Air conditioner for vehicle

Abstract

Disclosed is an air conditioner for a vehicle that enables precise temperature control when mixing cold air and warm air and reduces the resistance in a warm air passage, thus increasing the air volume. The air conditioner for a vehicle includes an air conditioning case having an air passage formed therein, and a cooling heat exchanger and a heating heat exchanger sequentially provided in the air passage in an airflow direction, wherein the air passage includes a cold air passage through which air passing through the cooling heat exchanger bypasses the heating heat exchanger and a warm air passage through which air passing through the cooling heat exchanger passes through the heating heat exchanger, a first temperature door for controlling the opening degree of the cold air passage and a second temperature door for controlling the opening degree of the warm air passage are provided, and when the second temperature door opens the warm air passage, the second temperature door guides the warm air passing through the heating heat exchanger to the cold air passage.
