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.
