摘要： A control load is reduced in a fan unit capable of controlling air flow volume. The rotation speed of a fan can be changed. An air flow volume detector detects air flow volume of the fan or equivalent air flow volume that is a physical quantity corresponding to the air flow volume of the fan. A unit casing houses, therein, the fan and the air flow volume detector. A fan controller, which is a controller, controls the rotation speed of the fan. The fan controller controls the rotation speed of the fan on the basis of a command value of the air flow volume of the fan given from outside the unit and a detected value of the air flow volume or the equivalent air flow volume detected by the air flow volume detector.

摘要： An air treatment system controls airflow volume in accordance with momentarily varying airflow volume to be demanded. A supply fan unit is disposed separately from an air treatment unit, and sends outdoor air from an outdoor space to the air treatment unit and sends outdoor air treated by the air treatment unit to an indoor space. An exhaust fan unit is disposed separately from the air treatment unit, and sends indoor air from the indoor space to the air treatment unit and sends indoor air treated by the air treatment unit to the outdoor space. A controller controls a rotation speed of a first fan in accordance with a first detection value of a first airflow volume detection unit, and controls a rotation speed of a second fan in accordance with a second detection value of a second airflow volume detection unit.

摘要： The present disclosure controls the supply of conditioned air to moderate the energy consumption by the heat source side in the supply of conditioned air using ducts in an air conditioning system. A heat exchanger unit includes a use side heat exchanger. A plurality of ducts distribute conditioned air that has passed through the use side heat exchanger of the heat exchanger unit. A plurality of fan units suction the conditioned air from the heat exchanger unit through the plurality of ducts, and supply the conditioned air to an air conditioned space. Each fan unit includes a fan motor that acts as an actuator configured to change an individual air supply amount of the conditioned air. A controller controls the plurality of fan motors to control the respective air supply amounts of the plurality of fan units.

摘要： 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.
