Abstract
To provide a composition for a heat cycle system, which comprises a working fluid for heat cycle which has a low global warming potential and high stability, and which can replace R410A, and a heat cycle system employing the composition. A composition for a heat cycle system, which comprises a working fluid for heat cycle containing trifluoroethylene, and a stabilizer for preventing deterioration of the working fluid for heat cycle, such as an oxidation resistance-improving agent, a heat resistance-improving agent or a metal deactivator, and a heat cycle system employing the composition for a heat cycle system.
Claims11
A composition for a heat cycle system, comprising:
- a working fluid;
- and
- a stabilizer,
- wherein:
- the working fluid comprises
- trifluoroethylene and
- trans-1,3,3,3-tetrafluoropropene,
- a total amount of the trifluoroethylene and the trans-1,3,3,3-tetrafluoropropene is 70 mass % or more based on a total mass of working fluid,
