Refrigeration cycle apparatus

A refrigeration cycle apparatus comprising:

• a refrigeration circuit, the refrigeration circuit including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve, wherein
• a refrigerant is sealed within the refrigeration circuit,
• the refrigerant contains trifluoroiodomethane,
• the compressor is filled with a refrigerator oil,
• the refrigerator oil contains at least one of a first compound represented by the following chemical formula 1 and a second compound represented by the following chemical formula 2:
• in the chemical formula 1,
• each of R1 to R5 is a substituent composed of at least one of carbon atom, hydrogen atom, and oxygen atom, and
• at least one of R6 to R8 is a hydrogen atom with the remainder being a substituent composed of at least one of carbon atom, hydrogen atom, and oxygen atom, and
• in the chemical formula 2,
• R1 is a substituent forming a ring structure with neighboring carbon atoms,
• the ring structure is a 5- to 8-membered carbon ring or heterocyclic ring,
• each of R2 to R5 is a substituent composed of at least one of carbon atom, hydrogen atom, and oxygen atom, and
• at least one of R6 to R7 is a hydrogen atom with the remainder being a substituent composed of at least one of carbon atom, hydrogen atom, and oxygen atom.
