Abstract
Abstract An air conditioner system for a vehicle includes a front-seat air conditioner unit, a rear-seat blower unit, and at least one connecting passage interconnecting a main duct of the front-seat air conditioner unit and a rear-seat duct of the rear-seat blower unit. The front-seat air conditioner has a main blower to blow air into a front-seat part, and the rear-seat blower unit has a rear-seat blower to force blown-off air into a rear-seat part. The main blower and the rear-seat blower are controlled with a relationship between them and predetermined patterns. The main blower supplies additional blown air into the rear-seat part when needed.
