Abstract: To provide a fluid composition and a refrigerant composition having flammability suppressed; and an air conditioner in which restrictions in order to inhibit combustion of the refrigerant composition are reduced and it is thereby possible to omit or simplify measures for inhibiting combustion of the refrigerant composition. The fluid composition is either a composition (I) comprising at least one component (A) selected from the group consisting of alkanes, halogenated alkanes and alkenes and at least one component (B) selected from halogenated alkenes, or a composition (II) (excluding the composition (I)) comprising two or more ingredients (B) selected from halogenated alkenes. The fluid composition has a combustion inhibiting effect as defined by −100×{(measured maximum burning velocity)−(estimated maximum burning velocity)}/(estimated maximum burning velocity), of at least 10%.

Abstract: To provide a heat cycle system with high durability, which employs a working fluid for heat cycle containing trifluoroethylene having a low global warming potential.A heat cycle system 10, comprising a circulation path in which a working fluid for heat cycle containing trifluoroethylene is circulated from a compressor 11 via a condenser 12, an expansion valve 13 and an evaporator 14 to the compressor 11, wherein the compressor has in its electrical circuit a current-limiting apparatus capable of limiting the current within 6 milliseconds after the heat cycle system enters into an abnormal operation state.
