An air conditioner 100 is provided with an air conditioner main body 10 installed in a building 2 of a factory 1 and an air intake duct 11 and a blower duct 12 connected to the air conditioner main body 10 . The air conditioner body 10 includes a heat source device (not shown) and a blower fan (not shown). is configured to

The air conditioner 100 includes one or more normal ducts 12N branched from a main duct 12M connected to the air conditioner body 10, and one or more flexible ducts 12F. The air conditioner 100 directs the conditioned air CA blown out from the air conditioner main body 10 to a certain area in the factory 1 from the normal connection port 13N connected to the normal duct 12N via the main duct 12M and the normal duct 12N. In addition to enabling air to be blown toward the worker P1, air can also be blown toward the worker P2 moving in the factory 1 from the movable air outlet 13F connected to the flexible duct 12F via the main duct 12M and the flexible duct 12F. do.

The moving worker P2 can be assumed to be a worker who moves irregularly within the factory for work, or a worker who is always on the move in a delivery vehicle, such as in physical distribution work.

Therefore, the air conditioner 100 has a flexible duct 12F that connects the air conditioner main body 10 and the mobile air outlet 13F. and a control means 40 that follows the operator P2 detected by the detection means 30 and controls the unmanned air vehicle 20. In this embodiment, the detection means 30 and the control means 40 are mounted on the unmanned air vehicle 20 in the form of being provided at the air outlet 13F.

Examples of the unmanned flying object 20 include a so-called drone that flies three-dimensionally in space without a person on board. As shown in FIG. 3, the unmanned flying object 20 includes a main body 21 provided with a control means 40, a base 22 on which the main body 21 is mounted, and a plurality of controllers provided on the base 22. propeller 23, a casing 27 attached to the lower surface of the base 22 via, for example, a hollow cylindrical attachment 26, and legs extending downward from the base 22 to support the unmanned aircraft 20 in the landing state. 28 and. Each propeller 23 has a shaft portion 24 connected to the rotating shaft of a motor (not shown) and blades 25 attached to the shaft portion 24. As the shaft portion 24 rotates, the blades 25 rotate. is configured to generate an upward lift force by the rotation of the By controlling the rotation of a plurality of propellers 23, the unmanned air vehicle 20 can take off, fly, land, and hover to stop in the air.

A battery (not shown) is provided inside the base portion 22 or the casing 27, and power for the motor of the unmanned flying object 20, the detection means 30, and the control means 40 is obtained from the battery. It's like
