- each of the blowing units 20 of the usage-side unit 2 is connected to the main body portion 10 by a duct 30. Therefore, each of the blowout units 20 can be installed at a position where the blowout port 21 is in the vicinity of each side of the air conditioning area 101. That is, the air outlets 21 can be arranged on the outer peripheral side as much as possible in the air conditioning area 101 in a plan view. Further, in the air conditioning system 1 according to the first embodiment, the direction of the air blown out from each of the blowout units 20 during the air conditioning operation is the center of the air conditioning area 101 with respect to the vertical line by the vertical wind vane 23. Tilt in the 102 direction.
- the temperature-controlled air blown from each of the air outlets 21A to the air conditioning area 101 flows from the outer peripheral side toward the center in the air conditioning area 101A. And after that, it flows to the outer peripheral side in the air conditioning area 101A again, and flows out from the air conditioning area 101A to the air conditioning area 101B. Therefore, the temperature-controlled air blown out from each of the outlets 21A to the air-conditioning area 101A has a longer residence time in the air-conditioning area 101A, and after sufficiently exchanging heat with the air in the air-conditioning area 101A, the air-conditioning Flows out to area 101B.
- the use side unit 2A installed in the air conditioning area 101A is in cooling operation, it is possible to sufficiently supply cold heat to the air in the air conditioning area 101A. Therefore, when the air blown out from each of the air outlets 21A to the air conditioning area 101A flows out to the air conditioning area 101B, the temperature is almost the same as that of the air in the air conditioning area 101A in a state where there is almost no cold. Moreover, when the utilization side unit 2A installed in the air conditioning area 101A is in a heating operation, it is possible to sufficiently supply the heat to the air in the air conditioning area 101A.
