VENTILATION GROUP WITH VARIABLE POWER ACCORDING TO PRESSURE SATISFACTION SATISFACTION PROBABILITY

摘要

The ventilation unit comprises a power supply unit of an air circulation fan motor in mouths distributed on columns, controlled by conversion circuits which, starting from predetermined optimum values of pressure corresponding to an optimal curve. (KM) satisfactory response pressure (Dp) / flow (Q) regardless of the distribution of open mouths, associated with each air flow (Q) measured, a Gaussian (G1, G2, G3, G4), risk of non-satisfaction of the pressure requirement (Dp), increasing as soon as a desired set-point air pressure decreases below the corresponding optimum value, and which set the target air pressure to a value determined according to a set percentage of said risk, provided by an integral of the Gaussian (G1, G2, G3, G4).
