Claims

[Scope of utility model registration request]

It has an air conditioning unit placed at a predetermined location on the vehicle body, and the air conditioning unit includes a main suction port opening into the vehicle interior, an inside air intake port communicating with the suction port, an outside air intake port, and the inside air and outside air introduction ports. a ventilation system having an evaporator blower that sucks air inside the vehicle and outside air toward the evaporator through its mouth, and an exhaust blower that discharges a portion of the air inside the vehicle introduced through the inside air intake to the outside of the vehicle through the exhaust port; In the vehicle air conditioner, the air conditioner has a suction port that opens at a location away from the main suction port in the vehicle interior, and the air inside the vehicle that enters from the suction port is connected to the main suction port and the inside air introduction port. at least one suction duct leading to the passage; an exhaust duct connected to the middle of the suction duct and having an exhaust port to the outside of the vehicle; and an exhaust duct provided upstream of the connection port of the exhaust duct in the suction duct. 1. A vehicle air conditioner equipped with a ventilation system, comprising an intake blower and a switching door provided in the intake duct to open and close the connection port.
