<p>A ventilation control system for a space (1) divided into several compartments (2), wherein in separate compartments (2) an individual ventilation control has to be realised, is provided with a ventilation unit (7) contained in each compartment. Each of the ventilation units (7) comprises a ventilator (11), a control valve (12) for this ventilator and an air flow meter (13), with the control valve and the flow meter being included in a first control circuit to enable, in cooperation with a ventilation computer (4), adjustment of the degree of ventilation in this compartment. As soon as one of the control valves (12) in the compartments has reached a specific maximally open position, a central control unit (5) is activated by means of the ventilation computer (4) to enable speeding up of the ventilators (11) in the compartments. If required, the air flow in the compartments (2), the control valves (12) of which have not reached the above maximum position, can be throttled by means of the control valves (12). <IMAGE></p> |
