PROBLEM TO BE SOLVED: To efficiently prevent the frosting of an evaporator and the generation of a sense of incongruity in an occupant when stopping air conditioning on a front seat side and carrying out air-conditioning on a back seat side. SOLUTION: In an air conditioning system 10, air conditioning by a front air conditioner 12 by using the evaporator 20, and cooling by a rear cooler 14 using the evaporator 20 can be independently carried out. On an air conditioning duct 30 of the front air conditioner, a discharging port opened into an instrument panel and a discharging damper 98 opening and closing the discharging port are provided. When the rear cooler is operated while the operation of the front air conditioner is stopped, a blower fan 44 is driven, and the discharging damper is driven to open the discharging port and discharge cooled air conditioning wind into the instrument panel. A temperature rise in the instrument panel can be suppressed while preventing the frosting of the evaporator and the incompatible feeling of the occupant. COPYRIGHT: (C)2007,JPO&INPIT
