REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2022/018821

A1

A refrigeration cycle device comprising a refrigeration circuit that includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve, such that a refrigerant is sealed within the refrigeration circuit, the refrigerant includes trifluoroiodomethane, the compressor is filled with a refrigerator oil, and the refrigerator oil contains at least one of a first compound represented by chemical formula 1 and a second compound represented by chemical formula 2. In chemical formula 1: each of R1-R5 is a substituent configured from at least one of a carbon atom, a hydrogen atom, and an oxygen atom; and R6-R8 are substituents, at least one of which is a hydrogen atom, and the remainder of which are configured from at least one of a carbon atom, a hydrogen atom, and an oxygen atom. In chemical formula (2): R1 is a substituent that forms a ring structure with the neighboring carbon atoms, the ring structure being a 5- to 8-membered carbon ring or heterocycle; each of R2-R5 is a substituent configured from at least one of a carbon atom, a hydrogen atom, and an oxygen atom; and R6-R7 are substituents, at least one of which is a hydrogen atom, and the remainder of which are configured from at least one of a carbon atom, a hydrogen atom, and an oxygen atom.
