The opening degree of each damper 8 is adjusted to an arbitrary position in accordance with the temperature difference between the set room temperature set by the occupant in each room thermostat 19 and the detected current room temperature. Then, the pressure inside the main duct 6 changes according to the opening degree of the damper 8, which is detected by the pressure detector 18, and the capacity of the blower 5 is changed to reach a preset set pressure.

The air, which has been adjusted to a substantially constant temperature in this manner, is blown out into the room 1 from the air outlet 10 at an air volume that corresponds to the magnitude of the indoor heat load. The air that has been conditioned in the room 1 flows from the suction port 11 through a space such as a hallway to the ceiling suction port 12, and returns to the indoor unit 2 via the suction duct 14. The outside air was sucked in from the outside air intake port 13 by the blower 5, merged with return air, and entered the indoor unit 2.

定量より多くなフた場合には、不要な外気熱負荷が発生
し、また、取入れ外気量が設定量より少なくなった場合
には、外気による換気量不足となる。(Problems to be Solved by the Invention) However, in the conventional example as described above, the following problem occurs particularly in controlling the amount of outside air taken in. Namely, the opening degree of the wind M adjustment damper is changed to When you change the amount of air blown into a room, the amount of return air also changes, changing the balance between the intake outside air amount and the return air amount.As a result, it becomes difficult to maintain the intake outside air amount at the set amount, and the intake outside air amount changes. If the amount of outside air taken in is greater than the set amount, unnecessary outside air heat load will occur, and if the amount of outside air taken in is less than the set amount, the amount of ventilation due to outside air will be insufficient.

るため、実用的でない。In order to improve these phenomena, there is a device that detects the indoor carbon dioxide concentration and changes the amount of outside air taken in, but it is expensive and difficult to handle. In addition, a method of controlling the amount of outside air taken in based on the amount of latent heat generated indoors has been proposed, for example in Japanese Patent Laid-Open No.
Although this method has been proposed in Japanese Patent No. 48433, it is not practical because the amount of latent heat generated from indoor appliances may vary greatly.
