Abstract: Method for optimizing energy use in vehicles comprising an air-circulation and -recirculation system, the method comprising the steps of measuring a carbon dioxide level of vehicle cabin air, a relative humidity level of cabin air and at least one temperature of at least one window, providing the measured carbon dioxide level, the relative humidity level and the temperature to a processing unit, providing a desired cabin temperature and an indexed optimal carbon dioxide level to the processing unit, calculating deviation of the measured cabin air carbon dioxide level from the indexed optimal carbon dioxide level, calculating optimal cabin air relative humidity level based on the desired cabin temperature, and, based on the calculation, determining the optimal rate at which to provide outside air to the cabin to achieve the calculated optimal cabin air relative humidity level and the indexed optimal carbon dioxide level, determining the recirculation rate required to provide outside air to the cabin at the det

Abstract: An apparatus (10, 110, 210, 310) for the separation and recovery of CO2, from air, by a cyclic adsorption/desorption process using a loose particulate sorbent for gas adsorption. The apparatus has a plurality of adjacent, parallel, spaced-apart layers (24, 124, 224, 324), each having a stiff frame supporting a flexible, gas-permeable fabric enclosure for the sorbent. The gas inlet (14, 114, 214, 314) and outlet (18, 118, 216, 316) of the apparatus are on its axially opposite sides, and each layer (24, 124, 224, 324) extending axially within the apparatus. The recovered CO2 can be either supplied to an enclosed space, recycled to an enclosed space, from which the CO2 had been separated, or vented to the exterior of the latter enclosed space.

Abstract: An apparatus and process for separating and removing CO2 generated by one or more passengers in the air in the interior of a cabin of a vehicle. Provided are: —a first stream of the air from the interior of the cabin to an interior of a container holding a loose particulate sorbent for CO2; —a second stream of air depleted in CO2 from the interior of the container holding the sorbent to an interior of the cabin; —a third stream of the air from exterior of the cabin to the inferior of the container holding the sorbent; and —a fourth stream of air enriched in CO2 from the interior of the container holding the sorbent to an exterior of the cabin.

Abstract: The present invention relates to a device for the reversible adsorption of carbon dioxide from a gas mixture, comprising at least one adsorbent vessel comprising one or a plurality of gas permeable cartridge vessels of an inert and dimensionally stable material, and each cartridge comprising a suitable polymeric particular adsorbent having a primary amino functionality; to an arrangement including the device, and to a method for ad- and desorption of carbon dioxide.
