Abstract:
Installation for air-conditioning of the passenger compartment of a vehicle, comprising a casing containing means for treating an airflow to be sent into the passenger compartment, said means including at least one of a heat and a cold source and changeover-switching elements (20, 21, 29, 30, 34, 41, 43) controlled in such a way as to define variable paths for said airflow between an inlet and various outlets associated with respective regions of the passenger compartment, selectively passing through said at least one of a heat and a cold source, wherein the casing further contains two substantially vertical partitions (10, 11) traversed by said at least one of a heat and a cold source and separating, from one another, three path elements passing through the at least one of a heat and a cold source, two of the said path elements (22), which are connected to at least one first outlet (25, 27, 38, 49) linked to at least one first region of the passenger compartment being separated by the two partitions respectively from the third path element (31), which is connected to a second outlet (40) linked to at least one second region of the passenger compartment, andwherein each of said path elements passing through the at least one of a heat and a cold source is in parallel with a separate path element avoiding the at least one of a heat and a cold source, the sharing of the air between said path elements passing through the at least one of a heat and a cold source and said separate path element being undertaken by the changeover-switching elements (20, 21, 34); and the changeover-switching elements comprise at least one shutter element (41) suitable for shutting off the second outlet and for diverting the air flowing in the corresponding path elements to the first outlet (27, 28a).
