Air conditioning device for vehicle

Abstract

Abstract PURPOSE:To prevent an increase of the load applied to an evaporator arising from passing of the outside air through the evaporator when a car room is ventilated, by such constitution that the outside air from an outside air introducing port is partially fed bypassing to the downstream side of the evaporator. CONSTITUTION:A vehicle air conditioning device is constituted such that in a duct 1, provided with an inner air introducing port 2 and outside air introducing port 3 at the upstream side, an in-out air selecting door 4, blower 5, evaporator 6, air mixing door 7 and heater core 8 are successively provided to blow conditioned air from each blow port. Here a duct 9 branches from the outside air introducing port 3, and an auxiliary door 10 is provided in the upstream side of said duct 9. Further the duct 9 is communicated to the duct 1 at the downstream side of the evaporator 6 , and a blower 12 and air cleaner 13 are housed in the inside of said duct 9. Then the above described auxiliary door 10 is opened at the time of ventilation, here it is preferable to widely open the auxiliary door 10 in accordance with a number of crew members.
