An air conditioner housing having an evaporation device, a heating device, an air control device, an interior space in which air flow paths are formed, and having a housing which surrounds the interior space, is proposed. The air conditioner housing (1) is defined in that a first air flow path (15) and a second air flow path (17) are formed, and in that the air control device (9) has at least two mixing flaps (11, 13), a first mixing flap (11) of which is designed to the first air flow path (15), and a second mixing flap (13) of which is assigned to the second airflow path (17), and in that the mixing flaps (11, 13) each completely open the assigned air flow path (15, 17) in a first functional position and completely close it in a second functional position.
