Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/198150
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an air conditioner with which the blowing efficiency of a centrifugal fan can be improved. This air conditioner is provided with: a centrifugal fan; a heat exchanger disposed so as to surround the outer circumference of the centrifugal fan; a first partition wall that separates a suctioning-side region and a blowing-side region of the centrifugal fan; and a second partition wall that extends from the first partition wall toward the centrifugal fan, wherein the second partition wall has a second end part which is the end part on the centrifugal fan side. When assuming that a first distance is the distance in the radial direction between the outer circumferential edge of the centrifugal fan and the second end part, a second distance is the distance between the outer circumferential edge and the heat exchanger, a first radial cross-section is the radial cross-section that passes through a rotating shaft and is parallel to the rotating shaft, and a second radial cross-section is the radial cross-section in which the second distance is longer than the second distance in the first radial cross-section, the first distance in the second radial cross-section is longer than the first distance in the first radial cross-section.
