Abstract:
The present invention provides a lubricating oil for a compression type refrigerator including a polyvinyl ether-based compound which containing an alkylene glycol or polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a molecular weight in a range of 300 to 3,000 and one or more kinds of phosphorous compound selected from a phosphate having 25 or more carbon atoms, a phosphite having 10 to 60 carbon atoms, an amine salt of phosphate having 10 to 60 carbon atoms, and a metal salt of phosphate having to 60 carbon atoms. The lubricating oil for a compression type refrigerator of the present invention has high compatibility and high viscosity index, and is excellent in anti-seizure property and also in stability under carbon dioxide atmosphere.
