Description

Technical Field

[0001] Embodiments of this disclosure generally relate to ventilation systems and methods for the internal compartments of vehicles, such as commercial aircraft. Background Technology

[0002] Vehicles (such as commercial aircraft) are used to transport passengers between various locations. Many commercial vehicles (such as aircraft) have high-efficiency particulate air (HEPA) filters in their air conditioning systems that are capable of trapping microorganisms and pathogens. These HEPA filters receive and clean the air leaving the cabin or about to enter it. Frequent cleaning of the HEPA filters and the cabin between flights is one way to ensure the health of passengers and crew on board the aircraft.

[0003] In addition, some passengers may prefer to wear face masks inside the vehicle to reduce the risk of spreading pathogens. However, wearing a face mask during a long-haul flight may be uncomfortable for some passengers. Summary of the Invention

[0004] There is a need for systems and methods for preventing, minimizing or otherwise reducing the risk of transmission of pathogens between passengers on a vehicle during travel (such as between passengers in the interior compartments of an aircraft during flight) without harming passengers.

[0005] In view of this need, certain embodiments of this disclosure provide a system comprising: a seat assembly having a seat duct fluidly connected to one or more air outlets; and an air delivery manifold located below the seat assembly. The air delivery manifold includes a first outlet orifice. The seat duct is fluidly connected to the first outlet orifice. Air is delivered to the one or more air outlets via the air delivery manifold.

[0006] In at least one embodiment, the air delivery manifold is located below the base plate, and the seat assembly is supported on the top surface of the base plate.

[0007] In at least one embodiment, the air supply device receives air. A supply conduit is fluidly connected to the air supply device and the air delivery manifold. Air is drawn from the air supply device into the supply conduit and supplied from the supply conduit to the air delivery manifold.

[0008] In at least one embodiment, one or more fans are arranged within the supply duct.

[0010] In at least one embodiment, the ultraviolet (UV) disinfection subsystem is arranged upstream of or within the air delivery manifold on the supply duct. The UV disinfection subsystem includes one or more UV emitters configured to emit UV light into the air.

[0011] In at least one embodiment, the air delivery manifold further includes a second outlet port. The second outlet port may be open and configured to supply air to the interior compartment. Alternatively, the second outlet port may be blocked.

[0012] In at least one embodiment, at least a portion of the seat conduit extends into at least a portion of one or both of the backrest and headrest of the seat assembly. In at least one example, the headrest includes one or more air outlets.

[0013] In at least one embodiment, one or more air vent grilles are located above the seat assembly. Air is drawn upward from the breathing space associated with the seat assembly into one or more air vent grilles. As an example, one or more air vent grilles are arranged within the ceiling of an interior compartment.

[0014] In at least one embodiment, the seat tube is removably connected to the first outlet port.

[0015] Some embodiments of this disclosure provide a method comprising: fluidly connecting a seat duct of a seat assembly to a first outlet port of an air delivery manifold located below the seat assembly; and delivering air via the air delivery manifold to one or more air outlets of the seat assembly.

[0016] Some embodiments of this disclosure provide a vehicle comprising: an interior compartment including a floor; and a seat assembly supported on a top surface of the floor within the interior compartment. The seat assembly includes a seat duct fluidly connected to one or more air outlets. An air delivery manifold is located below the seat assembly and below the floor.

[0027] The foregoing overview and the following detailed description of certain embodiments will be better understood when read in conjunction with the accompanying drawings. As used herein, elements or steps stated in the singular and preceded by the words "an" or "a kind" should be understood to not necessarily exclude a plural of elements or steps. Furthermore, the reference to "an embodiment" is not intended to be construed as excluding the existence of additional embodiments that also incorporate the described features. Moreover, unless expressly stated to the contrary, embodiments that "comprise" or "have" elements or multiple elements having a particular condition may include additional elements that do not have that condition.

[0028] Some embodiments of this disclosure provide a displacement ventilation system having one or more ducts (such as pipes, air chambers, metal tubes, plastic tubes, manifolds, and / or the like) located below the floor of the interior compartment of the vehicle. Airflow is distributed upward from the ducts into ducts within a seat assembly supported above the floor. The seat assembly also includes one or more air outlets, such as personal ventilation nozzles within the headrest, which direct air toward the breathing zone (e.g., the space within and around the headrest where the passenger breathes). Return air can then be drawn into return air grilles, for example, located in the ceiling, the upper part of the interior compartment, and / or the like. The return air can be processed and recirculated within the interior compartment or expelled from the vehicle. In at least one embodiment, air flows in an upward direction, and a plug-type airflow system may be provided.

[0029] A ventilation system having air outlets in a seat assembly (e.g., each seat assembly within an interior compartment) removes exhaled air, including any pathogens, from the breathing space and draws exhaled air away from the passengers within the interior compartment. Therefore, embodiments of this disclosure provide systems and methods for reducing the spread of pathogens within an interior compartment and for providing effective airflow within the interior compartment.

[0030] As described above, in at least one embodiment, the duct is located below the floor of the interior compartment. The seat assembly's duct connects to the duct from above. In this way, since airflow is guided in an upward direction rather than a downward direction, the duct does not need to be arranged within the sidewalls. Because fewer air ducts can be used, the vehicle's manufacturing process is less labor-intensive, less time-consuming, and less costly. Furthermore, by reducing the amount of ducts within the vehicle (e.g., fewer ducts or no ducts in the sidewall portions), the vehicle is lighter and therefore more fuel-efficient.

[0031] Figure 1 A schematic diagram of an air distribution system 100 for a vehicle 102 according to one embodiment of the present disclosure is shown. The air distribution system 100 includes an air supply device 104 having an air intake device 106 for receiving air 108 (i.e., outside air) from outside the vehicle 102. For example, the air intake device 106 draws outside air into the vehicle 102. In at least one example, the vehicle 102 is an aircraft, and the air supply device 104 includes one or more air conditioners that receive bleed air from one or more engines of the aircraft. As another example, the air supply device 104 includes one or more fans, pumps, and / or the like that draw air 108 into the vehicle 102.

[0032] The air intake device 106 of the air supply device 104 receives air 108 from outside the vehicle 102. The air 108 is then drawn into the supply duct 110. In at least one embodiment, the supply duct 110 includes one or more fans 112 that draw air 108 away from the air intake device and into the air delivery manifold 114.

[0033] In at least one embodiment, an air conditioning subsystem 116 is arranged upstream of and / or within the supply duct 110 of the air delivery manifold 114. The air conditioning subsystem 116 is configured to regulate the air 108 drawn into the supply duct 110. For example, the air conditioning subsystem 116 includes one or more heaters 118 (such as heat exchangers, heating coils, and / or the like) for heating the air 108, one or more filters 120 (such as HEPA filters, adsorbent materials, activated carbon materials, and / or the like) for filtering impurities from the air 108, and / or one or more humidifiers 122 for regulating the humidity of the air 108. Alternatively, the air conditioning subsystem 116 may include a dehumidifier. Optionally, the air conditioning subsystem 116 may include fewer than all of the heaters 118, filters 120, and / or humidifiers 122. Alternatively, the air conditioning subsystem 116 may not be arranged within the supply duct 110.

[0034] In at least one embodiment, the ultraviolet (UV) disinfection subsystem 124 is arranged upstream of and / or within the air delivery manifold 110. The UV disinfection subsystem 124 may be located downstream (or optionally upstream) of the air conditioning subsystem 116. The UV disinfection subsystem 124 includes one or more UV emitters 126 (such as one or more UV lamps, light bulbs, light-emitting diodes (LEDs), and / or the like) configured to emit UV light into the air 108 to disinfect the air 108. In at least one embodiment, the UV emitter 126 is configured to emit UV light in the far-ultraviolet spectrum (such as between 220 and 230 nanometers (nm)). For example, the UV emitter 126 may be configured to emit UV light with a wavelength of 222 nm. In at least one other embodiment, the UV emitter 126 is configured to emit UV light in the UVC spectrum (such as between 230 and 280 nm). For example, the ultraviolet (UV) emitter 126 may be configured to emit UV light with a wavelength of 254 nm. Alternatively, the UV emitter 126 may be configured to emit UV light of different wavelengths, such as those within the far-ultraviolet (UUV) spectrum and the UVC spectrum. Alternatively, the UV emitter 126 may be configured to emit UV light with a wavelength different from that within the UUV or UVC spectrum. Alternatively, the UV disinfection subsystem 124 may not be arranged on and / or within the supply conduit 110.

[0035] The ultraviolet disinfection subsystem 124 is configured to neutralize pathogens in the air traveling through the supply duct 110. The ultraviolet emitter 126 is arranged along the length of the supply duct 110 to ensure that pathogens (such as bacteria, viruses, germs and / or similar substances) in the air passing through the supply duct 110 are neutralized (e.g., killed) before entering the air delivery manifold 124.

[0036] Supply conduit 110 is in fluid communication with air delivery manifold 114. For example, supply conduit 110 may be connected to air delivery manifold 114 via one or more fluid couplings. As another example, delivery manifold 114 is an extension of supply conduit 110. Air delivery manifold 114 extends over a portion of the interior compartment 128 of vehicle 102, such as below and across a row of seat assemblies 130. In at least one embodiment, a plurality of air delivery manifolds 114 are arranged within the interior compartment 128 and in communication with supply conduit 110. For example, each air delivery manifold 114 may be directly coupled to supply conduit 110. As another example, air delivery manifolds 114 may be fluidly coupled together via connecting conduits, and fewer than all air delivery manifolds 114 may be directly coupled to supply conduit 110 (e.g., one air delivery manifold 114 is directly coupled to supply conduit 110, while downstream air delivery manifolds 114 are coupled together via connecting conduits).

[0037] An air delivery manifold 114 is disposed below the floor 132 of the interior compartment 128. A seat assembly 130 is supported above the floor 132, opposite the air delivery manifold 114. As described herein, the seat assembly 130 includes a seat duct 140 configured to fluidly connect to an outlet port 134 of the air delivery manifold 114, which may be disposed below the floor 132.

[0038] The air delivery manifold 114 includes a plurality of outlet ports 134. The outlet ports 134 allow air 108 to exit the air delivery manifold 114.

[0039] Seat assembly 130 includes a ventilation subsystem 136 having one or more air outlets 138 in fluid communication with a seat duct 140 fluidly coupled to an outlet port 134 of an air delivery manifold 114. The seat duct 140 is formed on and / or within at least a portion of the seat assembly 130. For example, the seat duct 140 extends through the backrest and / or headrest of the seat assembly 130. As another example, at least a portion of the seat duct 140 is disposed above (e.g., on a rear surface, side surface, or similar) the backrest, headrest, armrests, seat, and / or similar features of the seat assembly 130.

[0040] As an example, air outlet 138 may be formed in the headrest. In at least one embodiment, air outlet 138 is part of a distribution nozzle formed in the headrest. Air outlet 138 is configured to deliver air 108 to a breathing space near the seat assembly 130. The breathing space is the volume including the headrest and the area where a passenger sitting on the seat assembly inhales and exhales air. As an example, the breathing space is a spherical space extending less than 2 feet from the headrest in all directions.

[0041] In at least one embodiment, one or more return air grilles 147 are disposed within the interior compartment 128. For example, the return air grille 147 is disposed within the ceiling 142 of the interior compartment 128 (which may include the bottom of a luggage rack assembly). The return air grille 147 may include one or more fans that draw air upward into the return air grille 147. Optionally, the fans may be disposed within a duct, pipe, or the like downstream of the return air grille 147. Optionally, the return air grille 147 is disposed within the upper portion of a sidewall. The return air grille 147 is in fluid communication with a return duct 144, which is in fluid communication with an exhaust opening 146 of the vehicle 102. Alternatively, the return duct 144 may be in fluid communication, for example, with a recirculation duct, which is also in fluid communication with an air supply unit 104.

[0042] During operation, the air supply unit 104 draws in outside air 108a into the supply duct 110. The fan 112 operates to draw the outside air 108a into and through the air conditioning subsystem 116. The air conditioning subsystem 116 processes the outside air 108a to provide processed air 108b. For example, a heater 118 can heat the outside air 108a. As another example, a filter 120 can filter out particulate matter and impurities from the outside air 108a. As another example, a humidifier 122 can humidify the outside air 108a.

[0043] The treated air 108b can also be treated by an ultraviolet (UV) disinfection subsystem 124, which may be located downstream (or optionally upstream) of the air conditioning subsystem 116. The UV emitter 126 of the UV disinfection subsystem 124 emits UV light into the air 108 to neutralize pathogens (such as bacteria, germs, viruses, and / or the like).

[0044] The air conditioning subsystem 116 and the ultraviolet disinfection subsystem 124 process the outside air 108a to provide the processed air 108b to the air delivery manifold 114. That is, the air has been processed, for example, by the air conditioning subsystem 116 and / or the ultraviolet disinfection subsystem 124, before being delivered to the seat assembly 130 via the air delivery manifold 114.

[0045] As shown in the figure, the air distribution system 100 includes an air conditioning subsystem 116 and an ultraviolet disinfection subsystem 124 located upstream of the seat assembly 130 within the interior compartment 128. Thus, the seat assembly 130 does not need to include separate air conditioning components such as heaters, filters, humidifiers, ultraviolet emitters, and / or the like. In this way, the seat assembly 130 can provide dry, purified, and clean air to the breathing space without the complexity and cost associated with having separate and distinct air conditioning components and ultraviolet emitters. Alternatively, the seat assembly 130 may include one or more air conditioning components and / or ultraviolet emitters that can be individually controlled.

[0046] Fan 112 directs treated air 108b into air delivery manifold 114 and seat assembly 130. Fan 112 may be arranged throughout supply duct 110. For example, fan 112 may be located upstream and / or downstream of air conditioning subsystem 116 and UV disinfection subsystem 124. In at least one embodiment, one or more fans 112 may also be arranged within air delivery manifold 114. Fan 112 directs airflow into seat assembly 130. Therefore, seat assembly 130 does not need to include a separate fan, which reduces the cost, complexity, and weight of seat assembly 130. The weight of seat assembly 130 is reduced by reducing the number of components (such as air conditioning components, UV emitters, fans, and / or the like) within seat assembly 130. The lighter seat assembly 130 on vehicle 102 results in increased fuel efficiency. Alternatively, seat assembly 130 may include one or more fans.

[0047] Processed air 108b enters the seat duct 140, which is fluidly connected to the outlet port 134 of the air delivery manifold 114. The processed air 108b is then delivered through air outlet 138 to a breathing space associated with the seat assembly 130, such as above or within the headrest, backrest, and / or similar features of the seat assembly 130. A passenger seated in the seat assembly 130 inhales clean, purified, processed air 108b and exhales air 108c into the breathing space. The exhaled air 108c is drawn out of the breathing space (and away from other passengers within the interior compartment 128) by an upward airflow A. The exhaled air 108c is drawn into the return air grille 147 and into the return duct 144. The exhaled air 108c can then be discharged from the vehicle 102 through the exhaust opening 146, or recirculated, for example, through a recirculation duct to the air supply unit 104.

[0048] In at least one embodiment, the interior compartment 128 includes a plurality of seat assemblies 130 having a ventilation subsystem 136 fluidly connected to one or more air delivery manifolds 114, which in turn are fluidly connected to a supply duct 110. In at least one embodiment, all seat assemblies 130 within the interior compartment 128 are fluidly connected to one or more air delivery manifolds 114. In at least one other embodiment, fewer than all seat assemblies 130 within the interior compartment 128 are fluidly connected to one or more air delivery manifolds 114.

[0049] In at least one embodiment, the air delivery manifold 114 includes a plurality of outlet holes 134. Some of these outlet holes 134 are in fluid communication with the seat duct 140 of the seat assembly 130. Other outlet holes 134 may be open and fluidly connected to an air outlet 148 formed in the floor 132, thereby supplying treated air 108b to the interior compartment 128 and generally to the air outlet 138 of the seat assembly 130. In at least one other embodiment, at least some of the outlet holes 134 that are not connected to the seat duct 140 may be blocked to prevent fluid from passing through them. These outlet holes 134 may be blocked to control the air pressure of the treated air 108b delivered to the seat assembly 130.

[0050] As described herein, in at least one embodiment, system 100 includes a seat assembly 130 having a seat duct 140 fluidly coupled to one or more air outlets 138. An air delivery manifold 114 is located below the seat assembly 130. As an example, the air delivery manifold 114 is not part of the seat assembly 130. The air delivery manifold 114 includes an outlet orifice 134. The seat duct 140 is fluidly coupled to the outlet orifice 134. Air (such as treated air 108b) is delivered via the air delivery manifold 114 to one or more air outlets 138.

[0051] In at least one embodiment, the air delivery manifold 114 is located below the base plate 132. Alternatively, the air delivery manifold 114 may be embedded within the base plate 132, or have at least a portion located above the base plate 132. The seat assembly 130 is supported on the top surface 133 of the base plate 132.

[0052] Figure 2 A schematic diagram of a seat duct 140, separate from the outlet port 134a of the air delivery manifold 114, is shown according to one embodiment of this disclosure. See also Figure 1 and Figure 2 The seat assembly 130 includes a seat conduit 140 configured to be fluidly connected to an outlet port 134a. For example, the seat conduit 140 may include a plug 141 configured to mate with a complementary socket 135 of the outlet port 134a. Alternatively, the seat conduit 140 may include a socket, while the outlet port 134a may include a plug. In this manner, the seat conduit 140 can be removably coupled to the outlet port 134a via a plug and socket connection. In at least one other embodiment, the seat conduit 140 may be removably coupled to the outlet port 134a via one or more latches, threaded connections, one or more snaps, one or more latches, and / or the like. By removably coupling the seat conduit 140 to the outlet port 134a, the seat assembly 130 can be selectively removed and replaced, for example, when the seat assembly 130a requires maintenance. In at least one other embodiment, the seat conduit 140 may be coupled to the outlet port 134a via one or more fasteners, such as screws, bolts, or the like. In at least one other embodiment, the seat conduit 140 may be permanently fixed to the outlet port 134a, for example by welding, bonding or similar means.

[0053] As shown, the outlet port 134b can be open, thereby providing treated air 108b to the interior compartment 128, such as to the passageway between the seat assemblies 130. The outlet port 134c can be closed, for example, via a plug 150 removably coupled to the outlet port 134c.

[0054] Each seat assembly 130 within the interior compartment 128 is fluidly connected to a corresponding outlet port 134 via a corresponding seat conduit 140. That is, each seat assembly 130 may include a seat conduit 140 fluidly connected to a corresponding outlet port 134. Optionally, multiple seat assemblies 130 may be fluidly connected to the outlet port 134 via a common seat conduit.

[0055] Figure 3 A schematic diagram of a seating system 160 according to one embodiment of the present disclosure is shown. The seating system 160 includes a plurality of seat assemblies 130a, 130b, and 130c. The seating system 160 may include more or fewer seat assemblies than those shown.

[0056] Seating system 160 includes a seat duct 140 shared by seat assemblies 130a, 130b, and 130c. For example, seat duct 140 includes an air inlet 162 configured to fluidly connect to an outlet port 134 of an air delivery manifold 114. Figure 1 and Figure 2 (As shown in the diagram). Air inlet 162 is fluidly connected to branch duct 164, which has air outlet 138 fluidly connected to the respective seat assemblies 130a, 130b and 130c (in the diagram). Figure 1 The conveying pipes 166a, 166b and 166c are shown in the figure.

[0057] Figure 4 A schematic diagram of an aircraft 200 according to one embodiment of the present disclosure is shown. The aircraft 200 is about... Figure 1 Example of vehicle 102 shown and described. Air supply unit 250 ( Figure 1 The example of the air supply device 114 shown is fluidly connected to the supply pipe 252. Figure 1 Example of supply pipe 110 shown), which is fluidly connected to air delivery manifold 214. Figure 1 (Example of air supply manifold 114 shown). Flow control devices (such as, but not limited to, valves) may be fluidly connected to supply line 252 and positioned between air supply unit 250 and air supply outlet 254. In the example shown, air supply unit 250 is shown connected to a first engine 258 and a second engine 260, for example, to the right engine and the left engine, respectively. Air supply unit 250 may be connected to a single engine or more than two engines. Air supply unit 250 may also be connected to a compressor (not shown) to exhaust air from the fuselage without fluid communication with engines 258 and 260.

[0058] As shown, treated air 108b is supplied to seat assembly 130 and optionally to aisle 139 and / or other areas within interior compartment 228. Exhaled air 108c can be drawn into, for example, a return air grille 240 that may be arranged within ceiling 242.

[0059] Figure 5 A perspective rear view of a seat assembly 130 fluidly connected to an air delivery manifold 114 according to one embodiment of the present disclosure is shown. The seat assembly 130 includes a base 300, which may include support legs 302. The base 300 supports a seat plate 304 having a seat cushion 306. A backrest 308 extends upward from the rear of the seat plate 304. A headrest 310 is located on the upper portion of the backrest 308.

[0060] As shown in the figure, the seat duct 140 is fixed inside and / or fixed to the rear portion 312 of the backrest 308. The seat duct 140 extends downward from the backrest 308, passes through the opening 314 of the base plate 132 and is in fluid communication with the outlet port 134 of the air delivery manifold 114.

[0061] In at least one embodiment, the seat duct 140 includes a main section 320 directly coupled to an outlet port 134. The main section 320 receives processed air 108b from the air delivery manifold 114. The main section 320 is fluidly connected to a branch section 322, such as one that may be arranged inside the backrest 308. The branch section 322 is in turn fluidly connected to a left section 324 and a right section 326. The left section 324 is fluidly connected to an air outlet 138 (such as a dispensing nozzle) of the left wing 330 of the headrest 310. The right section 324 is fluidly connected to an air outlet 138 of the right wing 332 of the headrest 310. Thus, the air outlet 138 delivers processed air 108b to each side of the breathing space 340 of the headrest 310.

[0062] In at least one embodiment, the breathing space 340 may not extend beyond the lateral or rear portion of the headrest 310. Furthermore, the breathing space 340 may not extend forward beyond the rear surface of the seat assembly (not shown) located directly in front of the seat assembly 130. Therefore, the breathing space 340 can be limited to a spatial volume associated with the seating volume 341 of the seat assembly 130 (i.e., the space volume where the passenger is seated). An upward airflow of processed air 108b delivered to the breathing space 340 delivers fresh processed air 108b to the breathing space 340, and exhaled air is drawn upward into the return air grille 147 (as per [reference to...]). Figure 1 (as shown and described).

[0063] The seat duct 140 may be constructed in a manner different from that shown. For example, the seat duct 140 may not have branch sections. For example, the seat duct 140 may be fluidly connected to the air outlet 138 on one side of the breathing space 340, above the breathing space, and / or in a similar manner. In at least one other embodiment, the seat duct 140 may branch to another air outlet 138, for example, located above or below the breathing space 340.

[0064] In at least one embodiment, the seat assembly 130 may not include wings 330 and 332. Instead, air outlet 138 may be arranged on and / or within the front and / or rear portion of the headrest 310. In at least one embodiment, air outlet 138 may be arranged in other portions of the seat assembly 130 besides or replacing the headrest 310.
