An air conditioning system includes: an intake unit configured to take in return air of an indoor space from a ceiling of the indoor space; an outdoor air processing unit configured to supply outdoor air while exhausting the return air taken in via the intake unit to outdoors; an air conditioner configured to supply, as air-conditioning air, mixed air of the return air taken in via the intake unit and the outdoor air supplied by the outdoor air processing unit; and at least one radiation unit disposed in the indoor space in a manner to surround the intake unit, the radiation unit being configured to radiate heat of the air-conditioning air supplied by the air conditioner while discharging the air-conditioning air to the indoor space.

Air conditioning system

A pneumatic radiation unit according to the present invention includes: a first chamber including a first air discharger configured to discharge air-conditioning air to a second chamber; and the second chamber including a second air discharger configured to discharge the air-conditioning air to a space to be air conditioned, the second chamber being configured to take in the air-conditioning air from the first chamber and discharge the air-conditioning air and radiate heat to the space to be air conditioned. A second aperture ratio of the second air discharger is set to be greater than a first aperture ratio of the first air discharger, or a cross-sectional area of a flow passage of the air-conditioning air in the first chamber is gradually reduced from an upwind side to a downwind side of the flow passage of the air-conditioning air.

Pneumatic radiation unit

A pneumatic radiation air conditioner includes: a radiation unit configured to radiate air-conditioning air; and a fan configured to feed the air-conditioning air to the radiation unit. The radiation unit includes: a first chamber, through which the air-conditioning air flows; a second chamber configured to take in the air-conditioning air discharged from the first chamber and discharge the air-conditioning air and radiate heat of the air-conditioning air to a space to be air conditioned; and an air stream adjuster configured to adjust air velocity distribution and air volume distribution of the air-conditioning air that is discharged from the first chamber to the second chamber.
