Heating ventilation, and air conditioning unit for automotive vehicles
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.
