<p>PROBLEM TO BE SOLVED: To mainly design a mixture area compactly and facilitate mixing of air-conditioning airs in the mixture area.SOLUTION: At least one of mode doors is formed as a halfway folding door 45 including a proximal door piece 42 that is turned with a rotation shaft 41 as a center and a distal door piece 44 connected to the distal part of the proximal door piece 42 so that the distal door piece can be halfway folded with a halfway folding point 43 as a center. The halfway folding door 45 is halfway folded, whereby the flow of at least one of heated air-conditioning air 23(H) coming through an air heating channel 26 and cooled air-conditioning air 23(C) coming through a cooling air bypass channel 27 is changed or adjusted in order to facilitate mixing of the air-conditioning airs 23.</p> |
