Method and system for an integrated air filtering apparatus and thermal solar system using aspect ratio
View Patent ↗A solar energy system. The system includes a thermal solar system comprising an air plenum positioned between the system and the underside body. In a specific embodiment, the air plenum is configured according to a specified aspect ratio. The system uses an air moving device to transfer a volume of air through the plenum. The air moving device is configured to maintain a flow rate associated with the volume of air at a specified velocity. The air plenum is configured to reduce the particle concentration of the air traveling through the plenum and to undergo heat treatment for use inside the target building where the thermal solar system is implemented, which keeps the air entering the building clean and healthy.
1. A method for filtering air for use in a building structure, the method comprising:
transferring a volume of air through a plenum characterized by an aspect ratio of at least 5:1 and having a length of greater than 100 inches, the volume of air comprising a plurality of particles having a first particle concentration;
maintaining a flow rate associated with the volume of air at a linear velocity of less than about 3 feet per second as the volume of air traverses through the plenum; and
removing one or more of the plurality of particles from the volume of air using one or more portions of the plenum to reduce the first particle concentration to a second particle concentration, the second particle concentration being less than the first particle concentration.
2. The method of claim 1 wherein the plurality of particles comprise a particle size ranging from about 0.1 micron to about 400 microns.
3. The method of claim 1 wherein the plenum comprises an intake region and an exhaust region, the intake region and the exhaust region configured in an angled orientation relative to a direction of gravity.
4. The method of claim 1 wherein the plenum comprises an intake region and an exhaust region, the intake region having a first height relative to a ground and the exhaust region having a second height relative to the ground, the first height being less than the second height.
5. The method of claim 1 wherein the aspect ratio of the plenum L/W is greater than 5.
6. The method of claim 1 wherein the aspect ratio of the plenum L/W is greater than 10.
7. The method of claim 1 wherein the aspect ratio of the plenum L/W is greater than 15.
8. The method of claim 1 wherein the volume of air is characterized by a flow rate of about 500 CFM and less.
9. The method of claim 1 wherein the plenum comprises a metal material.
10. The method of claim 1 wherein the plenum comprises a polymer material.
11. The method of claim 1 wherein the removing of the one or more particles comprises subjecting the one or more particles to a gravitational force, the one or more particles having a size of greater than about 5 micron.
12. The method of claim 1 wherein the removing of the one or more particles comprises subjecting the one or more particles to a turbophoresis-inducing flow characteristic.
13. The method of claim 1 wherein the removing of the one or more particles comprises subjecting the one or more particles to be impacted to one or more portions of the plenum.
14. The method of claim 1 wherein the removing of the one or more particles comprises subjecting the one or more particles to a drag force induced by the volume of air.
15. The method of claim 1 wherein the plenum comprises a lower region, the lower region comprising one or more patterns configured to remove the one or more particles.
16. The method of claim 12 wherein the plenum comprises a lower region, the lower region comprising one or more patterns configured to increase the turbophoresis-inducing flow characteristic.
17. The method of claim 13 wherein the plenum comprises a lower region, the lower region comprising one or more patterns configured to increase the probability of particle impact on one or more portions of the plenum.
18. The method of claim 14 wherein the plenum comprises a lower region, the lower region comprising one or more patterns configured to increase the drag force induced by the volume of air on the particle.
