Partition

A partition having an air blowing function of blowing air to a predetermined region, the partition comprising:

• a casing;
• a blower mechanism arranged in the casing;
• an electronic controller configured to control the blower mechanism;
• a blow-out port located on a side of the casing:
• an air passage provided in the casing, the air passage
• extending in a first direction in which air is delivered from the blower mechanism, and
• being formed such that a downstream end of an airflow in the air passage is closed,
• the blow-out port being arranged along the air passage,
• on a virtual plane facing the blow-out port and having a wind velocity between 0.55 m/s and 2.125 m/s, inclusive, an airflow with an average momentum per unit area from 0.05 kg/ms2 to 0.75 kg/ms2 being generated, the virtual plane being a vertical plane, and
• the controller being configured to control the blower mechanism such that a momentum of air blown out through the blow-out port irregularly changes on the virtual plane.
