Abstract: A motor-operated compressor includes: a fixed scroll; an orbiting scroll engaged with the fixed scroll to perform an orbiting motion and forming a pair of compression chambers together with the fixed scroll during the orbiting motion; a frame provided opposite to the fixed scroll with the orbiting scroll interposed therebetween, and forming a back pressure chamber so as to axially support the orbiting scroll; and a rotation shaft coupled to the frame and the orbiting scroll in a penetrating manner. The rotation shaft is supported by the frame in a first axial direction and rotatably coupled to the fixed scroll, and an elastic member is disposed between the fixed scroll and the rotation shaft to support the rotation shaft in a second axial direction opposite to the first axial direction with respect to the first scroll.

Abstract: The present disclosure relates to a method of controlling an air conditioner. The method of controlling the air conditioner of the present disclosure includes collecting indoor unit data during a time period from when an indoor unit is ON to when the indoor unit is OFF; and correcting clusters based on changes in the clusters which are matched based on the collected data, thereby accurately determining a state of an indoor space by changing the plurality of clusters according to an environment on site.

Abstract: A motor operated compressor according to the present invention has a driving motor having a stator and a rotor. A rotation shaft of the motor is coupled to the rotor. The compressor also has a frame, a fixed scroll positioned on one side of the frame, and an orbiting scroll supported on the frame and positioned between the fixed scroll and the frame. The fixed scroll forms a compression chamber together with the orbiting scroll. The driving motor, the fixed scroll, the orbiting scroll, and the frame are positioned within a casing of the compressor. The rotation shaft rotatably passes through the fixed scroll and the frame and is to eccentrically coupled to the orbiting scroll, allowing the orbiting scroll to perform an orbiting motion relative to the fixed scroll. One end portion of the rotation shaft is supported by the fixed scroll while the other end is supported by the casing.

Abstract: The present disclosure relates to a method of controlling an air conditioner. The method of controlling the air conditioner of the present disclosure includes: collecting indoor unit data of each of a plurality of indoor units connected to an outdoor unit; controlling a total flow rate of refrigerant supplied to the plurality of indoor units based on a total load of the indoor units, which is determined based on the indoor unit data of the respective indoor units; and controlling an individual flow rate of refrigerant flowing to the respective indoor units based on clusters of the respective indoor units which are matched based on the indoor unit data of the respective indoor units.
