COMPOSITION FOR HEAT CYCLE SYSTEM, AND HEAT CYCLE SYSTEM

摘要

The present invention provides a composition for a heat cycle system, said composition being capable of replacing R410A, including a working medium for a heat cycle that has a low global warming potential, and having good lubrication properties, and provides a heat cycle system using said composition. Provided are: a composition for a heat cycle system, said composition including a heat cycle working medium that includes trifluoroethylene, and a refrigeration oil (for example, an ester-based refrigeration oil, an ether-based refrigeration oil, a polyglycol-based refrigeration oil, a hydrocarbon-based refrigeration oil); and a heat cycle system using this composition for a heat cycle system.
