CONSTITUTION:A front seat air conditioner unit 1 is provided with an inside/ outside air switching door 5, a main blower 6, an evaporator 7, an air mix door 13, and a heater core 8 in sequence from the upstream side in a main duct 2 having inside and outside air inlets 3, 4 on the most upstream side. The rear seat duct 20 of a rear seat draft unit 19 is connected to the said main duct 2 at a rear seat air mix chamber 22 provided on the inlet side of a rear seat blower 21 via the first-third connecting passages 23a-23c. In this case, the connecting passage 23a is opened to a cold air passage 9 and the connecting passages 23b, 23c are opened to the main duct 2 on the downstream side of the heater core 8 respectively, and individual connecting passages 23a, 23b are provided with air mix doors 24, 25 respectively.</p> |
