An air conditioning unit for a vehicle has a unit case enclosing a blower fan, a cooling heat exchanger (evaporator) and a heating heat exchanger (heater core), and defining therein an air conditioning passage for conveying air from the blower fan through the cooling heat exchanger and the heating heat exchanger, to an upper outlet opening. The air conditioning passage has an upstream passage section extending downward on a first side of the blower fan to convey the air from the blower fan downward, an intermediate passage section extending under the blower fan in a first direction from the first side to a second side of the blower fan, and a downstream passage section extending upward on the second side of the blower fan to the upper outlet opening for directing the air over the blower fan in a second direction, opposite to the first direction, from the second side toward the first side (toward the passenger compartment of the vehicle).

Air conditioning apparatus for vehicle

In an automobile heating, ventilation, and air conditioning unit, an air-purifying filter is slanted and arranged in an upstream air duct defined in a HVAC unit case, so that the upstream end of the filter is supported by an upper supporting portion fixedly connected to the unit case for supporting the evaporator core and so that the downstream end of the filter is located away from the lower end of the evaporator core. Foot vent ducts are partitioned and formed in the unit case, utilizing the dimensional difference between the evaporator and heater cores in both height and width dimensions. Temperature-adjustment ribs, slanted and inwardly extending from the inner periphery of the forward wall of the unit case above the heater core, are provided close to foot vent outlets, so that the foot vent outlets face to a space defined just downstream of the temperature-adjustment ribs.
