Room temperature control with variable air volume
Ventilation systems, usually with temperature or air quality control, supply rooms and zones in buildings with preconditioned air. Modern comfort ventilation systems can achieve high energy savings without any loss of comfort by adapting the air volumes supplied to the actual requirement which varies according to the utilization profile and time of day. This is effected by means of communication between the OpenAir VAV controllers and sensors at room level and the controllers of the central AHU devices.
Bus communication further increases plant transparency through simultaneous monitoring of several communication objects and parameters in a management system.
