Air-conditioning apparatus for supplying e.g. cool air to inner space of motor car, has diffuser channel provided with large expansion at diffuser inlet in direction parallel to fictitious plane stretched from element

摘要

#CMT# #/CMT# The apparatus has a blower (1) i.e. radial blower, provided with a blower inlet port for sucking air. An air conditioning element (6) e.g. air filter, is utilized for conditioning air flowing through the apparatus. A diffuser channel directs air from a blower exhaust opening to the air conditioning element. The diffuser channel is provided with a large expansion at a diffuser inlet in a direction parallel to a fictitious plane stretched from the element, where the expansion is larger than that in an inlet side of the element in a direction. #CMT#USE : #/CMT# Air-conditioning apparatus for supplying cool air and/or hot air to the inner space of a motor car. #CMT#ADVANTAGE : #/CMT# The diffuser channel is provided with the large expansion at a diffuser inlet in a direction parallel to a fictitious plane stretched from the element, and the expansion is larger than that in the inlet side of the element in the direction, thus reducing air flow from the diffuser inlet, and reducing pressure drop within the element, and hence achieving better and uniform flow of air through the air conditioning element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a blower, a diffuser channel and an element. 1 : Blower 2 : Blower housing 6 : Air conditioning element 11 : Diffuser channel housing.
