Air-distribution device based on the Coanda effect with means for imparting a circulatory motion on the flow of air not properly oriented

摘要

Described herein is a Coanda-effect air distributor for distributing a flow between a number of ducts set downstream. Provided in the area that separates the initial ends of two ducts set downstream is the inlet of a recirculation duct that creates an air circulation that masks the entrance of a duct set downstream when the flow is deviated into the other duct.
