Abstract: A method of controlling a ceiling type air conditioner including a panel located on a ceiling surface, outlets formed at positions corresponding to four sides of the panel, a first vane group for opening and closing the outlets located at two opposing sides, and a second vane group for opening and closing the outlets located at the other two opposing sides includes performing a dynamic airflow mode in which an indoor temperature reaches a set temperature by controlling rotation angles of the first vane group and the second vane group, and calculating a pleasant airflow index Y for determining a pleasant feeling of a user at the set temperature. The pleasant airflow index is calculated using the indoor temperature, the rotation angle of the first vane group or the second vane group, an air volume, a distance from a floor surface and an airflow position as variables.

Abstract: According to the present disclosure, it is determined whether or not the room is heated according to a temperature difference between a room temperature Tp and a set temperature Ts, and even when there is little or no heating load due to the temperature difference between the room temperature Tp and the set temperature Ts, the floor heating is performed by determining a temperature difference between the room temperature Tp and a floor temperature Tb.

Abstract: A method of controlling a ceiling type air conditioner including a panel located on a ceiling surface, outlets formed to correspond to four sides of the panel, and first to fourth discharge vanes for opening and closing the outlets, and each of the first to fourth discharge vanes including an upper discharge vane and a lower discharge vane located below the upper discharge vane and rotating along with the upper discharge vane includes performing first operation, performing second operation, performing third operation, and performing fourth operation in which the first discharge vane rotates in the second angle group, the second discharge vane rotates in the third angle group, the third discharge vane rotates in the fourth angle group and the fourth discharge vane rotates in the first angle group. The first to the fourth angle groups are set such that rotation angles of the discharge vanes have different ranges.

Abstract: A method of controlling a ceiling type air conditioner including a panel, a first vane group, and a second vane group, and each of the first and second vane groups including an upper discharge vane and a lower discharge vane includes performing first mixing operation in which the first vane group guides air in a direction close to the ceiling surface to form horizontal airflow and the second vane group guides air in a direction close to a floor surface to form vertical airflow, determining whether swing operation of continuously rotating the first vane group and the second vane group or fixing operation in which the first vane group and the second vane group are located at the same angle is performed, and performing second mixing operation in which the first vane group forms the vertical airflow and the second vane group forms the horizontal airflow.

Abstract: An air conditioner and a method for controlling an air conditioner are provided. The method may include acquiring a top view image for an indoor space using an imaging device and calculating a height of a ceiling in which an indoor device may be mounted; determining whether an image is a human body or an obstacle, with respect to at least one image included in the to view image; and performing control of the indoor device to allow air flow to avoid an obstacle and be discharged toward a human body by controlling driving of an indoor fan or one or more discharge vane provided in the indoor device.

Abstract: An air conditioner and a control method thereof are provided. The air conditioner includes a sensor portion including at least one sensor, a controller including at least one control portion to control a function of the air conditioner, and at least one processor operatively connected to the sensor and the controller. The at least one processor is configured to obtain an airflow speed and indoor environmental data by the sensor portion while the air conditioner is operating, generate a first algorithm by applying the obtained airflow speed, the indoor environmental data, and pre-stored reference data to a second algorithm, and control operation of the air conditioner based on the generated first algorithm.
