An air guide for a ceiling-type air conditioner is applied to the ceiling-type air conditioner comprising: an indoor unit having a heat exchanger and a blower embedded therein, and having a plurality of blowing passages for discharging, to the outside, air which has passed through the heat exchanger; a plurality of inlets for receiving the air discharged through the plurality of blowing passages; and a discharge panel having an inner space, of which at least a portion communicates with the plurality of inlets, and a ring or arc-shaped opening for discharging, into a room, air which has flowed into the inner space. The air guide includes: at least two partition parts formed in parallel to the radial direction of the opening, and dividing the inner space in the circumferential direction; and a curved part connecting the at least two partition parts, and formed in an arc shape, and is detachably inserted into the inside of the opening from the outside of the opening.

An air conditioner and a method for operating an air conditioner are provided. The air conditioner may include a case having a space formed therein and an open bottom; a panel disposed under the case and having an inlet and a plurality of outlets disposed around a circumference of the inlet; a fan disposed in the case and configured to generate an airflow from the inlet to the plurality of outlets; an airflow direction controller disposed at the plurality of outlets and configured to control an airflow direction of air flowing through the plurality of outlets in a plurality of directions; a camera disposed at one side of the panel and directed toward an indoor space; and a controller configured to control the airflow direction controller based on images corresponding to the indoor space and captured by the camera. The controller may be configured to determine an activity level of an occupant for each of a plurality of areas of the indoor space based on a plurality of images corresponding to the indoor space; determine a direction of air discharged from the plurality of outlets based on the determined activity level; and control the airflow direction controller according to the direction of the air which is determined for the plurality of outlets.

An air conditioner including a heat exchanger; a blower fan; a compressor; and a controller. The controller performs: a cooling process in which the compressor is operated to compress a circulating refrigerant, the heat exchanger performs heat exchange between the refrigerant and air, and the blowing fan is operated to blow air to the heat exchanger. The controller performs a drying process including: performing, a blowing process in which the blower fan is operated to blow air to the heat exchanger while the compressor is stopped, and performing a heating process in which the refrigerant is circulated in a direction that is changed from that of the cooling process, the blower fan is operated to blow air to the heat exchanger, and the compressor is operated to compress the refrigerant, thereby heating the surface of the heat exchanger and drying water condensed on the surface of the heat exchanger.
