Method and arrangement for regulating air mixing in a heating or air conditioning system of a motor vehicle

An arrangement for regulating air mixing in a heating and/or air-conditioning system of a motor vehicle having a passenger compartment, comprising:

• an air-guiding housing having at least one recirculated-air intake opening and at least one fresh-air intake opening;
• an intake air control element for selectively supplying at least one of recirculated air and fresh air to the housing;
• a fan and at least one heat exchanger positioned in the housing for conditioning the supplied air;
• a plurality of distributing air-flow control elements for distributing conditioned air from the housing to different locations in the passenger compartment;
• and
• a control unit for controlling the proportion of recirculated air supplied by the intake air-flow control element as a function of the position of at least one of the distribution air-flow control elements.

A method for regulating air mixing in a heating and/or air-conditioning system of a motor vehicle having a passenger compartment, comprising:

• supplying at least one of recirculated air and fresh air to an air-guiding housing;
• conditioning the supplied air in the housing;
• distributing conditioned air to different locations in the passenger compartment by means of at least one air-flow control element;
• and
• controlling the proportion of recirculated air supplied primarily as a function of the position of said at least one air-flow control element.
