Abstract
Official abstract text for this publication.
A working fluid composition for a refrigerating machine comprising: a refrigerating machine oil containing at least one lubricating base oil selected from a mineral oil and a synthetic oil, and at least one phosphorus compound selected from a mono(alkylphenyl) diphenyl phosphate having a C3-C5 alkyl group and a di(alkylphenyl) phenyl phosphate having two C3-C5 alkyl groups, wherein a content of the phosphorus compound is 0.01 to 5% by mass based on a total amount of the refrigerating machine oil; and a hydrocarbon refrigerant having 2 to 4 carbon atoms.
First claim
Opening claim text (preview).
The invention claimed is: 1. A working fluid composition for a refrigerating machine comprising: a refrigerating machine oil comprising at least one lubricating base oil selected from a mineral oil and a synthetic oil, and at least one phosphorus compound selected from a mono(alkylphenyl) diphenyl phosphate having a C3-C5 alkyl group and a di(alkylphenyl) phenyl phosphate having two C3-C5 alkyl groups, wherein a content of the phosphorus compound is 0.01 to 5% by mass based on a total amount of the refrigerating machine oil; and a hydrocarbon refrigerant having 2 to 4 carbon atoms. 2. The working fluid composition for a refrigerating machine according to claim 1 , wherein the phosphorus compound is at least one selected from a mono(butylphenyl) diphenyl phosphate having a C4 alkyl group and a di(butylphenyl) phenyl phosphate having two C4 alkyl groups. 3. The working fluid composition for a refrigerating machine according to claim 1 , wherein the lubricating base oil has a kinematic viscosity at 40° C. of 3 to 500 mm 2 /s and is at least one selected from a mineral oil, an alkylbenzene, a poly-α-olefin, an ester, and an ether. 4. The working fluid composition for a refrigerating machine according to claim 1 , wherein the lubricating base oil has a kinematic viscosity at 40° C. of 3 to 300 mm 2 /s and is at least one selected from a mineral oil, an alkyl benzene, a poly-α-olefin, a diester, a polyol ester, a complex ester, a polyalkylene glycol, a polyalkylene glycol compound, and a polyvinyl ether. 5. The working fluid composition for a refrigerating machine according to claim 1 , wherein the hydrocarbon refrigerant is at least one selected from propane, propylene, normal-butane and isobutane. 6. A refrigerating machine oil comprising: at least one lubricating base oil selected from a mineral oil and a synthetic oil; and at least one phosphorus compound selected from a mono(alkylphenyl) diphenyl phosphate having a C3-C5 alkyl group and a di(alkylphenyl) phenyl phosphate having two C3-C5 alkyl groups, wherein a content of the phosphorus compound is 0.01 to 5% by mass based on a total amount of the refrigerating machine oil, the refrigerating machine oil being used together with a hydrocarbon refrigerant having 2 to 4 carbon atoms.
