Abstract

The invention concerns a method and equipment for determination of resistance values (k1, k2...) of an air-conditioning system's distribution networks (N1; U1, U2...; O1, O2...) in an air-conditioning system. In the method, the difference is calculated between the airflow measured in the room duct (O1, O2...) by an indicator (e1, e2...) or such and the airflow given by a distribution network model (150) into the concerned room duct (O1, O¿2...), and if the said difference is outside a certain predetermined tolerance range, the calculation to determine resistances, that is, the calibration calculation performed by a calculation unit (100) is used to change the distribution network resistances (k1, k¿2...) of the distribution network model (150), and the said calculation is performed again. When the difference between the measured flow rate and the calculated flow rate is within the tolerance range, the calculation is finished, whereby the resistances (k1, k2...) determined last represent the final distribution newtork resistances.
