PURPOSE:To improve the efficiency and reduce the cost by making a polygonal branch chamber of upper and lower two tiers comprising taking-in and blowing- off branch chambers to connect a plurality of blowing-off branch ducts to the blowing-off chamber so as to take in air through the taking-in branch chamber. CONSTITUTION:An air conditioning device 10 has a taking-in main duct 11 and a blowing-off main duct 12 connected to an indoor air conditioner 1, and these ducts 11, 12 are connected to a branch chamber 13 of an arbitrary polygon. In addition, the branch chamber 13 is of an vertical two-tier structure having a partition 16 provided between a taking-in branch chamber 14 and a blowing-off branch chamber 15. Taking-in ducts 19 are connected to the taking-in branch chamber 14 and blowing-off ducts 20 to the blowing-off branch chamber 15. By the constitution, air in each room is taken in through the taking-in branch chamber while conditioned air is supplied to each room through the blowing-off branch chamber. |
