Description
- The present disclosure relates generally to air filtration and purification, and more particularly, to a method and apparatus for processing air.
- Concern over air quality has triggered some developments in the area of indoor air quality improvement and/or control. Such developments have typically resulted in the production of various types of air processing systems including air filtration systems. Air filtration systems are sometimes differentiated according to air filtering capabilities and may include air filtration devices designed to be integrated within a heating, ventilation, and air conditioning (HVAC) system and local or unitary air filtration devices. Air filtration devices configured to be integrated with HVAC systems (i.e., integrated air filtration devices) are typically capable of filtering large amounts of ambient air such as, for example, an amount of ambient air that fills a warehouse, an office building, an apartment building, a house, an entertainment hall, etc. In contrast, local or unitary air filtration devices are typically configured to filter an amount of ambient air associated with a local area such as, for example, an office, a bedroom, a bathroom, etc.
- Air filters in existing air filtration devices maybe inefficiently used because of the angle at which ambient air enters and is drawn through the air filters. In particular, in some cases only a relatively small area or space of an air filter is used effectively to trap particles while the rest of the air filter remains unused. As a result, the maintenance cost of air filtration devices may increase because air filters may be prematurely replaced and/or air flow throughput may decrease because the air filtration devices may be frequently turned off for cleaning of the air filters.

Thus, a cross section view of the air flow from the chamber is substantially the same as the surface area of the receiving portion of the filter assembly. By distributing a volume of ambient air over a greater portion of the front of the filter assembly, the air filters of the filter assembly are used in a relatively efficient manner, and the maintenance cost of the filter assembly may be reduced.
- Referring to
FIG. 1 , anair processing system 100 configured in a known manner typically includes ahousing 110, anair flow guide 120, afilter assembly 130, and afan 140. In general, theair processing system 100 receives ambient air from anintake vent 150 of thehousing 110 into apassage 160. Theair flow guide 120 is configured to divert or guide the ambient air through thepassage 160 and into achamber 170 of thehousing 110. Thefilter assembly 130 includes one or more air filters 122, 124, and 126, to filter the ambient air from thechamber 170. Thefan 140 draws the ambient air from thechamber 170 into thefilter assembly 130 via areceiving surface 180 of thefilter assembly 130. Typically, thefan 140 immediately draws the ambient air from thepassage 160 into thefilter assembly 130 in a direction generally indicated byarrows 190. The air flow indicated by thearrows 190 does not permit thechamber 170 fill with ambient air prior to thefan 140 drawing the ambient air through thefilter assembly 130. - Turning to
FIG. 2 as an example, the ambient air is substantially filtered through a lower-center portion 210 of thereceiving surface 180 of thefilter assembly 130. The upper, left, and right portions, generally shown as 220, 230, and 240, respectively, of thereceiving surface 180 are substantially unused. Thus, each of the one or more filters of thefilter assembly 130 traps contaminants and, thus, becomes clogged in the lower-center portion 210. - Turning now to
FIG. 3 , a high velocityair processing system 300 configured in accordance with the teachings of the present disclosure is illustrated. The high-velocityair processing system 300 includes ahousing 310, a high-velocityair flow guide 320, afilter assembly 330, and afan 340. In general, the high-velocityair processing system 300 receives ambient air from anintake vent 350 of thehousing 310 via apassage 360. Theintake vent 350 may be configured to operate in combination with the high-velocityair flow guide 320 as described in detail below by enabling ambient air to flow into achamber 370 of thehousing 310 in a direction generally indicated byarrows 390. Theintake vent 350 may include a grate, a screen, and/or a large particle filter (none of which are shown). In one implementation, a layered configuration for theintake vent 350 may include the grate as the outermost layer followed by the screen, and the large particular filter as the innermost layer. The grate may be impact resistant to prevent damage to the screen, the large particle filter, and the portions of the high-velocityair processing system 300 located within thehousing 310. The screen may be configured to prevent relatively large objects (e.g., paper, coins, food, etc.) from entering into thehousing 310. The large particle filter may be configured to prevent relatively large particles (e.g., dust, hair, lint, liquid, etc.) from entering thehousing 310. - Although the
housing 310 is shown as having a relatively cubical structure, any other geometry or structure may be used to implement thehousing 310 including, for example, a pyramidal structure, a cylindrical structure, a trapezoidal structure, etc. In the illustrated example, however, thehousing 310 is cubical in shape and includes abottom panel 311A, a plurality ofupstanding side panels 311B, and atop panel 311C. Theintake vent 350 is approximately centrally located in thebottom panel 311A, thereby enabling air to be drawn into thechamber 370 through the bottom of thehousing 310. Thehousing 310 may include at least one vertical riser (not shown) upon which thehousing 310 sits, such that theintake vent 350 is elevated above a support structure of the housing (e.g. a floor), to allow air to flow into thechamber 370 through theintake vent 350. - The high-velocity
air flow guide 320 includes anupstanding portion 320A extending upward from thebottom panel 311A, and asupport portion 320B extending over and generally parallel to the face of thevent 350. Thesupport portion 320B is adapted to support thefilter assembly 330. As shown, thefilter assembly 330 is centrally located in thehousing 310 and rests upon thesupport portion 320B of the high-velocityair flow guide 320. While thefilter assembly 330 is shown as extending less than the distance between thesupport portion 320B and thetop panel 311C, thefilter assembly 330 and each individual filter within theassembly 330 may extend any amount between thesupport portion 320B and thetop panel 311C. - Also located with the
housing 310 is thefan 340. Thefan 340 is located to a side of thefilter assembly 330 opposite thechamber 370. Thefan 340 includes anoutput vent 342 located in thetop panel 311C. Theoutput vent 342 allows thefan 340 to draw air from thechamber 370 through thefilter assembly 330 and exhaust out thevent 342. - The
housing 310 may also include an access panel and/or a control panel (neither of which are shown). The access panel may be configured to enable access to thefilter assembly 330 and/or thefan 340 within thehousing 310 for maintenance, inspection, and/or any other purpose. The control panel may be mechanically and/or electrically coupled to thehousing 310 and configured to provide data input and output capabilities for controlling and/or monitoring any aspect of the high-velocityair processing system 300. For example, the control panel may be used to control operational states of the high-velocityair processing system 300. In addition, the control panel may be used to access status information associated with operations and/or status of the high-velocityair processing system 300. - The
support portion 320B of the high-velocity air flow guide 320 (e.g., an air flow guide) includes afirst portion 322 and asecond portion 324. The high-velocityair flow guide 320 may be implemented using plastic, metal, and/or other suitable material. Thefirst portion 322 is configured to receive ambient air from the intake vent 350 (i.e., an intake structure) and form thepassage 360 in conjunction with theintake vent 350. Thesecond portion 324 is configured to accelerate the ambient air from thepassage 360 into achamber 370 of thehousing 310 to generate a high-velocity air flow in a direction generally indicated by thearrows 390. In particular, thesecond portion 324 diverts or guides the ambient air into thechamber 370 so that the ambient air is generally evenly distributed relative to a receivingsurface 380 of thefilter assembly 330 as thefan 340 draws the ambient air from thechamber 370 through thefilter assembly 330. Thesecond portion 324 may be, for example, a radial portion or curved lip to accelerate the ambient air into thechamber 370 in the manner shown and described. For example, the air traveling through thepassage 360 may accelerate over the radialsecond portion 324 so that the speed of the air after the radialsecond portion 324 is greater than the speed of the air in thepassage 360. - Referring now to
FIG. 4 , in this example, thesecond portion 324 diverts or guides the ambient from thepassage 360 into thechamber 370 so that more area of the receivingsurface 380 of thefilter assembly 330 is used. By distributing the ambient air more evenly throughout the receivingsurface 380, thesecond portion 324 increases air flow throughput. In contrast to the receivingsurface 180 shown inFIGS. 1 and 2 for example, thesecond portion 324 diverts ambient air from thepassage 360 and accelerates air flow of the ambient air into thechamber 370 prior to thefan 340 drawing the ambient air through thefilter assembly 330. Thus, the time between filter replacements or cleanings may be extended. For example, thefilter assembly 330 may be rated for operation based on an amount of time or a volume of air that is processed. In particular, thefilter assembly 330 may be rated to operate for a predetermined amount of time (at a constant flow) before needing to be replaced or cleaned. Alternatively, thefilter assembly 330 may be rated to operate for a predetermined total volume of air before needing to be replaced or cleaned. By increasing the life of thefilter assembly 330, maintenance costs may be reduced. - Although the high-velocity
air flow guide 320 is depicted inFIG. 3 as a single, integrated structure, theupstanding portion 320A and thesupport portion 320B including thefirst portion 322 and thesecond portion 324 may be separate structures operatively coupled to each other. For example, thesecond portion 324 may be a separate structure, adjustably coupled to thefirst portion 322 so that thesecond portion 324 may be adjusted to increase/decrease the second air flow speed. For instance, thesecond portion 324 may be flexibly or pivotally attached to thefirst portion 322. - The
filter assembly 330 may include a plurality of air filter elements, generally shown as afirst filter 332, asecond filter 334, and athird filter 336 to process the ambient air from thechamber 370. For example, thefirst filter 332 may be a pre-filter, thesecond filter 334 may be a High Efficiency Particulate Accumulator (HEPA) filter, and thethird filter 336 may be a charcoal filter. In particular, thefirst filter 332 may be an electrostatic filter or a pleated filter having antimicrobial properties. Thefirst filter 332 may be used to pre-filter the ambient air that is drawn into thehousing 310 via theintake vent 350 to remove relatively large pollutants or particles (e.g., dust, lint, etc.) from the ambient air. The HEPA filter used to implement thesecond filter 334 may be used to capture many bacteria, viruses, allergens (e.g., pollens, spores, smoke, etc.), and other relatively small organisms or particles that may be found in ambient air. The charcoal filter used to implement thethird filter 336 may be used to remove volatile organic compounds (VOC) (e.g., certain chemicals, gases, etc.) and odors from the ambient air. - Although the
filter assembly 330 is depicted inFIG. 3 to include three filters, thefilter assembly 330 may include more or fewer filters. Further, the illustratedfilter assembly 330 is positioned so that the receivingsurface 380 of thefilter assembly 330 is substantially perpendicular relative to theintake vent 350. That is, the receivingsurface 380 is parallel to a plane that is substantially perpendicular to theintake vent 350. In this manner, the ambient air is drawn into thehousing 310 by thefan 340 via theintake vent 350 in a direction generally indicated byarrows 390. Alternatively, thefilter assembly 330 may be skewed at an angle relative to theintake vent 350. For example, the receivingsurface 380 may be parallel to a plane that intersects theintake vent 350 at an angle other than perpendicular. Further, one filter of thefilter assembly 320 may be disposed in a first position relative to theintake vent 350 and another filter of thefilter assembly 330 may disposed in a second position relative to theintake vent 350. For example, thefirst filter 332 may be skewed at an angle relative to theintake vent 350, whereas thesecond filter 334 may be substantially perpendicular relative to theintake vent 350. - The
fan 340 may be a squirrel cage fan, or any other type of fan configured to draw ambient air from theintake vent 350 into thehousing 310 through thefilter assembly 330 and push or exhaust processed air out of thehousing 310 through thevent 342. Thefan 340 may be a variable speed fan communicatively coupled to and controlled by aninformation processing system 390 via alink 392. For example, the speed of thefan 340 may be controlled based on information received by theinformation processing system 390. - The
information processing system 390 may be implemented using any processing system, including, by way of example, a computer, an application specific integrated circuit (ASIC), a processor system or other suitable device. In this example, theinformation processing system 390 is aprocessor system 2000 illustrated inFIG. 5 and configured to control and/or monitor operations of the high-velocityair processing system 300. Theinformation processing system 390 may be communicatively coupled to the control panel (not shown) and configured to receive commands entered via the control panel by a person. In addition, theinformation processing system 390 may be configured to display information via the control panel, or other suitable display. - The method and apparatus disclosed herein may be integrated within devices such as, for example, a kiosk, an information booth, an automated teller machine, a public telephone, an advertisement apparatus, a computer terminal, etc. to process ambient air.
-
FIG. 5 is a block diagram of anexample processor system 2000 adapted to be implemented as theinformation processing system 390. Theprocessor system 2000 may be, for example, a desktop computer, a personal computer, a dedicated computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a server, an Internet appliance or any other type of computing device. - In this example, the
processor system 2000 illustrated inFIG. 5 includes achipset 2010, which includes amemory controller 2012 and an input/output (I/O)controller 2014. As is well known, a chipset typically provides memory and I/O management functions, as well as a plurality of general purpose and/or special purpose registers, timers, etc. that are accessible or used by aprocessor 2020. Theprocessor 2020 is implemented using one or more processors. Theprocessor 2020 includes acache 2022, which may be implemented using a first-level unified cache (L1), a second-level unified cache (L2), a third-level unified cache (L3), and/or any other suitable structures to store data. - As is conventional, the
memory controller 2012 performs functions that enable theprocessor 2020 to access and communicate with amain memory 2030 including avolatile memory 2032 and anon-volatile memory 2034 via abus 2040. Thevolatile memory 2032 may be implemented by Synchronous Dynamic Random Access Memory (SDRAM), Dynamic Random Access Memory (DRAM), RAMBUS Dynamic Random Access Memory (RDRAM), and/or any other type of random access memory device. Thenon-volatile memory 2034 may be implemented using flash memory, Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), and/or any other desired type of memory device. - The
processor system 2000 also includes aninterface circuit 2050 that is coupled to thebus 2040. Theinterface circuit 2050 may be implemented using any type of well known interface standard such as an Ethernet interface, a universal serial bus (USB), a third generation input/output interface (3GIO) interface, and/or any other suitable type of interface. Additionally, theinterface 2050 may couple the processing system to thefan 240 via thelink 392. - One or
more input devices 2060 are connected to theinterface circuit 2050. The input device(s) 2060 permit a user to enter data and commands into theprocessor 2020. For example, the input device(s) 2060 may be implemented by a keyboard, a mouse, a touch-sensitive display, a track pad, a track ball, an isopoint, and/or a voice recognition system. - One or
more output devices 2070 are also connected to theinterface circuit 2050. For example, the output device(s) 2070 may be implemented by display devices (e.g., a light emitting display (LED), a liquid crystal display (LCD), a cathode ray tube (CRT) display, a printer and/or speakers). Theinterface circuit 2050, thus, typically includes, among other things, a graphics driver card. - The
processor system 2000 also includes one or moremass storage devices 2080 to store software and/or data. Examples of such mass storage device(s) 2080 include floppy disks and drives, hard disk drives, compact disks and drives, and digital versatile disks (DVD) and drives. - The
interface circuit 2050 also includes a communication device such as a modem or a network interface card to facilitate exchange of data with external computers via a network. The communication link between theprocessor system 2000 and the network may be any type of network connection such as an Ethernet connection, a digital subscriber line (DSL), a telephone line, a cellular telephone system, a coaxial cable, etc. - Access to the input device(s) 2060, the output device(s) 2070, the mass storage device(s) 2080 and/or the network is typically controlled by the I/
O controller 2014 in a conventional manner. In particular, the I/O controller 2014 performs functions that enable theprocessor 2020 to communicate with the input device(s) 2060, the output device(s) 2070, the mass storage device(s) 2080 and/or the network via thebus 2040 and theinterface circuit 2050. - While the components shown in
FIG. 5 are depicted as separate blocks within theprocessor system 2000, the functions performed by some of these blocks may be integrated within a single semiconductor circuit or may be implemented using two or more separate integrated circuits. For example, although thememory controller 2012 and the I/O controller 2014 are depicted as separate blocks within thechipset 2010, thememory controller 2012 and the I/O controller 2014 may be integrated within a single semiconductor circuit. - In one example of operation, the
processor system 2000 may control the speed of thefan 340 to process air through theair processing system 300. For instance, theprocessor system 2000 may start thefan 340, causing air to be drawn into thesystem 300. Thesystem 300 receives the ambient air from theintake vent 350 of thehousing 310 wherein the ambient air is diverted by theair flow guide 320 in thechamber 370 through thepassage 360. Theair flow guide 320 accelerates the air flow from a first air flow speed to a greater second air flow speed as thesecond portion 324 of thesupport portion 320B diverts the air into thechamber 370. Thesecond portion 324 diverts or guides the ambient air from thepassage 360 into thechamber 370 so that more area of the receivingsurface 380 of thefilter assembly 330 is used. For instance, a cross sectional view of the air flow from thechamber 370 onto thefilter assembly 330 is substantially the same as the area of the receivingsurface 380 of thefilter assembly 330. From there, the ambient air travels through thefilter assembly 330, into thefan 340, and exhausts out thevent 342 as processed and filtered air. - Although certain example methods and apparatuses have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all embodiments and modifications falling within the scope of the appended claims either literally or under the doctrine of equivalents.
