Abstract
An air supply system moderates excess energy consumption occurring in fans. A second unit includes a second fan that supplies first air to a target space. A duct sends the first air sent from a first unit by a first fan to the second unit. A remote sensor acting as a first detector detects information about second air in the target space. A main controller acting as a first controller communicates with the second unit and the remote sensor. The second unit includes a second detector that detects the air flow volume sent by the second fan, and a sub-controller acting as a second controller that controls the rotation speed of the second fan. The main controller determines a target air flow volume of the second unit on the basis of the information about the second air acquired from the remote sensor, and transmits an instruction indicating the target air flow volume to the sub-controller. The sub-controller controls the rotation speed of the second fan such that the air flow volume detected by the second detector approaches the target air flow volume.
