PROBLEM TO BE SOLVED: To make it possible to reduce the size of a supply air duct or omit the duct laid out in an equipment space in an attic or the like and supply a special treatment fluid indoors. SOLUTION: An air conditioning system 1 is laid out in a ceiling of a building, thereby constituting an air conditioning unit which extends along the ceiling. Cold water or hot water is arranged to flow in a pipeline 31 connected to a cold heat source and a hot heat source, thereby cooling or heating the air in a piping spacing area 2a. A multi-purpose pipeline 3 is connected to an air source of a specially treated air and thereby conveys the specially treated air force-fed from the air source and discharges the air into the piping housing space 2a by way of a discharge hole. The specially treated air discharged into the piping housing area 2a is mixed with the air in the cooled or heated piping housing area 2a or cooled or heated with the air so that the air may flow out indoors by way of a vent hole 22. |
