Abstract

According to the present invention, even when the two-layer mode in which the inside air is introduced into a first air passage and the outside air is introduced into a second air passage is set, it is further determined whether air mix doors are controlled at the maximum hot positions. When it has been determined that the air mix doors are controlled at the maximum hot positions, the inside/outside air introduction mode is still set to the two-layer mode, because the temperature difference due to the outside air temperature is small, however, otherwise, the inside/outside air introduction mode is not set to the two-layer mode but is set to a mode in which the outside air is introduced into the both air passages. In this way, it is possible to prevent the difference between the temperatures of the air blown out from a defroster opening portion and a foot opening portion from being increased due to the temperature of the outside air.
