Abstract
A refrigeration cycle apparatus includes a refrigerant and a refrigeration cycle circuit. The refrigeration cycle circuit includes a heat exchanger and a compressor, and circulates the refrigerant. The refrigerant is a single hydrofluoroolefin (HFO)-based refrigerant or a mixed refrigerant. In the mixed refrigerant, an HFO-based refrigerant is mixed at a mixing ratio of 10% by weight or more. The compressor includes a motor. The motor includes a resin component. The resin component includes a polyimide having a terminal blocked with a terminal group.
Claims12
A refrigeration cycle apparatus comprising:
- a refrigerant;
- and
- a refrigeration cycle circuit including a heat exchanger and a compressor, the refrigeration cycle circuit circulating the refrigerant,
- the refrigerant being a single hydrofluoroolefin (HFO)-based refrigerant or a mixed refrigerant in which an HFO-based refrigerant is mixed at a mixing ratio of 10% by weight or more,
- the compressor including a motor including a stator core, an electric wire covered with an insulating covering, and an insulating sheet provided on the stator core, and
- at least one of the insulating covering and the insulating sheet being made of a resin material including a polyimide having a terminal blocked with a terminal group.
A compressor configured to compress a refrigerant, the compressor comprising:
- a motor including a stator core, an electric wire covered with an insulating covering, and an insulating sheet provided on the stator core,
- the refrigerant being a single HFO-based refrigerant or a mixed refrigerant in which an HFO-based refrigerant is mixed at a mixing ratio of 10% by weight or more, and
- at least one of the insulating covering and the insulating sheet being made of a resin material including a polyimide having a terminal blocked with a terminal group.
