The horizontal rotary compressor begins operation. During operation of horizontal rotary compression, the stator wires are in an atmosphere of refrigerant gas and mint lubricating oil, but the wire portion is immersed in the mixed liquid. During operation, the mixed liquid flows in from the lower end of the oil supply pipe and is supplied to the compression mechanism of the mechanical part. Further, even when the horizontal rotary compressor is stopped, the electric wire portion remains immersed in the mixed liquid.

When exposed to water, it undergoes a chemical reaction that produces acid. In addition, when refrigerant R22 is used, the hydrogen groups constituting R22 oxidize the mixed liquid, and the wires remaining in the mixed liquid are corroded by the oxidized mixed liquid, lowering the insulation resistance of the wires. There was a problem in that the safety of the rotary compressor was reduced.
