ROTARY COMPRESSOR, CONTROL METHOD THEREOF, AND AIR CONDITIONER USING THE SAME

PROBLEM TO BE SOLVED: To provide a rotary compressor and a control method thereof capable of inhibiting temperature rise of a cylinder due to partial load operation and improving partial load efficiency of the compressor, and an air conditioner using the same. SOLUTION: A rotary compressor includes a cylinder to form a first compressing chamber and a second compressing chamber partitioned from each other and including a first vane slot and a second vane slot which are formed in the first compressing chamber and the second compressing chamber, respectively, and a first roller and a second roller to respectively rotate in the first compressing chamber and the second compressing chamber to compress compressing media, the rotary compressor operating in a full load running mode in which a load running is concurrently performed in the first compressing chamber and the second compressing chamber, and in a partial load running mode in which a load running is performed in only the second compressing chamber, and the rotary compressor further includes a first vane which is accommodated movably in and out of the first vane slot, a vane driving part to enable the first vane to contact and be distanced apart from an outer surface of the first roller to perform a load running and a no-load running in the first compressing chamber, and a controller to control the vane driving part to intermittently perform the load running in the first compressing chamber in the partial load running mode.
