（６１，（力。As a conventional glaze air conditioner η, there is one shown in Fig. I, for example. In air conditioning, in order to maintain the air environment, a return air duct (IIK carbon dioxide accumulation detector) is installed, as well as an outside air intake duct (3), an exhaust duct) (4), and an air conditioner (5). ) Return air duct to ) (/α)
A remote stirring damper (OL (7), (s) is provided at each of the dampers (61, (s)) in response to a detection signal from the detector (2).
（８）の開度調整を行ない、室内の汚れた空気を外へ排

み、室内空気の清浄度を保つようにしている。By adjusting the opening of (8), the dirty air inside the room is exhausted to the outside, and the necessary fresh air from outside is sent into the room to maintain the cleanliness of the indoor air.

例）し７ている。Generally, a carbon dioxide g degree detector (2) is installed in the return air duct (1), and a signal is output from the opening degree adjuster (9) according to the difference between the signal from the detector and the adjustment of the damper opening degree. , each remote-controlled damper (6), (force), and the damper opening degree of (8) are controlled (proportional).

詰りで、ダクト圧力が変化した際、風量やエアバランス
を撮保できな（・などの問題点があった。However, in such conventional air conditioners, the control wind blower responds to changes in carbon dioxide concentration by controlling (proportional) the damper opening of a remote-controlled damper, so carbon dioxide concentration cannot be detected. When the opening degree of each damper changes and the air volume changes according to the signal from the damper (2), the duct system is different, so the duct resistance will be different, and therefore the pressure change at each damper inlet will be different. Also, since the opening degree of each damper is not proportional to the resistance change, even if the opening degree of each damper is controlled proportionally,
The changes in the scenery passing through the valley damper cannot be made the same. As a result, there is a possibility that the amount of outside air intake cannot be reliably secured, or conversely, control stability may be lacking due to the large number of outside air intakes, and the return wind h1 to the air conditioner may also change, causing the supply It has a negative effect on the air flow. Additionally, when the duct pressure changes due to a clogged filter in an air conditioner, there are other problems such as the inability to record and maintain the air volume and air balance.

バランスが生じるなどの問題点もみられた。Additionally, in winter and summer, there is a pressure difference between the inside and outside of the building due to the difference in temperature, which greatly upsets the balance between winter and summer, and wind pressure also causes an imbalance in the intake and exhaust of outside air. Problems were also observed.
本発明は、このような従来の問題点に着目してなされた
