Abstract:
An aircraft air conditioner in which air extracted from an engine that is fed through a main air flow path into an aircraft cabin is cooled by a cooling device, comprising:an outflow air flow path for outflow of air in the cabin; an auxiliary air flow path for feeding air into the cabin; a plurality of adsorption sections respectively constituted by an adsorption agent that adsorbs molecules contained in the air and that releases the adsorbed molecules by being raised in temperature to more than the temperature thereof on adsorption; an air flow path changeover mechanism; and a controller that controls the air flow path changeover mechanism, wherein each of the adsorption sections is adapted to being changed over between a condition in which it is connected to an auxiliary air flow path in which air of higher temperature than the air within the cabin flows and a condition in which it is connected to the outflow air flow path by means of the air flow path changeover mechanism, each of the adsorption sections is changed over between the condition connected to the auxiliary air flow path and the condition connected to the outflow air flow path by controlling the air flow path changeover mechanism by the controller, and an air flow path of the air conditioner is adapted to feed the air flowing out from said cabin through said outflow air flow path to the cabin again after passing through said adsorption sections.
