ABSTRACT:
An air-conditioning apparatus for adjusting the direction and quantity of air comprises a duct device forming an air passage passing through the duct device, and an airflow adjusting device. The airflow adjusting device is made from a single thin plate and fitted to the duct device across the air passage to adjust a flow of air. Slits of predetermined patterns are formed on the airflow adjusting device to define a plurality of vanes which are integral to the airflow adjusting device. Functions for adjusting the direction and quantity of air are basically realized only with the single thin plate so that the material and manufacturing costs of the apparatus will be reduced, the transportation, installation and maintenance of the apparatus simplified, and angles of the vanes adjusted separately and freely.
