초록

The present invention provides a lubricating oil for a compression type refrigerator including a polyvinyl ether-based compound 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 a dehydrating agent. The lubricating oil for a compression type refrigerator of the present invention has high miscibility and high viscosity index, and excellent in stability without degradation and alteration due to hydrolysis under carbon dioxide atmosphere.
