CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S.
Provisional Patent Application No. 62/077,582, filed Nov. 10, 2014,
which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to a device for
eliminating air pockets, eliminating air stratification, minimizing
inconsistent temperature, and increasing internal air turns within
a facility.
[0004] 2. Description of the Prior Art
[0005] Systems, methods, and devices for air distribution and
circulation management within facilities are well-known in the
prior art. In particular, HVAC systems and area fans are well-known
in the prior art for distributing and circulating air within
facilities. Conventional HVAC systems introduce hot, cool, or
ventilation air into a facility--typically through a costly system
of ductwork or via ductwork to a diffuser box. Significant
temperature fluctuations are caused by walk and loading, doors,
windows, hot or cold walls, hot and cold roof, the number of
occupants, and equipment inside of a facility. Due to intermittent
run time and duct and diffuser box air distribution systems,
conventional systems tend to create air stratification and hot
zones. In effect, these systems are relying on the system fans,
with large hp motors, to generate intermittent air circulation.
Until the HVAC system restarts, still air develops into pockets of
different temperatures. This change in temperature, in addition to
hot and cold spots, creates bands of warm and cool air throughout a
facility, known as air stratification. A traditional HVAC system
runs when the air differential varies from the set temperature at
the thermostat location and turns off when the temperature reaches
what is called for on the thermostat. By design, a traditional HVAC
system is never at the exact `right` temperature, but works to stay
within a range of expected temperatures. Area fans also do not
eliminate air pockets or thermal stratification in a facility, nor
are they capable of minimizing temperature fluctuations in a
facility. Accordingly, a need exists for methods, systems, and
devices which sufficiently reduce or eliminate air pockets, thermal
stratification, and temperature fluctuations. These methods,
systems, and devices should be cost-effective, and allow for a
consistent temperature (within 2 degrees Fahrenheit of the desired
temperature) to be maintained.
[0006] One example of a prior art solution to the above-stated
problems can be found at: http://www.everairtech.com/solution.html.
This solution shows a unit with a simple fan encased in a
rectangular housing. Each unit requires a short supply and a return
duct from a package or split system HVAC unit.
[0007] Other relevant art includes the following US Patent
documents:
[0008] U.S. Patent Application Pub. No. 2010/0202932 for "Air
movement system and air cleaning system" by Danville, filed Feb.
10, 2010 and published Aug. 12, 2010, describes an air movement and
air cleaning system which includes an air movement system
preferably including fan and fan housing to prevent thermal
gradients in a building or room, in combination with an air
cleaning surface of at least titanium dioxide, to react with
moisture in the air and an ultraviolet light source in close
proximity to the air cleaning surface, such that as humidity in the
air passes through the air movement system over the titanium
dioxide, the ultraviolet light creates hydroxyl radicals in the
presence of the titanium oxide catalytic surface thereby purifying
the air that passes there through.
[0009] U.S. Pub. No. 2010/0291858 for "Automatic control system for
ceiling based on temperature differentials" by Toy, filed Jul. 28,
2010 and published Nov. 18, 2010, describes a fan which includes a
hub, several fan blades, and a motor that is operable to drive the
hub. A motor controller is in communication with the motor, and is
configured to select the rate of rotation at which the motor drives
the hub. The fan is installed in a place having a floor and a
ceiling. An upper temperature sensor is positioned near the
ceiling. A lower temperature sensor is positioned near the floor.
The temperature sensors communicate with the motor controller,
which includes a processor configured to compare substantially
contemporaneous temperature readings from the upper and lower
temperature sensors. The motor controller is thus configured to
automatically control the fan motor to minimize the differences
between substantially contemporaneous temperature readings from the
upper and lower temperature sensors. The fan system may thus
substantially destratify air in an environment, to provide a
substantially uniform temperature distribution within the
environment.
[0010] U.S. Pat. No. 6,955,596 for "Air flow producer for reducing
room temperature gradients" by Walker, et al., filed on Aug. 26,
2004 and issued on Oct. 18, 2005, describes an air flow producer
mounted at the ceiling of a room generates an air flow toward the
floor, reducing temperature gradients and improving heating and
cooling efficiency. A housing defines a circular cylindrical,
vertical flow passage that receives the air flow. A discharge
chamber discharges the air flow through a grill toward the floor.
The discharge chamber has a cross-section that expands
progressively from the outlet of the flow passage to the outlet of
the discharge chamber. The air flow through the housing is produced
by a fan with a rotary blade assembly, and the blade assembly
extends partially into the discharge chamber. The position of the
blade assembly and the expanding cross-section of the discharge
chamber cooperate to increase air flows through the housing.
Optionally, an air intake chamber of generally inverted
frustoconical shape may be mounted at the upper inlet end of the
cylindrical flow passage to smooth flows further.

DETAILED DESCRIPTION
[0043] None of the prior art addresses the longstanding need for
eliminating air pockets, eliminating air stratification, minimizing
inconsistent temperature, and increasing interior air turns in an
open ceiling or 20' clear drop ceiling environment independent of
traditional HVAC systems and system components, such as ducts.
Thus, there remains a need for methods, systems, and devices which
provide energy efficient air circulation to remove stratified air
columns and air pockets, and maintain a stable and consistent
temperature, namely within 2 degrees Fahrenheit of the desired
temperature.
[0044] The present invention provides a device for eliminating air
stratification, eliminating air pockets, minimizing inconsistent
temperature, and increasing interior air turns within a facility.
In another embodiment, the present invention provides a device for
minimizing air stratification, minimizing air pockets, minimizing
inconsistent temperature, and increasing interior air turns within
a facility.
[0045] While the present invention is effective at eliminating air
pockets, eliminating air stratification, minimizing inconsistent
temperature, and increasing interior air turns in many facilities,
it is particularly effective at doing so in open ceiling facilities
and 20' clear drop ceiling. Air turns refers to the number of times
air completely rotates or turns over within a facility. Facilities
where a consistent temperature is desired or necessary, such as
industrial buildings, distribution centers, retail operations, food
storage facilities, and pharmaceutical storage facilities will
benefit greatly from the present invention.
[0046] One aspect of the present invention involves a device for
eliminating air stratification, minimizing inconsistent
temperature, and increasing interior air turns within a facility,
wherein a device that includes at least one entrance, at least one
air transfer component--a fan, air induction ports, directional
vanes, and at least three exit zones that incorporate lattices or
louvers.
[0047] Referring now to the drawings in general, the illustrations
are for the purpose of describing a preferred embodiment of the
invention and are not intended to limit the invention thereto.
[0048] FIG. 1 shows a perspective view of one embodiment of the
present invention, illustrating a device that includes a housing
100, at least one air transfer component (a fan) 101, at least one
entrance 103, directional vanes, and at least three exit zones 105,
107, and 109 that incorporate lattices or louvers. The air first
passes over the blades of the fan 101, over directional vanes, and
then exits through the exit zones 105, 107, and 109 and over
lattices or louvers.
[0049] FIG. 2 shows a side view of one embodiment of the present
invention, illustrating a device that includes a housing 100, at
least one air transfer component (a fan), at least one entrance
103, directional vanes, and at least three exit zones 105, 107, and
109 that incorporate lattices or louvers. The air first passes over
the blades of the fan, over directional vanes, and then exits
through the exit zones 105, 107, and 109 and over lattices or
louvers.
[0050] In one embodiment, the device of the present invention
includes at least three exit zones. By including at least three
exit zones in the device, the mixing of air within the volume of
air to be managed is maximized. Air flows out of the device from
three exit zones, which allows for the air to be mixed in many more
different directions than in a device containing only one exit
zone. Preferably, the three exit zones provide for air to flow
substantially horizontally out of the device. This minimizes or
eliminates air pockets that develop when only one exit zone is
used. FIG. 3, particularly the bottom right corner and upper two
corners, illustrates how air pockets form when only one exit zone
is utilized in a device. On the other hand, FIG. 4 illustrates how
air pockets are minimized or eliminated when three exit zones are
utilized in the device.
[0051] The uniform lattice in the exit zones is made of rectangles.
In another embodiment, the uniform lattice is made of circles. In
yet another embodiment, the uniform lattice is made of pentagons.
In a further embodiment, the uniform lattice is made of hexagons,
or a honey combed lattice. In another embodiment, the uniform
lattice is made of heptagons. In yet another embodiment, the
uniform lattice is made of octagons. Alternatively, the lattice is
made of unequally spaced pockets. In one embodiment, the lattice is
angled. In yet another embodiment, the lattice is tapered. In
another embodiment, the lattice is finished with a material such as
epoxy to reduce friction and dust build up. The lattice is not a
filter, but rather directs air flow. In another embodiment, the
lattice is located in the entrance zone of the device.
[0052] In another embodiment, the device contains an air induction
port. The air induction port aids air flow into the device and
produces a more cohesive air flow exiting the device by providing
surfaces for air to travel along as the air enters the device.
[0053] FIG. 5 is a perspective view of one embodiment of the
present invention including a housing 100, air induction ports 301,
lattices 303, and a nozzle 305. The air induction ports draw air
from outside of the unit to mix with the fan driven air. The air
induction ports are in front of the fan blades. The air first
passes over the blades of the fan, through the nozzle, through the
air induction ports zone, over directional vanes, and then exits
through the lattices. Preferably, the nozzle is constructed out of
sheet metal. Notably, the nozzle increases the speed of air through
the unit. In one embodiment, the nozzle increases the speed of air
through the unit by about 10%. In another embodiment, multiple
nozzles are utilized.
[0054] In another embodiment, at least one exit zone to the device
includes at least one lattice for directing air through at least
one of the at least three exit zones of the device.
[0055] FIG. 6 shows a perspective view of one embodiment of the
present invention, illustrating an air transfer component 117, an
entrance to the device including a lattice 119, three exit zones to
the device 121, 123, and 125 including louvers, and an induction
collar with a lattice 311. At least one power source or power
supply is desired to power the at least one air transfer
component.
[0056] FIG. 7 shows a side view of one embodiment of the present
invention, illustrating an air transfer component 117, an entrance
to the device including a lattice 119, three exit zones to the
device 121, 123, and 125 including louvers, and an induction collar
with a lattice 311.
[0057] In one embodiment the air transfer component of the device
is at least one fan. The at least one fan is preferably made of
blades joined together by a hub or any other means. The device
preferably contains a hub keyed to a fan shaft. In one embodiment,
the hub is a typical hub used in the prior art, such as a 10-blade
one-piece cast aluminum hub. However, preferably the hub is the new
6-blade hybrid hub. FIG. 8 shows a typical 10-blade one-piece hub
(left) next to the 6-blade hybrid hub (right). In one embodiment,
the hub is finished with a material such as epoxy to reduce
friction and dust build up. In one embodiment, the fan is 30'', 1/2
hp, and 115/1-12 amps. In another embodiment, the fan is 42'', 3/4
hp, and 115/1-14 amps. The noise level from the 30'' and 42'' fans
does not exceed 12 sones or 64 dba. Alternatively, the fan is a
Dyson fan.
[0058] The blades of the fan preferably operate as both discharge
blades and intake blades. Alternatively, the blades of the fan are
specifically either discharge blades or intake blades. In one
embodiment, the blades are 4-way 20 gauge 360 degree blades. The
blades of the fan are preferably made of galvanized G90 steel
minimum 16 gauge. The blades are preferably epoxy coated. The
blades should be anchored with insert nuts and bolts to eliminate
loosening. The insert nuts and bolts are preferably nylon. In a
preferred embodiment, the insert nuts and bolts are 1/4 inch. In
another embodiment, the insert nuts and bolts and blades of the fan
are finished with a material such as epoxy to reduce friction and
dust build up.
[0059] In one embodiment, the blades of the fan contain tubercles
on the leading edge to increase performance. In a further
embodiment, the tubercles are incorporated into the blade. In
another embodiment, the tubercles are attached to the blade. The
tubercles are preferably made out of the same material as the
blade. Tubercles have the effect of channeling air into smaller
areas of the blade, resulting in a higher speed through the
channels. Furthermore, the tubercles eliminate the tendency of air
to run down the length of the blade's edge and fly off at the tip,
which causes noise, instability, and decreased efficiency. Examples
of blades with tubercles are illustrated in U.S. Pat. No. 8,535,008
for "Turbine and compressor employing tubercle leading edge rotor
design" by Dewar, et al., filed on Oct. 18, 2005 and issued on Sep.
17, 2013, which is incorporated herein by reference in its
entirety. FIG. 9 shows a frontal view of one embodiment of the
present invention where the leading edges of the blades include
tubercles.
[0060] In another embodiment, the blades of the fan are slotted to
increase performance. Specifically, slotted blades help increase
power generation and therefore increase the throw distance of the
device compared to traditional blades. The air throw of prior art
devices is limited to about 50 feet. However, the air throw of the
devices of the present invention is preferably at least about 100
feet. In another embodiment, the air throw of the devices of the
present invention is preferably about 150 feet. In another
embodiment, the air throw of the devices of the present invention
is preferably about 200 feet. However, it should be appreciated
that the air throw of the devices of the present invention are
adjustable anywhere from about 25 feet to about 200 feet. The
present invention includes FIG. 10 shows a frontal view of one
embodiment of the present invention where the leading edges of the
blades include slots.
[0061] In another embodiment, the blades of the fan contain
winglets. In one embodiment, the winglets are incorporated into the
blade. In another embodiment, the winglets are attached to the
blade. The winglets are preferably made out of the same material as
the blade. Examples of blades with winglets are illustrated in U.S.
Pat. No. 6,776,578 for "Winglet-enhanced fan" by Belady, filed on
Nov. 26, 2002 and issued on Aug. 17, 2004, which is incorporated
herein by reference in its entirety.
[0062] In another embodiment, the at least one air transfer
component includes at least two fans configured to counter rotate.
This counter rotation produces a cohesive air flow from at least
one of the at least three exit zones to the device when the fans
are oriented in a parallel configuration. By producing a more
cohesive air flow through the use of counter rotating fans, the
device has a greater throw distance compared to a device with only
one rotating fan. The greater throw distance maximizes the mixing
of air within the volume of air to be managed. FIG. 11 shows an
exploded view of two fans configured to rotate in opposite
directions in order to produce a cohesive air flow exiting the
device. FIG. 3 shows a flow trajectory diagram of a simulation of
flow trajectories coming from a single fan after 30 minutes of the
fan running in a 50'.times.200' building. FIG. 12 shows a flow
trajectory diagram of a simulation of flow trajectories coming from
two fans configured to rotate in opposite directions with a grid
and induction collar after 30 minutes of the fans running in a
50'.times.300' building. As can be seen from FIGS. 3 and 12, the
counter rotating fans produce a much more cohesive flow trajectory
with a greater throw distance than the single fan.
[0063] In one embodiment, the device includes guards. In a further
embodiment, the guards are front guards. Preferably, the front
guards are located near the at least three exit zones to the
device. In another embodiment, the guards are back guards.

within the air volume to be managed. The louvers are adjustable to
the closed position to reduce or eliminate air coming out of the
housing. The louvers also ideally protect the other components of
the device while allowing air to flow into or out of the device.
The louvers also protect living beings and inanimate objects from
the other components of the device. By way of illustration, the
louver sizes of 32''.times.5'', 12''.times.5'', 34''.times.5'',
42''.times.5'', 19''.times.5'', and 46''.times.5'' are suitable for
use in the device. In another embodiment, the louvers are finished
with a material such as epoxy to reduce friction and dust build
up.
[0070] In another embodiment, the at least three exit zones include
lattices and air flows out of the housing through the lattices The
lattices direct air flow out of the housing. The lattices also
protect living beings and inanimate objects from the other
components of the device. In another embodiment, the louvers are
finished with a material such as epoxy to reduce friction and dust
build up.
[0071] In one embodiment, the device includes an air transfer
component and a housing with a substantially open exit zone side
which is at least 90% open, two partially open exit zone sides
which are at least about 50% open, an entrance side, and a top and
bottom. Preferably the substantially open exit zone side and the
two partially open exit zone sides include louvers. The louvers
also preferably extend to cover at least about 50% of the partially
open exit zone sides. The louvers are considered as part of the at
least about 50% that is open in the two partially open exit zone
sides. FIG. 13 shows a perspective view of one embodiment of the
present invention, illustrating a housing having rounded corners
and rounded edges with a top and bottom, an entrance side, a
substantially open exit zone side, two partially open exit zone
sides, a first set of louvers, and a second set of louvers. FIG. 14
shows a side view of one embodiment of the present invention,
illustrating a housing having rounded corners and rounded edges
with a top and bottom, an entrance side, a substantially open exit
zone side, two partially open exit zone sides, a first set of
louvers, and a second set of louvers.
[0072] Having at least about 50% of the partially open exit zone
sides open allows for better mixing of the air within the air
volume to be managed. Air enters the device through the entrance
side and exits the device through the substantially open exit zone
side and two partially open exit zone sides. By having partially
open exit sides, air pockets in the volume of air to be managed are
minimized or eliminated while the greater throw distance from the
substantially open exit zone side is preserved. The louvers of the
substantially open exit zone side and partially open exit zone
sides are adjustable between the open and closed positions, and are
selectively adjustable in partially open positions that modify the
angle of air direction exiting the device to change the air mixing
within the air volume to be managed.
[0073] In one embodiment, the device includes an air transfer
component and a housing with an exit zone. The two side exit zone
side and the open exit zone include lattices. The lattices are
considered as part of the exit zone. FIG. 13 shows a perspective
view of one embodiment of the present invention, illustrating a
housing having rounded corners and rounded edges with a top and
bottom, an entrance side, a substantially open exit zone side, two
partially open exit zone sides, a first set of louvers, and a
second set of louvers. FIG. 14 shows a side view of one embodiment
of the present invention, illustrating a housing having rounded
corners and rounded edges with a top and bottom, an entrance side,
a substantially open exit zone side, two partially open exit zone
sides, a first set of louvers, and a second set of louvers.
[0074] Having at least about 50% of the partially open exit zone
sides open allows for better mixing of the air within the air
volume to be managed. Air enters the device through the entrance
side and exits the device through the substantially open exit zone
side and two partially open exit zone sides. By having partially
open exit sides, air pockets in the volume of air to be managed are
minimized or eliminated while the greater throw distance from the
substantially open exit zone side is preserved.
[0075] In a further embodiment, the device includes at least one
