PURPOSE:To contrive to reduce the initial cost and running cost for air conditioning facility by a method wherein either one of two rooms adjacent to each other is air-conditioned selectively at will by means of a single air conditioning indoor unit having an air conditioning capacity for a single room. CONSTITUTION:On-off dampers 12, 13, 14 and 15 are installed on the respective air suction ports 8 and 10 and air blow-off ports 9 and 11 in the order named. A group of the dampers 12 and 14 and a group of the dampers 13 and 15 are respectively and separately open and closed under the control of a control board. When the dampers 12 and 14 are closed and the dampers 13 and 15 are open under the state that a room 1 is air-conditioned, the air-conditioning of the room 1 is stopped and that of a room 2 is started. In other words, the rooms 1 and 2 are selectively air-conditioned by means of a single air conditioning indoor unit 4. Thus, the single air conditioning indoor unit 4 can selectively air-condition either one of two rooms, which are adjacent to each other and the simultaneous use of both of which is scarce. |
