<p>A system for ventilating spaces via several ventilation ducts (1) including detection means for detecting air variables in those spaces or ventilation ducts, respectively. In those spaces, a measurement and control unit (3) can set or change, respectively, ventilation parameters by means of regulating valves (2) in the respective ventilation ducts. The detection means comprise per group of ventilation ducts one common sensor module (6) adapted for periodically, per ventilation duct or subgroup of ventilation ducts, measuring and transmitting one or more air variables to the control means. Through drive means (7), the sensor module can be periodically brought into contact with each ventilation duct belonging to said group or each subgroup of ventilation ducts, respectively. The ventilation ducts terminate in the detection space by means of exhaust openings (4) along which the drive means proper the sensor module. The collecting space (5) is connected to a common air discharge (8) having a common fan (9) therein. The control valves (2) can be set by a central actuator (12) which is propelled by the same drive means (7) as the sensor module and which is controlled from the measurement and control unit (3).</p> |
