PURPOSE:To perform more efficient air conditioning operation of a perimeter zone without adversely affecting an interior zone. CONSTITUTION:A chamber 4 is installed to the inside of a window base 3 in the lower part of a window side in a perimeter zone 2 where an air outlet 4a is provided in the upper part. An air conditioner 8 installed outlet is provided with a ventilation fan 10 and an air supply fan 13. The lower part of the chamber 4 is connected to the air conditioner 8 by way of an air supply duct 14. The controlled air is fed to the air supply duct 14 by the air supply fan 13 so as to introduce the air into the chamber 4. An air suction box 7 is installed in the ceiling by the window side where the air suction box 7 is provided with an air inlet 7a in the ceiling. The air suction box 7 is connected to the air conditioner 8 by way of a ventilation duct 9 so as to suck up the air in the ventilation duct 9 by means of the fan 10 and return the air to the air conditioner 8. The controlled air blown off from the air outlet 4a rises while it is air conditioning the window side and the air which is absorbed from the air inlet 7a returns to the air conditioner 8 by way of the ventilation duct 9. |
