Document Type and Number:
WIPO Patent Application WO/2018/072216
Kind Code:
A1
Abstract:
A humidifying and fresh air exchange indoor unit of an air conditioner, comprising a cross-flow impeller air outlet passage (15) and a cross-flow impeller air outlet passage wall (14). An air induction opening (9) is provided on the cross-flow impeller air outlet passage wall (14); the clockwise included angle between the projection line, in a projection plane which is perpendicular to the axis of the cross-flow impeller of the indoor unit and makes an air outlet (16) of the indoor unit be located on the lower left side, of the air induction opening (9) and the segment in the positive direction of a tangent of the air outlet passage wall, with the point of intersection of the air induction opening (9) and the cross-flow impeller air outlet passage wall (14) as an upper tangent point (A), is greater than or equal to 15 degrees and smaller than or equal to 180 degrees; a water discharge pipe (11) of the indoor unit is connected to an air induction pipe (7), and the other port of the air induction pipe (7) is connected to the air induction opening (9) formed on the cross-flow impeller air outlet passage wall (14) in a penetrating mode. The indoor unit has advantages of introducing outdoor air, humidifying and exchanging indoor air, and recycling the refrigerating capacity, thereby saving energy and increasing the outlet air temperature and the air volume of the indoor unit.
