The air conditioner is driven in such a state that blowing-out air switching dampers 16 and 17 which lead the air blown out from the fan 3 and passed through heat exchangers 8 and 9 to the inside R of the room or outside U by switching the indoor blowing-out flow passages 10 and 11 and outdoor blowing-out flow passages 12 and 13 are linked to the indoor and outdoor air suction dampers 14 and 15.
