Abstract
In an air conditioning apparatus for a vehicle, a first cool air bypass passage is provided at an upper side of a heater core, and a second cool air bypass passage is provided at a lower side of the heater core. Cool air from the first cool air bypass passage and warm air having passed through the heater core are mixed in a first air mixing chamber, and a ratio between an amount of cool air and an amount of warm air is adjusted by an air mixing film member. Further, cool air from the second cool air bypass passage and warm air from the heater core are mixed in a second air mixing chamber, a ratio between an amount of cool air and an amount of warm air is adjusted by an air mixing door, and the second air mixing chamber is provided at an immediately downstream air side of the heater core. Thus, in the air conditioning apparatus, a pressure loss in a ventilation system can be reduced.
