Title:
REFRIGERATOR LUBRICATING OIL AND MIXED COMPOSITION FOR REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2016/158615
Kind Code:
A1
Abstract:
This mixed composition for a refrigerator includes: a refrigerant that includes at least one type of unsaturated fluorohydrocarbon compound selected from among compounds represented by molecular formula (1) [(1) CpFpHs, wherein p is an integer from 2 to 6, r is an integer from 1 to 11, s is an integer from 1 to 11, and the molecule has one or more unsaturated carbon-carbon bond]; and a refrigerator lubricating oil that contains, as the main component thereof, a polyoxyalkylene glycol compound represented by general formula (2) [(2) R1-[(OR2)m-OR3]n, wherein R1 is selected from among a hydrogen atom, C1-C10 alkyl groups, C2-C10 acyl groups, C1-C10 aliphatic hydrocarbon groups that have 2-6 bonding sites, and C3-C15 substituted groups that include a heterocycle that includes oxygen and/or sulfur as a heteroatom, R2 is a C2-C4 alkylene group, R3 is a hydrogen atom, a C1-C10 alkyl group, or a C2-C10 acyl group, n is an integer from 1 to 6, and m is a number that makes the average value of m∙n 6-80] and that, based on the total amount of the refrigerator lubricating oil, includes 1.0 mass% or more of a phenothiazine compound. The present invention can provide a mixed composition that is for a refrigerator and that presents little risk of igniting in high-temperature environments, even if the mixed composition were to leak out of a refrigerator that uses refrigerant that includes a slightly flammable refrigerant. The present invention can also provide a refrigerator lubricating oil that can be applied to the mixed compound for a refrigerator.
