AIR CONDITIONER FOR VEHICLE

Japanese Patent JPS6271715

A

PURPOSE:To prevent the excessive cooling or low-temperature burn by connecting an air conditioning unit and a seat by a seat air conditioning duct equipped with a blower for reversible revolution and installing a damper for selectively opening and closing said duct and a ventilation duct. CONSTITUTION:When a recycle duct 14 is in opened state, the conditioned air is introduced into a duct 7 for seat air conditioning from a ventilation duct 1, and blown out from the ventilation hole of a seat 8 by the normal revolution of a blower 6 for seat air conditioning, and the seat 8 can be air-conditioned. When the excessive cooling or warming is detected, an automatic control circuit for seat air conditioning is operated to operate a ventilation damper 14, and the communication between the ventilation duct 1 and the duct 7 for seat air conditioning is cut off, and the blower 6 is revolved in the reverse direction, and the car-interior air is inhaled from a communication hole, and introduced into the upstream side of the ventilation duct 1. With such constitution, the excessive cooling or low-temperature burn can be prevented.
