置。[Scope of Claim for Utility Model Registration] An air conditioner for a vehicle that has at least an evaporator 13 that cools air blown into the vehicle interior and controls the temperature inside the vehicle interior to the temperature required by the occupants, which controls the temperature of the air outside the vehicle interior. A first air intake port 3 provided outside the vehicle interior or a second air intake port provided inside the engine room 5 which takes in air to be supplied to the evaporator 13, respectively.
An inlet switching means 9 for selectively switching one of the air inlets 7, and a driving means 14 for driving the inlet switching means 9.
and, when the temperature of the air outside the vehicle cabin detected by the outside air temperature detection means 15 is below a predetermined value,
The driving means 1 sends a signal to set the suction port switching means 9 to a position where the second air suction port 7 is opened.
On the other hand, when the temperature of the air outside the vehicle compartment is higher than a predetermined value, the drive means 14 outputs a signal to set the intake port switching means 9 to a position where the first air intake port 3 is opened. An air conditioner for an automobile, comprising: a control means 20 for outputting an output to the air conditioner.
