Abstract:
A refrigeration lubricant composition contains an ester compound obtained from a polyol and a fatty acid, and a five- or six-membered ring cyclic ether compound having a side chain with an ester bonding. The content of the cyclic ether compound is adjusted to 0.01 to 5 parts by mass based on 100 parts by mass of the ester compound.
