Certain embodiments of the present disclosure provide a ventilation system for an interior space (eg, an internal cabin of a transporter such as a commercial aircraft). The ventilation system includes one or more distribution nozzles associated with the seat, and a recirculated air grill associated with the seat. In at least one embodiment, each seat in the internal cabin has one or more distribution nozzles and a return air grill associated with the seat. For example, one or more distribution nozzles are located above the seat and the reflux air grill is mounted below and / or above a portion of the seat. In this way, the airflow is directed downward and perpendicular to the seat. By providing a downward airflow to the seat, fresh and clean air is provided to the passengers in the seat, along with the air (such as from passengers seated near the seat). Introduction to the respiratory zone is also minimized or otherwise reduced. Air is received by the reflux air grill and directed away from passengers and other passengers in the internal cabin. In this way, embodiments of the present disclosure are configured to provide plug flow (also referred to as unidirectional or piston flow) within the internal cabin, or performance approaching plug flow, which is within the internal cabin. Minimize or otherwise reduce the potential for transmission of pathogens among passengers.

Certain embodiments of the present disclosure provide a ventilation system that provides airflow above the passengers. The airflow travels vertically downward to the recirculated air grill associated with the seat in the internal cabin. The downwardly vertical airflow provides a clean air path to the passengers and ventilates the exhaled air from the passengers away from other passengers. The ventilation systems and methods described herein reduce the spread of pathogens within the internal cabin of the transporter.

FIG. 1 is a schematic diagram of a ventilation system 100 for an internal cabin 104 of a transporter 104 according to an embodiment of the present disclosure. In at least one embodiment, transporter 104 is a commercial aircraft. The internal cabin 104 is an example of an internal space. Other examples of interior spaces include rooms in buildings.

The ventilation system 100 includes one or more distribution nozzles 106 associated with a seat 108 in the internal cabin 104. For example, each seat 108 is assigned or otherwise distributed by its own distribution nozzle 106. Further, the reflux air grill 110 is associated with the seat 108. For example, each seat 108 is assigned or otherwise serviced by its own recirculating air grill 110.

In at least one embodiment, the one or more distribution nozzles 106 are above the seat 108 and the recirculated air grill 110 is fixed below the seat 108 and / or above a portion of the seat 108 (eg, mounted). ing). In at least one embodiment, each seat 108 in the interior space 104 is associated with one or more distribution nozzles 106 and a reflux air grill 110. In at least one other embodiment, less than all of the seats 108 in the internal cabin 104 are associated with one or more distribution nozzles 106 and recirculated air grills 110.

In at least one embodiment, one or more distribution nozzles 106 include at least two distribution nozzles 106. For example, five or more distribution nozzles 106 may be associated with seat 108. Increasing the number of distribution nozzles 106 in the internal cabin 102 reduces the flow rate of the airflow 112 exiting the distribution nozzle 106, but distributes more evenly. Optionally, the single distribution nozzle 106 is associated with the seat 108.

In at least one embodiment, the distribution nozzle 106 is configured to provide an air curtain that directs the airflow towards the recirculated air grill 110. The air curtain may be directed in front of, sideways, and / or behind the passengers in the seat 108.

The distribution nozzle 106 is located above the seat 108 and the recirculated air grill 110 is located below the cushion 114 of the seat 108 on which the passenger sits. Therefore, the airflow 112 is directed downward from the distribution nozzle 106 toward the recirculated air grill 110. Since the airflow 112 is directed downward and vertically from the distribution nozzle 106 to the recirculating air grill 110, the airflow 112 reduces turbulence or mixing. Therefore, the airflow 112 can smoothly flow around the portion of the seat 108 and obstacles such as passengers sitting in the seat 108. In this way, clean and fresh air is provided to the passengers in seat 108. Passengers breathe in fresh, clean air and then expel air directed downward by the downward airflow 112 into the recirculated air grill 110. Therefore, contaminants, pathogens and the like are less likely to be mixed into the air in the internal cabin 104, but are instead attracted into the recirculated air grill 110. Optionally, the airflow 112 may be turbulent or slightly turbulent.

In at least one embodiment, the airflow 112 is directed overhead and / or into and / or towards the passenger's breathing zone. Thus, the airflow 112 takes up the released bioaerosol (eg, from speaking, sneezing, coughing, breathing, etc.) and then the bioaerosol is directed to the reflux air grill 110.

The distribution nozzle 106 is fluidly coupled to the air distribution subsystem 116 of the transporter 104 through one or more air passages 118 such as one or more ducts, one or more tubes, and one or more plenums. The recirculated air grill 110 passes through one or more air passages 124 such as one or more ducts, one or more tubes, one or more plenums, and one or more outflow valves 120 and / or (eg, one or more air filters, etc. It is fluid connected to an air filtration subsystem 122 (which may include a fan, etc.). The air filtration subsystem 122 is fluid connected to the air distribution subsystem 116 through one or more air passages 126 such as one or more ducts, one or more tubes, and one or more plenums. Optionally, the ventilation system 100 may not include the air filtration subsystem 122. Alternatively, the recirculated air grill 110 may be connected only to the outflow valve 120. In some options, the ventilation system 100 may not include the outflow valve 120. Alternatively, the reflux air grill 110 may be coupled only to the air filtration subsystem 122.

In operation, the air distribution subsystem 116 provides fresh, clean air to one or more distribution nozzles 106. For example, the air distribution subsystem 116 provides the distribution nozzle 106 with fresh, clean air drawn from the outside of the transporter 104. As a further example of a commercial aircraft, air is separated from the engine and is received, for example, by an air conditioning subsystem that may be below or close to the wing box. The air conditioning subsystem receives high pressure, high temperature air from the engine, regulates the air, and then outputs the air as cold, dry, low pressure air. The air is then supplied to the bulkheads in the pressurized area of the aircraft. The air can then be mixed in the mixing bay, which also accepts purified and purified air from the air filtration subsystem 122. The mixed air can then be supplied by the air distribution subsystem 116 as fresh and clean air.

The distribution nozzle 106 receives clean and fresh air from the air distribution subsystem 116 and directs the layered airflow 112 from above the passengers in the seat 108 downward and vertically toward the recirculated air grill 110 by arrow A. Output in the direction (ie, from above the passenger to below the passenger). Alternatively, the airflow 112 may be turbulent or slightly turbulent. Therefore, passengers in seat 108 are provided with fresh, clean air. The air exhaled by the passengers in the seat 108 is drawn downward by the airflow 112 into the recirculated air grill 110 and / or on the surface (eg, floor, armrests, passenger clothing, etc.) and later cleaned. Can be. Therefore, exhaled air from passengers, including contaminants, pathogens, etc., is not mixed into the air in the internal cabin 104, but is instead drawn into the recirculated air grill 110. The airflow received by the recirculated air grill 110 is then supplied to the outflow valve 120, where the outflow valve is exhausted from the transport body 104 and / or into the air filtration subsystem 122, where the air filtration subsystem is a filter (eg, HEPA). Includes a filter), which removes contaminants, pathogens, etc. from the air. The purified air is then supplied through the air passage 126 to the air distribution subsystem 116.

As described herein, the ventilation system 100 includes one or more distribution nozzles 106 associated with a seat 108 in an interior space, such as an internal cabin 104. The recirculated air grill 110 is also associated with the seat 108. The airflow 112 is directed from one or more distribution nozzles 106 toward the recirculated air grill 110 and into the recirculated air grill.

Further, in at least one embodiment, the transporter 104 comprises an internal cabin 104. The plurality of seats 108 are in the internal cabin 104. The ventilation system 100 includes one or more distribution nozzles 106 and a perfusion air grill 110 associated with each of the plurality of seats 108.
