A mixer assembly for an air-conditioning system comprising a recirculation air line, connectable to a vehicle region to be air-conditioned, to remove recirculation air from the region, and an air-conditioning air line, connectable to an air-conditioning unit to remove conditioned air from the air-conditioning unit. A first mixing region, for mixing the recirculation air with the conditioned air, is connected to the two air lines. A second mixing region, for mixing the first mixing region air with recirculation air, is connected to the recirculation air line and the first mixing region. Also, a first supply line is connected to the first mixing region to supply air from the first mixing region to a first partial region of the vehicle region, and a second supply line is connected to the second mixing region to supply air from the second mixing region to a second partial region of the vehicle region.
