Abstract:
An air-mixing air-conditioning system controlling a temperature of air blown into a vehicle interior after mixing a first air stream and a second air stream which differ in temperature, the system comprising:an air mixing chamber having a first air inlet opening at which the first air stream is introduced, a second air inlet opening which opens in a direction intersecting the first air inlet opening for introduction of the second air stream, and an outlet opening at which the first air stream introduced through the first air inlet opening and the second air stream introduced through the second air inlet opening flow out; and guide walls dividing the first and second air inlet openings into a plurality of sections and extending in a direction parallel with the air flow; wherein the air mixing chamber is configured such that at least one of the first and second air streams hits against an inside wall of the air mixing chamber, flowing toward the outlet opening side after changing the direction of its flow; wherein, as viewed from the outlet opening, a guidance wall that guides a non-hitting air stream is established along an imaginary line extending from a guidance wall that guides a hitting air stream to the inner wall of the air mixing chamber, so that when the first and the second air streams are led to the guidance walls, respectively, and flow to the air mixing chamber, air stratums of the first and the second air streams are alternately produced therein; and wherein a guide length a1 of a first one of the guide wall that guides a hitting air stream hitting against an inside wall of the air mixing chamber is set from 0.05 times or more to 0.5 times less than a length L1 from one of the inlet openings for introducing the hitting air stream to the inside wall of the air mixing chamber against which the hitting air stream hits.
