Refrigeration cycle device using refrigerants containing hydrocarbon and sulfur-based odorant

A refrigeration cycle device comprising:

• a refrigerant circuit comprising a compressor, wherein
• a refrigerant is enclosed in the refrigerant circuit,
• the refrigerant contains a hydrocarbon having 1 to 4 carbon atoms and a sulfur-based odorant,
• a refrigeration oil is stored in the compressor of the refrigerant circuit,
• the refrigeration oil contains a base oil,
• the base oil contains polyalkylene glycol represented by the following chemical formula 1:
• a ratio of a number of oxygen atoms to a number of carbon atoms in a molecular structure of the base oil is less than 0.50,
• wherein m and n are each a numerical value of 0 or more and represent an average of the number of ethylene oxide groups and propylene oxide groups, and R1 and R2 are a hydrogen atom or a hydrocarbon chain having one or more carbon atoms,
• m and n satisfy the following formula (1) and formula (2):
