Beschreibung
Zusammenfassung:	The mixed composition for a refrigerator of the present invention contains: a refrigerant containing at least one unsaturated fluorinated hydrocarbon compound selected from compounds represented by the following molecular formula (1): C p F r H s (1) wherein p represents an integer of from 2 to 6; r represents an integer of from 1 to 11; and s represents an integer of from 1 to 11, provided that the compound has one or more carbon-carbon unsaturated bond in a molecule, and a refrigerator lubricating oil containing, as a major component, a polyol ester (A) of a fatty acid (a1) that is a fatty acid having a number of carbon atoms of from 9 to 16 and has a content of a fatty acid having a number of carbon atoms of 9 of 50% by mol or more based on the total amount of the fatty acid (a1), and a polyol (a2) that is pentaerythritol and/or dipentaerythritol.
