Abstract: The heat cycle system of the present invention is a heat cycle system which employs a working fluid containing trifluoroethylene, comprising a compressor, a condenser, an expansion valve and an evaporator, and further having a circulation flow path and a fragile part. The circulation flow path connects the compressor, the condenser, the expansion valve and the evaporator and circulates the working fluid. The fragile part is provided in the circulation flow path or to the condenser and has a pressure resistance strength lower than the pressure resistance strength of the circulation flow path and the condenser.

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: A refrigeration cycle apparatus includes a compressor to compress a working fluid containing 1,1,2-trifluoroethylene. The compressor includes a compression unit which compresses the working fluid, a driving unit which drives the compression unit, a power supply terminal which supplies electric power from an outside of the compressor to an inside of the compressor, and a plurality of lead wires which electrically connects the driving unit to the power supply terminal. Each of the plurality of lead wires is covered with an insulating material having heat resistance of 300° C. or more at least in a part where the lead wires are bundled.
