Abstract
In an air conditioner for a vehicle, a temperature control unit includes a first air mixing door for adjusting an opening degree of a cool air passage through which air having passed through an evaporator bypasses a heater core, and a second air mixing door for adjusting an opening degree of an air inlet portion of the heater core. At least the second air mixing door between the first and second air mixing doors is a butterfly door having a rotation shaft at a center in a door width direction. When an inside/outside air double-layer flow mode is set, the second door partitions an air passage between the evaporator and the heater core into a first air passage through which outside air flows and a second air passage through which inside air flows while fully opening the air inlet portion of the heater core. Thus, in the air conditioner, a distance between the evaporator and the heater core is reduced while partition performance between inside air and outside air due to the second air mixing door is improved.
