To mitigate eccentricity of temperature distribution within an air conditioning area.SOLUTION: In a supply line L of conditioning air from a VAV 5 to a branch pipe 8, a switching device 9 is installed for switching a feed destination of the conditioning air to the branch pipe 8, and a switching state of the switching device 9 is controlled by a control device 10. When the switching device 9 is brought into a first switching state, a first duct port 8a of the branch pipe 8 is defined as a feed destination of conditioning air, and a second duct port 8b is closed. When the switching device 9 is brought into a second switching state, the second duct port 8b of the branch pipe 8 is defined as a feed destination of conditioning air, and the first duct port 8a is closed. Thus, for example, a blowing direction of conditioning air flowing in the branch pipe 8 is periodically switched, such that distances of piping routes from the VAV 5 to a blow-out port 7 are switched. Thus, an entire air volume of conditioning air blown out of the blow-out port 7 is balanced, thereby mitigating eccentricity of temperature distribution in an air conditioning area 4.SELECTED DRAWING: Figure 1 【課題】空調エリア内における温度分布の偏りを緩和させる。【解決手段】ＶＡＶ５から支管８への調和空気の供給路Ｌに、支管８への調和空気の送り込み先を切り替える切替装置９を設置し、この切替装置９の切替状態を制御装置１０によって制御する。切替装置９を第１の切替状態とすると、支管８の第１の管路口８ａが調和空気の送り込み先とされるとともに第２の管路口８ｂが塞がれ、切替装置９を第２の切替状態とすると、支管８の第２の管路口８ｂが調和空気の送り込み先とされるとともに第１の管路口８ａが塞がれる。これにより、例えば周期的に、支管８を流れる調和空気の送風方向を切り替えるようにして、ＶＡＶ５から吹出口７までの配管経路の遠近を入れ替え、吹出口７から吹き出される調和空気の全体的な風量のバランスを取るようにして、空調エリア４内における温度分布の偏りを緩和させることができるようになる。【選択図】 図１
