Abstract: Disclosed is a control method of an air conditioner system including: when a preset reception rate degradation error occurs in one or more indoor unit, transmitting a channel switch request signal to an outdoor unit belonging to the particular group; performing a channel scan by each of the outdoor unit and the plurality of indoor units; transmitting, by the plurality of indoor units, channel scan results to the outdoor unit; determining, by the outdoor unit, a channel for use of the particular group based on a result of a channel scan performed by the outdoor unit and the channel scan results received from the plurality of indoor units; and outputting, by the outdoor unit, information on the determined channel to the plurality of indoor units. Accordingly, it is possible to change to a good communication channel according to change in a communication environment.

Abstract: A mutual rotating scroll compressor is provide. The mutual rotating scroll compressor includes: a first frame (31) fixed to a casing; a second frame (32) provided with an interval between the first frame and the second frame, a compression space (30a) being provided between the first frame and the second frame; a first scroll (33) rotatably supported by the first frame and coupled to a driving motor (20) to rotate in the compression space; a second scroll (34) engaged with the first scroll to rotate about the second frame, the second scroll and the first scroll forming a compression chamber (V) in the compression space; and a bearing housing (37) including a housing part (371), including a boss accommodation part (372) to which the second scroll is rotatably coupled, and a hinge lug (375) which extends from the housing part and is movably coupled to the second frame. In the bearing housing, a third center which is a center of the hinge lug in an axial direction is provided on a plane and is eccentric with respect to a second center which is a center of the boss accommodation part in an axial direction, and each of the second center and the third center is provided on a plane and are eccentric with respect to a first center of the first scroll in an axial direction.
