In an air-conditioning installation of a compartment such as an aeroplane cabin, inside a vehicle etc., each of the individual ventilation orifices (10) is equipped with a mixer (19). This mixer makes it possible, by means of a lever (30) acting on a movable flap (20), to control the temperature of the air delivered by the corresponding orifice (10), by opening to a greater or lesser extent the ends of two pipelines (18a, 18b) which convey the air at two different temperatures. <IMAGE>
