<P>PROBLEM TO BE SOLVED: To surely restrain fuel consumption and save energy when a cooling operation is performed in an inside air circulation mode. Ž<P>SOLUTION: In an air conditioner 10, an inside air inlet port 24 opened on an undercover 40 below an instrument panel is formed, and an introduction duct 88, on which the inside inlet port is formed, is connected to a blower unit 20. An intermediate part of the introduction duct is connected to a front heater duct 52, and a passage switch door 92 is provided to a connection part 90. An air-conditioner ECU is set to an inside air circulation mode. When a FACE mode or a DEF mode applied to a cooling operation is selected as a blowing mode, the passage switch door is operated to a position S2. Thereby, the air inside a compartment air-conditioned from the inside air inlet port and a front seat step blowing port 50 is introduced and used for generating air-conditioning winds, so as to reduce an air-conditioning load and save energy.
