ABSTRACT:
Provided is an air conditioner for a vehicle, including a blower unit that blows air, an air conditioning case including an evaporator and a heater core, which are sequentially disposed in an airflow path, and an air inlet path that allows air to flow to an evaporator from the blower unit, wherein the airflow path includes a first path that allows air entered from the air inlet path to flow to a lower part of the evaporator and second and third paths that allow the air to flow to the lower part of the evaporator after passing through both sides of the evaporator. The air conditioner increases an amount of airflow and reduces airflow resistance since airflow paths are formed on both sides of the evaporator in addition to a direction perpendicular to the separator. Consequently, the airflow entering a lower part of the evaporator can be uniformly distributed.
