Method of controlling vanes of ceiling type air conditioner

Abstract

A method of controlling a ceiling type air conditioner to rapidly generate uniform airflow in a room is disclosed. The method includes the steps of controlling the angle of the vanes to be a predetermined maximum angle to increase the airflow to a maximum airflow when initiating the ceiling type air conditioner, and decreasing the angle of the vanes from the maximum angle to a predetermined minimum angle step by step by a predetermined time interval to adjust the airflow. The airflow with the maximum rate can be supplied when initiating the air conditioner such that the chilled/heated airflow rapidly reaches the floor to improve the satisfaction of people in the indoor region. The rate of the airflow varies as time passes so that the uniform airflow can be rapidly supplied and the air conditioning efficiency can be improved.
