Abstract
The invention concerns a procedure for controlling volumetric flow rate in air-conditioning installations, wherein the volumetric flow passing through an air-conditioning duct is controlled with the aid of a control (10) disposed in the air duct by opening or closing the control damper (11) or equivalent of the control (10). In the procedure, the control signal of the control damper (11) or equivalent air flow-controlling member of the control (10) is non-linearized on the basis of the effective characteristic curve of the control and of the desired effective characteristic curve. The opening and closing of the control damper or equivalent of the control is controlled with the aid of said non-linearized control signal function. The invention also concerns apparatus for controlling air flow.
