Abstract
Provided is a heat transfer composition comprising at least one iodocarbon compound and a refrigeration oil, and having a turbidity of 100 degrees or less as measured in accordance with JIS K0101 after stability testing. Also provided is a heat transfer composition comprising at least one iodocarbon compound and a refrigeration oil in which no hydrogen atom is bonded to a carbon atom or silicon atom in a main chain skeleton. These heat transfer compositions have significantly improved stability and are prevented from discoloration due to deterioration over time.
Claims17
(canceled)
A heat transfer composition comprising at least one C1-3 iodofluorocarbon compound and a refrigeration oil in which no hydrogen atom is bonded to a carbon atom or silicon atom in a main chain skeleton,
- wherein fluorine oil and/or silicone oil comprises 50 mass % or more based on entire base oil in the refrigeration oil.
7-8. (canceled)
A refrigeration oil for suppressing discoloration of a heat transfer composition comprising a C1-3 iodofluorocarbon compound, the refrigeration oil comprising a fluorine oil and/or silicone oil in which no hydrogen atom is bonded to a carbon atom or silicon atom in a main chain skeleton, wherein content of the fluorine oil and/or silicone oil is 50 mass % or more based on entire base oil in the refrigeration oil.
A stabilizer for a heat transfer composition comprising a C1-3 iodofluorocarbon compound, the stabilizer comprising a fluorine oil in which no hydrogen atom is bonded to a carbon atom in a main chain skeleton, wherein content of the fluorine oil is 50 mass % or more based on the stabilizer.
