System and method for continuously removing a particular type of gas molecules from a gas stream
View Patent ↗A method for continuously removing a particular type of gas molecules (“gas molecules”) from a gas stream includes selecting a liquid having an affinity for the gas molecules to be removed, and providing the selected liquid to each of a first and second mat, each mat formed from a plurality of fibers having the ability to retain the selected liquid within longitudinally extending channels having longitudinally extending openings against moving into the space between the individual fibers, the mats in fluid communication therebetween with the selected liquid. The method includes directing the gas stream through a portion of the first mat into contact with the selected liquid along the longitudinally extending openings whereby the selected liquid absorbs the gas molecules, and directing a second gas through a portion of the second mat so that the gas molecules, absorbed by and disbursed throughout the selected liquid, are stripped and carried away.
1. A heating, ventilating, and air conditioning (HVAC) system for continuously removing a predetermined type of gas molecules from a first air stream and releasing the predetermined type of gas molecules into a second air stream, the HVAC system comprising:
a first plurality of fibers and a second plurality of fibers disposed within the HVAC system, each comprising a longitudinally extending channel with a longitudinally extending opening, wherein the second plurality of fibers is positioned downstream of condenser coils of the HVAC system relative to the second air stream, and wherein the condenser coils are configured to heat the second air stream before the second air stream is directed through the second plurality of fibers;
a liquid having an affinity for the predetermined type of gas molecules disposed within the channels of the first plurality of fibers and the second plurality of fibers; and
a fan configured to direct the first air stream through the HVAC system and across at least a part of the first plurality of fibers into contact with the liquid along the longitudinally extending openings whereby the liquid is configured to absorb the predetermined type of gas molecules;
wherein the first plurality of fibers is fluidly coupled with a collector configured to collect the liquid, wherein the collector is separate from the first air stream, separate from the second air stream, or separate from the first air stream and the second air stream;
wherein the second plurality of fibers is fluidly coupled with the collector, wherein the first plurality of fibers and the second plurality of fibers are in fluid communication therebetween with the liquid in the collector, and wherein the second air stream is configured to strip and carry away the predetermined type of gas molecules.
2. The HVAC system of claim 1 , wherein the HVAC system selectably provides for a reversed flow direction of the predetermined type of gas molecules for continuously removing the predetermined type of gas molecules from the second air stream and releasing the predetermined type of gas molecules into the first air stream.
3. The HVAC system of claim 1 , wherein the HVAC system is configured to receive power from a renewable energy source, a waste heat energy source of the HVAC system, or a combination thereof to continuously release the predetermined type of gas molecules into the second air stream.
4. The HVAC system of claim 1 , wherein the HVAC system is configured to receive power from a renewable energy source comprising solar energy to continuously release the predetermined type of gas molecules into the second air stream.
5. The HVAC system of claim 1 , wherein the HVAC system is configured to receive power from a waste heat energy source that is generated by the condenser coils of the HVAC system during a cooling mode of the HVAC system to continuously release the predetermined type of gas molecules into the second air stream.
6. The HVAC system of claim 1 , wherein the predetermined type of gas molecules are selected from the group consisting of water vapor, carbon dioxide, organic compounds, or a combination thereof.
7. The HVAC system of claim 1 , wherein the first plurality of fibers and the second plurality of fibers each comprise a plurality of strands.
8. The HVAC system of claim 1 , wherein the first plurality of fibers is disposed in a first chamber of a first housing and the second plurality of fibers is disposed in a second chamber of a second housing.
9. The HVAC system of claim 8 , wherein the fan is a first fan configured to direct the first air stream within the first chamber, and wherein the HVAC system comprises a second fan configured to direct the second air stream within the second chamber.
10. The HVAC system of claim 1 , wherein the first plurality of fibers is positioned upstream of cooling coils of the HVAC system relative to the first air stream, and wherein the cooling coils and the condenser coils are part of a common refrigeration circuit.
11. The HVAC system of claim 1 , wherein the first plurality of fibers is positioned upstream of a return air inlet of a packaged rooftop unit of the HVAC system.
