Air Conditioning Control for Large Offices

In large buildings, heat source equipment such as boilers and freezers are commonly installed in machine rooms to provide overall air-conditioning.
Each story has an air handling unit (AHU) that distributes cooled (or heated) air to the floor. The air flow from the AHU is increased or reduced at a damper motor that is controlled by a variable air volume (VAV) controller. It receives the readout on the wind sensor and the temperature setting on the remote controller, and adjusts the aperture of the damper to keep room temperature as close to the preset one as possible.
