A refrigerator, comprising a cooling loop. The cooling loop has a first flow path in which a compressor, a condenser, a capillary tube, and an evaporator are sequentially connected for circulating a refrigerant. The cooling loop comprises: a hot gas bypass tube, configured to form a second flow path that enables the refrigerant compressed by the compressor to flow from the compressor to the evaporator; a three-way valve, provided in the first flow path between the compressor and the condenser and connected to the hot gas bypass tube; and a two-way valve, provided in the first flow path between the condenser and the capillary tube. The three-way valve can enable the refrigerant discharged from the compressor to flow to the condenser or the hot gas bypass tube, and the two-way valve can be switched off to cut off the flow of the refrigerant discharged from the condenser.

The present invention improves the heat resistance and strength of insulation material inserted between a core and a coil of an electrical machine. A slot liner is placed between a core of an electric motor of an electric machine and a conductor of a coil. The slot liner has a multi-layer construction with an aggregate mica insulation sheet, which has excellent mechanical strength, and a peeled mica insulation sheet, which has excellent voltage resistance at high temperatures. The slot liner can include a main insulation sheet and a reinforcement sheet. The reinforcement sheet is placed between the main insulation sheet and the core at the ends of the slot.
