Patent ID: 8795041

Claim:
A conditioned air supply system for an aircraft, comprising: an oxygen-enriched air generator that generates oxygen-enriched air as conditioned air in said aircraft; a measurement device that measures a pressure inside a cabin of said aircraft; a storage device that stores a preset relationship between a pressure inside said cabin and a target partial pressure; said relationship being set so that said target partial pressure exceeds a value obtained by multiplying the pressure inside said cabin by an oxygen concentration ratio in the air on the earth's surface and is equal to or less than an oxygen partial pressure in the air on the earth's surface; a target partial pressure determination device that finds said target partial pressure on the basis of said relationship and the measured pressure inside said cabin; a control device that controls said oxygen-enriched air generator so that an oxygen partial pressure of the generated conditioned air becomes said target partial pressure; a piping having a plurality of air blow-off ports connected to said oxygen-enriched air generator; said air blow-off ports being disposed in locations in which said conditioned air can be blown so as to reach respective face disposition regions of passengers in a plurality of seat locations inside said cabin; and a mixing chamber that introduces a flow of air having oxygen concentration lower than the oxygen concentration of the conditioned air to areas of the cabin other than the face disposition regions of the cabin where the conditioned air is blown.
