• the second mixing chamber 18 is arranged fluidly between the sliding shutter 38 previously described and a shutter 56 movable essentially between an open position, visible in Figure 3, in which it allows the passage of a second mixed air flow 58 resulting from the mixing of the first air flow 12 and the second air flow 14 in the second mixing chamber 18 towards the second air outlet 22 and a closed position, visible in FIG. 2, in which it prevents the circulation of the second mixed air flow 58 from the second mixing chamber 18 towards the second air outlet 22 directed towards the rear zone of the passenger compartment.
• the shutter flap 56 is tilted into its open position when the rear zone of the passenger compartment requires heat treatment and into its closed position when the rear zone of the passenger compartment does not require heat treatment, for example due to the absence of a rear passenger. This limits the energy consumption of the heat exchanger only when necessary.
• Advantage is taken of the sliding shutter according to the invention, and in particular of its displacement in translation in the box in that it makes it possible to maintain an optimal volume of the second mixing chamber, and thus to improve the mixing between the first flow of air and the second air flow within said second mixing chamber by causing this mixing from the start of the mixing chamber, that is to say as soon as the air flow has crossed the first mouth and the second mouth.
