Abstract: It is provided an ester for a refrigerator oil and of mixed alcohols and mixed monocarboxylic acids. The mixed alcohols include dipentaerythritol and tripentaerythritol in a mass ratio of 90/10 to 99.7/0.3, and the mixed monocarboxylic acids include n-pentanoic acid and 2-methyl butanoic acid in a mass ratio of 50/50 to 80/20. The ester has a kinematic viscosity of 50 to 150 mm2/s at 40° C.
