PURPOSE: To prevent any increase in an amount of bleed air by passing the air in a cabin through a permeation film type CO2 separator, exhausting the air which is high in CO2 density out of an aircraft and supplementing the exhaust air amount from a jet engine compressor in the air conditioner of a jet aircraft.
CONSTITUTION: The air in a cabin 6 is passed through a separator 11 having a permeation film 13 which permeates carbon dioxide selectively. Then, the air which has increased density of carbon dioxide through the permeation film 13 is exhausted out of the aircraft through an exhaust port 10, the air which has become low in the density of carbon dioxide is circulated inside the cabin through an air circulation duct 8, and then the amount of air equivalent to the amount of exhaust air is bled through the compressor of a jet engine to be supplied to the cabin. With this constitution, it is possible to attempt the decrease of the carbon dioxide density without increasing the amount of bleed air from the compressor.
