Title:
AIR-CONDITIONING INDOOR UNIT
Document Type and Number:
WIPO Patent Application WO/2014/042002
Kind Code:
A1
Abstract:
An air-conditioning indoor unit (10), provided with: an indoor fan (14) capable of changing the airflow volume of blown air blown from an outlet (15); a horizontal flap (31); a Coanda flap (32); an airflow-volume controller; and an airflow direction controller. The horizontal flap (31) and the Coanda flap (32) are capable of changing the vertical airflow direction of the blown air. The airflow-volume controller controls the rotational speed of the indoor fan (14) according to the determined airflow-volume value, and thereby adjusts the airflow-volume. The airflow direction controller controls the angle of the horizontal flap (31) and the Coanda flap (32), and thereby adjusts the airflow direction. The airflow direction controller is able to switch between a first airflow direction, in which the blown air is directed at the ceiling, and a second airflow direction, in which the blown air is directed downward. The airflow-volume controller determines the airflow-volume value so as to exclude a predetermined range of low airflow volumes when the airflow direction switches from the second airflow direction to the first airflow direction.
