PROBLEM TO BE SOLVED: To provide a thermal stratification type air conditioning system in which sufficient energy saving is attained in cooling in summer, air conditioning for heating can be performed uniformly without temperature or humidity unevenness in heating in winter while suppressing the occurrence of cool air accumulation at the foot by suppressing a cold draft while operating an air conditioner with the same air volume as that in summer, and further, a floor space can be utilized efficiently to a maximum.SOLUTION: For an air conditioner 3, a loop duct 5 is disposed in such a manner as to form a closed loop as a whole at a preset height level L in a perimeter zone that becomes a boundary inside of a building 1 with the outside. A cooling coil for cooling air and a heated water coil for heating air are incorporated, and cooling/heating air is sent through a supply duct 6 to the loop duct 5. The air conditioner 3 is provided at the same height level as that of the loop duct 5, and an air blowing nozzle is inserted and disposed on a bottom face of the loop duct 5, in a length direction of the loop duct 5 and at a preset pitch P. A return air port 4 is disposed at the same height level as that of the loop duct 5 so as to suck air within the building 1 into the air conditioner 3. |
