A system and method include a seat assembly including a seat duct fluidly coupled to one or more air outlets. An air delivery manifold is underneath the seat assembly. The air delivery manifold includes a first outlet port. The seat duct is fluidly coupled to the first outlet port. Air is delivered to the one or more air outlets via the air delivery manifold.

Ventilation systems and methods for internal cabins of vehicles

A headrest ventilation assembly is configured to secure to a headrest of a seat assembly, and includes an air conduit including one or more air inlets and one or more air outlets, and an air filter disposed within the air conduit between the one or more air inlets and the one or more air outlets. The air filter is configured to remove contaminants from the air that is drawn into the air conduit before being delivered out of the one or more air outlets. The assembly can also include a fan disposed on or within the air conduit. The fan is configured to draw the air into the one or more air inlets and provide airflow to deliver the air out of the one or more air outlets. The assembly can also include one or more ultraviolet (UV) light emitters disposed on or within the air conduit. The UV light emitter(s) are configured to emit UV light into the air to sanitize the air before the air is delivered out of the one or more air outlets.

Headrest ventilation systems and methods for seating assemblies

A method for evaluating an air purification system. The method includes generating, with an air flow generator, a flow of air through a test filter so that an upstream air flow exists an upstream side of the test filter and a downstream air flow exists on a downstream side of the test filter. A multiple contaminant mixture is injected, with a fluid injector, into the upstream air flow. Downstream concentrations for each contaminant of the multiple contaminant mixture in the downstream air flow are measured with a contaminant measurement device. Test filter breakthrough curves for each contaminant of the multiple contaminant mixture in the downstream air flow are generated based on the downstream concentrations for each contaminant of the multiple contaminant mixture.

System and methods for evaluating an air purification system

A method for providing purified air to an occupant of a seat in a mask lacking corporeal features that is generated by an apparatus. The apparatus includes a contaminant conditioning system that delivers purified air to a first and a second laminar flow generator. Each laminar flow generator produces a respective laminar flow that combines to form and fill a breathing space with purified air that envelopes an inhalation sphere of the occupant and inhibits air other than the purified air from entering the breathing space.

Personal ventilation in an aircraft environment

Systems and methods for providing airflow in an aerospace vehicle are disclosed. A system in accordance with one embodiment includes an aerospace vehicle having an interior volume with a first portion and a second portion. The system can further include an external air supply device positioned to provide supply air to the interior volume at a variable supply flow rate and a recirculation fan configured to move air positioned within the interior volume between the first portion of the interior volume and the second portion of the interior volume. The system can still further include a controller operably coupled to the recirculation fan and configured to vary a rotation speed of the recirculation fan. Variations in the rotation speed of the recirculation fan can be associated with variations in a recirculation flow rate. In selected embodiments, the system can include sensors and/or data link devices operably coupled to the controller.
