Abstract:
An air conditioner for a vehicle having a passenger compartment, said air conditioner comprising:a case for defining an air passage through which air flows into the passenger compartment, said case at one end side having an outside air introduction port from which outside air outside the passenger compartment is introduced and an inside air introduction port from which inside air inside the passenger compartment is introduced, and at the other end side having a front air opening for blowing air toward a front seat side of the passenger compartment and a rear air opening for blowing air toward a rear seat side of the passenger compartment, said front air opening including a front face opening for blowing air toward an upper front side of the passenger compartment, a front foot opening for blowing air toward a lower front side of the passenger compartment and a defroster opening for blowing air toward an inner surface of a windshield of the vehicle;a blower unit for blowing inside air and outside air while partitioning inside air and outside air from each other;a partition member for partitioning said air passage into a first air passage through which outside air from said outside air introduction port flows into said front air opening by said blower unit, and a second air passage through which inside air from said inside air introduction port flows into said rear air opening by said blower unit, when both said outside air introduction port and said inside air introduction port are opened;a heating heat exchanger for heating air flowing through said first air passage and said second air passage; anda switching unit which selectively opens and closes said front face opening, said front foot opening and said defroster opening to at least set a first mode where both said front face opening and said front foot opening are opened, and a second mode where both said defroster opening and said front foot opening are opened, wherein,when said partition member partitions said first air passage and said second air passage from each other during a double layer flow mode, inside air in said second air passage flows into said rear air opening, and outside air in said first air passage flows into both said front face opening and said front foot opening among said front air opening in said first mode and flows into both said front foot opening and said defroster opening among said front air opening in said second mode.
