Mixer assembly and method for operating a mixer assembly

A mixer assembly for an air-conditioning system, comprising:

• a recirculation air line, which is connectable to a region of a vehicle to be air-conditioned, in order to remove recirculation air from the region of the vehicle to be air-conditioned,
• an air-conditioning air line, which is connectable to an air-conditioning unit in order to remove air-conditioning air, generated by the air-conditioning unit, from the air-conditioning unit,
• a first mixing region, connected to the recirculation air line and to the air-conditioning air line, for mixing the recirculation air from the recirculation air line with the air-conditioning air from the air-conditioning air line,
• a second mixing region, connected to the recirculation air line and to the first mixing region, for mixing mixed air from the first mixing region with further, pure recirculation air from the recirculation air line,
• a first supply line, which is connected to the first mixing region and which is adapted to supply mixed air from the first mixing region to a first partial region of the vehicle region to be air-conditioned, and
• a second supply line, which is connected to the second mixing region and which is adapted to supply mixed air from the second mixing region to a second partial region of the vehicle region to be air-conditioned.
