<P>PROBLEM TO BE SOLVED: To provide a displacement air conditioning system capable of stably forming a uniform low-temperature clean zone with a very slow wind speed in a living zone. <P>SOLUTION: A displacement air conditioning system 10 blows conditioned air supplied from an air conditioner 11 at a slow wind speed into an air-conditioning object space 13 from a plurality of blowout ports 14 which are continuously arranged in a horizontal direction near the floor surface 13f of the air-conditioning object space 13 in a building 12, and discharges air from the ceiling surface 13c of the air-conditioning object space 13. The system includes, as the supply route of the conditioned air, a plurality of branch ducts 16 branching from a main duct 15 connected to the air conditioner 11, and a branch box 17 branching into ducts 18 in two directions from the branch duct 16. The system includes a VAV 19 disposed in the branch duct 16 upstream the branch box 17, a flow volume adjusting damper 20 for adjusting a small flow volume disposed in the duct 18 downstream the branch box 17, and a chamber 24 and the blowout port 14 connected to the duct 18 downstream the flow volume adjusting damper 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
