PURPOSE:To control the rotational angle of a guide plate so that air supply toward a living area in a room be maintained in a prescribed quantity by a construction wherein the guide plate separating the direction of the air supply into the direction toward said living area and the direction toward the other area is provided rotatably at a supply opening. CONSTITUTION:When a resident turns an air-conditioning system ON and selects any one of ''weak'', ''medium'' and ''strong'' notches for quantities of airflow by means of a switch 9, a relay 10 operates according to this selection to drive a fan motor 3a. On the other hand, the relay 10 operates to close one of contacts 111, 112 and 113. Thereby one of control circuits 121, 122 and 123 for setting the rotational angle of a step motor 7 is selected and also the step motor 7 is driven. Thereby the position of a guide plate 6 is changed, and thus the speed of airflow around the resident in a living area does not increase almost at all even when the quantity of air supply is increased. |
