Title:
REFRIGERATION CYCLE APPARATUS AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/024342
Kind Code:
A1
Abstract:
This refrigeration cycle apparatus comprises a refrigeration circuit that includes a compressor, wherein a refrigerant is sealed inside the refrigeration circuit. The refrigerant contains trifluoroiodomethane and has a global warming potential of not more than 750. The compressor is provided with a compressing mechanism unit that compresses the refrigerant and a motor that drives the compressing mechanism unit. The motor is provided with a rotor and a stator. The stator includes an insulating film made of polyester. In the refrigeration cycle apparatus, the inside of the compressor is filled with refrigerator oil. The refrigerator oil contains alkylnaphthalene as an in-oil additive.　Also provided is a compressor for use in a refrigeration cycle apparatus that is provided with a refrigeration circuit in which a refrigerant circulates, said compressor comprising: a compressing mechanism unit that compresses the refrigerant; and a motor that drives the compressing mechanism unit. The refrigerant contains trifluoroiodomethane and has a global warming potential of not more than 750. The motor is provided with a rotor and a stator. The stator includes an insulating film made of polyester. The inside of the compressor is filled with refrigerator oil. The refrigerator oil contains alkylnaphthalene as an in-oil additive.
