Vehicle air conditioner with heater and evaporator contained in air guidance casing, inclines them at acute angle to horizontal plane, with optional partial overlap

摘要

The heater (H) and evaporator (V) planes pass airflow at right angles. Each includes an angle with the horizontal plane (E), which is preferably less than 30[deg]. They (H, V) are located close together. Alternatively they overlap partially. When projected onto the horizontal plane, their areas overlap by no more than one half the projected area of the heater. They are inclined in the same- or opposite directions. The arrangement is V-shaped. Further relative dispositions and siting locations of the units (H, V) in the vehicle are proposed.
