Abstract: A vehicle air conditioning device is disclosed. The air condition device includes an air conditioning case having a passage in which air flows, a blower connected to the air conditioning case for blowing the air, a cooler and a heater housed in an interior of the air conditioning case, and a duct provided in the air conditioning case for conveying the air that has been temperature controlled by the cooler and the heater. The passage includes a cool air passage in which the cooler is disposed, a warm air passage in which the heater is disposed, and an introduction passage provided between the cool air passage and the warm air. A switching door is provided in the introduction passage for controlling an amount of the air flowing to the cool air passage and the warm air passage.

Abstract: In a vehicular air conditioning apparatus, a first partitioning member and a second partitioning member are installed at a boundary position between a first cooling section and a second cooling section of an evaporator. The evaporator is separated into the first cooling section and the second cooling section by the first and second partitioning members. In the case that air is not blown in either one of the passages that are disposed in the first cooling section and the second cooling section, air that flows through the other of the passages is prevented from flowing into the one passage through the interior of the evaporator.

Abstract: In a vehicular air conditioning apparatus, a first blower unit is connected by a connection duct to a side portion of a casing having respective air passages defined therein, and a second blower unit separate from the first blower unit is connected to a lower portion of the casing. In addition, air that is supplied to the interior of the casing from the first blower unit and air that is supplied to the interior of the casing from the second blower unit are prevented from mixing together mutually inside the casing by first and second ribs, and by ribs, which are formed respectively to face toward an evaporator and a heater core.

Air that is supplied to the interior of the casing from the first blower unit and air that is supplied to the interior of the casing from the second blower unit are prevented from mixing together mutually inside the casing by a pair of ribs, which are formed to face toward a heater core.
