摘要： 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.

摘要： An electric temperature control system for unpressurized aircraft and methods for operating are disclosed. The electric temperature control system may be electrically powered and used on all-electric aircraft or hybrid aircraft. The electric temperature control system may comprise a vapor cycle cooling system for cooling air and an electric heater for heating air. The electric heater may be a PTC electric heater with individually-controllable heating elements. Various input devices may be disposed in the aircraft allowing an operator to set a compartment temperature, an air source, and a fan speed. A controller controls operations of the electric temperature control system based on feedback received from a plurality of feedback devices and the operator inputs.

摘要： The present disclosure provides for air management systems, assemblies and methods. More particularly, the present disclosure provides for air management systems, assemblies and methods (e.g., for aircraft or the like), with the air management systems/assemblies having negative ion technology for improved air quality. The present disclosure provides improved air conditioning/management systems having features to handle the poisonous/toxic chemicals/gases (e.g., carbon monoxide), climate relevant gases (e.g., methane), and/or harmful bacteria/viruses (e.g., SARS-CoV-2), and to improve the air quality inside the aircraft through the disclosed air conditioning/management systems.

摘要： An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer wall of filter media having a shape that defines an interior volume of the filter. The apparatus further includes an ultraviolet light disposed on an end plate, configured to be mounted with the ultraviolet light positioned in the interior volume of the filter and the end plate against an open end of the filter. The ultraviolet light is configured to emit ultraviolet radiation substantially at between 222 nm and 265 nm for irradiating air flow through the filter into the air circulation system.
