ABSTRACT:
A method for operating a heating or air conditioning system, especially for motor vehicles is provided, in which a temperature control fluid is drawn in via a discharge blower whose discharge power can be regulated, and is blown out after processing through at least one exhaust duct, whose outlet cross section can be regulated via a corresponding controllable control element. Each control element for outlet cross section regulation is automatically adjusted to assume a position that depends upon the outlet temperature of the temperature control fluid. The discharge blower power is adjusted according to a curve as a function of this outlet temperature. This curve is determined as a function of the positions of the control elements that regulate the outlet cross section and the total outlet cross section of the system thus determined in such fashion that an essentially constant temperature control fluid outflow rate is achieved regardless of the outlet temperature of the temperature control fluid and hence independently of the different positions of the control elements that regulate the outlet cross section.
