HVAC air distribution device to promote temperature stratification
An HVAC air distribution device to promote temperature stratification within a larger volume. The device comprised of a front side coupled to a back side defining a cavity for directing a flow of air. The front side comprised of a pliable material and configured for the distribution of the flow of air within the channel. Accordingly, the front side comprises an air permeable portion to release flow from the channel to provide a low velocity of uniform air flow across a length of the device. This low velocity uniform air flow encourages temperature stratification within a distinct area of the larger volume to increase comfort of an occupant and promote efficiency of HVAC systems.
1. A device to direct a flow of conditioned air within a larger volume to establish a distinct zone of conditioned air within the larger volume, the device comprising:
a backside, the backside generally planar and configured for a coupling to a vertical structure defining the larger volume; and
a front side, the front side coupled to the backside to generally define a channel for capturing the flow of conditioned air, the front side comprised of a pliable material being comprised of woven fabric material configured with an air permeable portion and an air impermeable portion, wherein the air permeable portion releases the captured flow at a uniform velocity across an entire length of the air permeable portion, wherein the air permeable portion is defined by pores between threads of the woven fabric allowing for the releasing of a discrete amount of air jets from the channel into the larger volume, wherein the discrete amount of air jets selectively provides conditioned air to the distinct zone, wherein the distinct zone is a smaller volume within the larger volume.
2. The device as in claim 1 , wherein the front side includes a plurality of pores, the pores each have a size, the size of each of the plurality of pores increasing in proportion to a distance from an entrance of airflow within the device to provide a uniform flow across an entire length of the air permeable portion.
3. The device as in claim 2 , wherein each pore of the plurality of pores is spaced a distance from each other, the distance between each pore decreasing in proportion to a distance from an entrance of airflow, wherein a number of pores increases as the distance from the entrance increases to provide a uniform flow across an entire length of the air permeable portion.
4. The device as in claim 1 , wherein the front side and back side define an interior diameter of the channel, the interior diameter of the channel decreasing in proportion to a distance from an entrance of airflow, wherein the channel narrows as the distance from the entrance increases.
5. The device as in claim 1 , wherein the device is installed into an existing HVAC system of the larger volume, wherein the device is coupled to an aperture within a wall of the larger volume aligned with an existing duct.
6. A device to direct a flow of conditioned air within a larger volume to establish a distinct zone of conditioned air within the larger volume, the device comprising:
a backside, the backside comprising a rigid planar material and configured for a coupling to a vertical structure defining the larger volume;
a front side, the front side having an air permeable portion and an air impermeable portion, and coupled to the backside to generally define a channel for capturing the flow of conditioned air, the front side comprised of a pliable material comprised of woven fabric material, wherein the air permeable portion is defined by pores between threads of the woven fabric allowing for the releasing of a discrete amount of air jets from the channel into the larger volume across an entire length of the air permeable portion;
a first end, the first end being a seal of the front side and backside adjacent to an entrance, wherein air flow is restricted from exiting; and
a second end, the second end opposite the first end and a distance from the first end to the second end defining a length of the device, the second end being a seal of the front side and backside, wherein air flow is restricted from exiting.
7. The device as in claim 6 , wherein the front side includes a plurality of pores, with each pore of the plurality of pores having a size, the size of each of the plurality of pores increasing in proportion to a distance from the entrance of airflow within the device to provide the uniform flow across an entire length of the air permeable portion.
8. The device as in claim 6 , wherein the front side includes a plurality of pores, with each pore of the plurality of pores spaced a distance from each other, the distance between each pore decreasing in proportion to a distance from the entrance of airflow, wherein a number of pores increases as the distance from the entrance increases to provide the uniform flow across an entire length of the air permeable portion.
9. The device as in claim 6 , wherein the front side and back side define an interior diameter of the channel, the interior diameter of the channel decreasing along the length of the device, from the first end to the second end, wherein the channel narrows from the first end to the second end.
10. The device as in claim 6 , wherein the device is installed into an existing HVAC system of the larger volume, wherein the device is coupled to an aperture within a wall of the larger volume aligned with an existing duct.
11. The device as in claim 6 , wherein a flow of conditioned air is captured in the channel with a first direction parallel to the front side, and wherein the flow of conditioned air changes direction and reduces in velocity when being released as the discrete amount of air jets exiting through the air permeable portion and wherein the discrete amount of air jets is directed normal to the front side and the velocity of any of the individual jets is lower than the velocity of the flow of conditioned air captured in the channel.
