of different zones within a room;
wherein the plurality of different zones within the room comprise n sequentially adjacent zones; and
wherein the sequential activation of the airflow control valves of the air distribution segments and the motorized dampers of the register units creates air flow within the plurality of different zones in a repeated sequence which comprises a first sequence from a first zone to an n th zone followed by a second sequence from the n th zone to the first zone.

14. The article of manufacture of claim 13 , wherein injecting air and generating a vacuum comprises automatically activating a fan unit, which is connected to the airflow directing unit and to the one or more register units through piping, to forcibly inject air into the airflow directing unit, and to generate the vacuum force in piping connected to the one or more register units.

15. The article of manufacture of claim 13 , wherein filtering comprises electrostatically filtering the exhaust air that is pulled through the one or more register units.

16. The article of manufacture of claim 13 , wherein sequentially activating the airflow control valves of the air distribution segments comprises sequentially activating one of the airflow control valves of the airflow directing unit so that air is emitted from one of the air distribution segments at a given time, and wherein sequentially activating the motorized dampers of the one or more register units comprises sequentially activating the motorized dampers of the one or more register units so that only one damper of a given register unit is open at a given time.

17. The article of manufacture of claim 16 , wherein each airflow control valve and motorized damper is activated for a period of about two seconds to about one minute.
