Control device for ventilation and air conditioning systems

Control device for room air managing systems, comprising at least:

• one or more rooms (32,34) or room zones;
• an inlet air channel (22) and room inlet air channels (22a) branching therefrom;
• an exhaust air channel (20) and room exhaust air channels (20a) branching therefrom;
• an inlet ventilator (16) in said inlet air channel (22);
• controllable inlet air throttle flaps (14), said controllable inlet air throttle flaps (14) controlling inlet air flow in said inlet air channels (22a) interconnected with said one or more rooms or room zones;
• controllable exhaust air throttle flaps (12), said controllable exhaust air throttle flaps (12) controlling exhaust air flow in said room exhaust air channel (20a) interconnected with said one or more rooms or room zones;
• a pressure sensor (38) in each one or more rooms (32, 34) or room zones, said pressure sensor detects room pressure in said room (32, 34) or room zone that is to be air conditioned;
• said room pressure constitutes the direct control parameter for positioning said inlet air throttle flaps (14) and/or said exhaust air throttle flaps (12).
