Document Type and Number:
WIPO Patent Application WO/2018/169039
Kind Code:
A1
Abstract:
Provided are a composition for a heat cycle system with which it is possible to more stably lubricate HCFO and CFO, and a heat cycle system in which said composition is used. A composition for a heat cycle system that includes a heat cycle working medium including at least one compound selected from prescribed HCFO and CFO, and a mixed refrigerating machine oil obtained by mixing a naphthenic mineral oil and another prescribed refrigerating machine oil, the composition for a heat cycle system being such that the kinematic viscosity at 40°C of the mixed refrigerating machine oil is 300 mm2/s or lower, the viscosity at 60°C of a mixed composition 1 of a heat cycle working medium having a heat cycle working medium concentration of 10% by mass and the mixed refrigerating machine oil is 10 mPa∙s or higher, and the two-phase separation temperature of a mixed composition 2 of a heat cycle working medium having a mixed refrigerating machine oil concentration of 5% by mass and a mixed refrigerating machine oil is 0°C or lower; and a heat cycle system in which this composition for a heat cycle system is used.
