Abstract
A composition for a heat cycle system having less influence over the ozone layer, a low global warming potential, and excellent stability and durability is provided. A heat cycle system using the composition is also provided. The composition contains a working fluid and a phosphoric acid ester. The working fluid contains trifluoroethylene and difluoromethane. An interaction distance (Ra) between the working fluid and the phosphoric acid ester as determined from the Hansen solubility parameters is at most 15.
Claims12
A composition, comprising:
- a working fluid containing trifluoroethylene and difluoromethane, and
- a phosphoric acid ester,
- wherein an interaction distance Ra between the working fluid and the phosphoric acid ester as determined from Hansen solubility parameters of the working fluid and the phosphoric acid ester is less than 9.0.
Dependencies are inferred from the claim text.
