In modern buildings, individual rooms or zones are supplied with fresh air. Outside air is preconditioned in air purifier units (clean, heat, cool, humidify, dehumidify) and fed to the individual rooms and zones via an extensive duct system. Near the air outlets there are dampers that control the air supply to the zones or rooms. OpenAir™ air volume controllers not only measure the air volume precisely, but also co-ordinate the opening and closing of the dampers exactly with the air requirement.
This controlled air supply, called “variable air volume”, ensures that rooms and zones receive exactly the amount of cooled or outside air that they need. The result is a higher level of comfort and efficiency.
