Disclosed are a ceiling recessed fan, a control method and control apparatus thereof, and a recessed air conditioner, wherein the ceiling recessed fan comprises a main body frame (1a) and an air outlet assembly (3a). An air outlet duct (2a) is disposed in the main body frame (1a), the air outlet duct (2a) having a first end (21a) and a second end (22a) provided along the direction of airflow; the air outlet assembly (3a) is arranged in the main body frame (1a) in a way so as to be able to be raised and lowered. The ceiling recessed fan provided in the embodiments of the present disclosure, when in a cooling mode, limits the ratio of the height of an air outlet (10a) to the width of the first end (21a) of the air outlet duct (2a); that is, design standards are defined for the ceiling recessed fan so as to balance the attenuation of the air supply distance and the air output volume of the ceiling recessed fan, such that the produced air output effect of the ceiling recessed fan satisfies requirements when in a
