Abstract

The present invention provides a refrigerating machine oil including a lubricating base oil and a compound represented by the following formula (A): wherein R a and R b each independently represent a monovalent hydrocarbon group, R c represents a divalent hydrocarbon group, X represents a polar group, and Z a and Z b each independently represent oxygen atom or sulfur atom.

Claims

exact text as granted — not AI-modified
1 . A refrigerating machine oil comprising:
 a lubricating base oil; and   a compound represented by the following formula (A):   
       
         
           
           
               
               
           
         
       
       wherein R a  and R b  each independently represent a monovalent hydrocarbon group, R c  represents a divalent hydrocarbon group, X represents a polar group, and Z a  and Z b  each independently represent oxygen atom or sulfur atom. 
     
     
         2 . The refrigerating machine oil according to  claim 1 , comprising at least one oxygen-containing oil selected from the group consisting of esters and ethers, as the lubricating base oil. 
     
     
         3 . The refrigerating machine oil according to  claim 1 , further comprising an epoxy compound. 
     
     
         4 . The refrigerating machine oil according to  claim 3 , comprising at least one selected from the group consisting of glycidyl ether-based epoxy compounds, glycidyl ester-based epoxy compounds, oxirane compounds, alkyl oxirane compounds, alicyclic epoxy compounds, epoxidized fatty acid monoesters, and epoxidized plant oils, as the epoxy compound. 
     
     
         5 . The refrigerating machine oil according to  claim 3 , comprising at least one selected from the group consisting of glycidyl ether-based epoxy compounds, glycidyl ester-based epoxy compounds, and alicyclic epoxy compounds, as the epoxy compound. 
     
     
         6 . The refrigerating machine oil according to  claim 1 , wherein the polar group has an oxygen atom.
