Abstract: A compressor includes a motor, a balance weight and a partition. The motor includes a rotor having a first end surface and a second end surface. The balance weight is disposed on the first end surface or the second end surface. The partition is disposed on the first end surface or the second end surface. The rotor has a through hole extending from the first end surface to the second end surface. The partition divides, from the through hole, at least one of a front region and a rear region. The front region is located in front of a front edge of the balance weight in a rotational direction of the rotor. The rear region is located behind a rear edge of the balance weight in the rotational direction of the rotor.

Abstract: A mold includes a first groove part and a second groove part. The first groove part extends with a constant length or a constant width from a center part to an outer circumferential part of the mold. The second groove part extends from a terminal end of the first groove part on an outer circumferential part side of the first groove part and merging with any portion of the first groove part.

Abstract: The propagation of a disproportionation reaction of a refrigerant is suppressed. Disclosed is a method that uses a composition as a refrigerant in a compressor, in which the composition includes one or more compounds selected from the group of ethylene-based fluoroolefins, 2,3,3,3-tetrafluoropropene, and 1,3,3,3-tetrafluoropropene, and the flow rate of the refrigerant flowing through a region around an ignition energy generation portion in the compressor under a predetermined high-pressure condition is greater than or equal to 1 m/s.
