    摘要: Adjustable air supply diffuser (1) for diffusing an airflow (40) in a room (20), connectable to, but functionally independent of, a centralized air ventilation system (30), comprising a frame (3) fixable to a structure (21) so as to face toward the room (20); a plurality of movable fins (4) rotatably coupled to the frame (3) about respective axes that are parallel to each other; an actuator (5); a mechanism (6) coupled to any or all the fins (4) and to the actuator (5); a temperature sensor (7) configured to generate a signal (8) representative of a temperature of the air touching the sensor (7); a control unit (9) operatively connected to the temperature sensor (7), to a power source (10) and to the actuator (5), said control unit (9) being configured to power and to operate the actuator (5) as a function of the temperature signal (8) generated by the sensor (7); wherein the actuator (5), the power source (10) and the control unit (9) are embedded in the diffuser (1) and the temperature sensor (7) is connected to the frame (3) behind the fins (4) with respect to the room (20) so as to sense the temperature of the airflow crossing the diffuser (1) before the airflow (40) pass through the fins (4) and comes out from the diffuser (1) into the room (20).
    Retrofit kit (100) for an air supply diffuser (200).

    摘要: An air conditioner control method and an air conditioner. The air conditioner control method comprises: determining an operation state of an air conditioner after being powered up; when the operation state is an on state, controlling an air guide member to reset to a first reset angle, and taking the first reset angle corresponding to the air guide member as an angle after resetting; and during a rotating reset process of the air guide member, controlling the air conditioner to blow air according to a rotation angle of the air guide member. If the air guide member rotates by a corresponding angle, an air conditioner can be controlled to blow air, without waiting for the air guide member to complete resetting, so that an air blowing start time of the air conditioner is effectively shortened; after being reset, the air guide member is at a maximum opening angle; and the air guide member is controlled according to the angle after resetting to adjust an air blowing angle.
