PURPOSE:To obtain the comfortable air conditioning by detecting the oxygen concentration in the car compartment and controlling the oxygen concentration in the car compartment to a prescribed value on the basis of the result of the detection, in an air conditioner for feeding the air containing the enriched oxygen which is formed in the oxygen concentrating membranes into the car compartment. CONSTITUTION:In an oxygen concentrating device 70, oxygen concentrating membranes 82 are laminated between the partitioning walls 83 in a hollow body 81, and the air taking-in port 84 of the hollow body 81 communicates to the main duct 75 for taking in air on which a blower motor 73 and an air filter 72 are installed. The space in the hollow body 81 communicates to the suction side of a vacuum pump 71 through an oxygen taking-out duct 77, and an oxygen feeding duct 74 to the car compartment is connected on the discharge side of the vacuum pump 71. In the above-described air conditioner, an oxygen sensor 3 for detecting the oxygen concentration is installed into the car compartment, and the result of the detection is input into an air conditioning control unit 500. Then, the above-described pump 71 and the motor 73 are controlled so that the result of the detection of the oxygen sensor 3 becomes always constant. |
