Systems and methods provide airflow to a flight deck from a passenger entry area. The system includes a fan mounted within a door separating a flight deck from a passenger entry area. The fan is configured to direct airflow from the passenger entry area into the flight deck. The fan having a shield positioned adjacent to the passenger entry area that is configured to conceal the fan.

An Environmental Control Systems (ECS) for an aerospace vehicle comprises an air supply airflow path inputting, monitoring, and conditioning air from external to the vehicle, and a recirculation airflow path inputting, monitoring, filtering, and moving air from one portion of the interior of the vehicle to another portion. The air supply airflow can include a dynamically controlled VOC/ozone converter, which can be operated when the aerospace vehicle is on the ground. The recirculation airflow path can include a dynamically controlled regenerative gas contaminant filter and/or VOC/CO2 removal device. The filter/adsorption media of the controlled regenerative gas contaminant filter and/or VOC/CO2 removal device can be regenerated by suppling hot air or a vacuum, and gaseous contaminants can be broken down for removal from the regenerative gas contaminant filter by controlling UV irradiation. The controller can alert a flight crew if air quality falls outside predetermined or programmable parameters.

Methods, apparatus, systems, and articles of manufactures for aircraft cabin temperature control using temperature data from mobile electronic devices are described herein. An example mobile electronic device described herein includes a transceiver to receive a climate characteristic value measured by a personal mobile electronic device in a cabin of an aircraft and a cabin air manager to calculate an updated climate characteristic setting for an environmental control system (ECS) of the aircraft based on a current climate characteristic setting of the ECS and the climate characteristic value.

A method for air conditioning of an aircraft includes the steps of: (A) obtaining a fresh air for ventilation; (B) exhausting an air from a cabin; (C) obtaining a purified air for recirculation, from a part of the air exhausted in the step (B); (D) obtaining an air for ventilation; (E) supplying the air for ventilation to the cabin; and (F) irradiating an ultraviolet ray emitted from a UV-LED to the fresh air for ventilation, an air for recirculation, the purified air for recirculation, and/or the air for ventilation.

An aircraft air conditioning system includes a lower cooling zone and an upper cooling zone. The lower cooling zone includes a lower recirculation heat exchanger configured to receive cabin air from a cabin and convert the cabin air into lower cooled recirculated cabin air. The upper cooling zone includes an upper recirculation heat exchange configured to receive the cabin air from the cabin and convert the cabin air into upper cooled recirculated cabin air. A power system selectively delivers power to the lower cooling zone and the upper cooling zone. A controller is in signal communication with the power system. The controller determines a target temperature of the cabin and invokes a recirculation ground maintenance mode that commands the power system to deliver power to one or both of the lower cooling zone and the upper cooling zone so that a temperature of the cabin reaches the target temperature.

An air ionizer is integrated into aircraft executive and VIP suites. The integrated air ionizers provide personalized fresh air and ionization to the passenger's comfort. Air ionizers integrated in aircraft suites is effective, provides increased ion concentration, and reduces malodor, improve cabin air quality, and increase confidence to fly. The air ionizer provides IFE controlled ionization level.

Disclosed is a method and a device for thermally controlling a plurality of cabins of a vehicle from a mixing chamber supplied with air from at least one air supply device of which at least the temperature is controlled, each cabin being supplied with air by a supply conduit specific to this cabin. At least one cabin is supplied with air at a temperature adjusted by at least one individual exchanger associated with the supply conduit specific to this cabin, in which a second circuit is supplied with a heat transfer fluid from at least one heat transfer fluid thermal regulation loop of the vehicle. Also disclosed is a vehicle provided with at least one thermal control device.

A passenger service system includes a seat, a first sensor associated with the seat that senses a position of the seat and generates a first signal, a second sensor associated with the seat that senses the presence of a passenger in the seat and generates a second signal, a first light source disposed at a predetermined location with respect to the seat, where the first light source generates light, a third sensor associated with the first light source that senses at least a position of at least one hand of the passenger and generate a third signal, and a controller that receives the first signal, a first light signal that controls at least one parameter associated with the light including at least one of an intensity, a color, a projected pattern, projected pattern location, or a width.

A method for controlling an aircraft air conditioning system includes the steps of detecting an operating state of an air conditioning unit of the aircraft air conditioning system and controlling the temperature of a process air mass flow supplied to the air conditioning unit in dependence on the operating state of the air conditioning unit.

A vehicle includes a first area conditioned by a first medium, a second area conditioned by a second medium, and an air management system. The air management system includes a source of third medium, an environmental control system fluidly coupled to the source of third medium and to the second area, and a closed loop vapor compression system having a refrigeration medium circulating therein. The vapor compression system is fluidly coupled to the first area, the second area, and the source of third medium. During normal operation, both a first flow of the third medium conditioned within the environmental control system and a second flow of the third medium are provided to the second area.
