    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: To produce, from a composition containing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene and a substance that may cause problems in reliability and performance, 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene in which the content of the substance has been reduced. This method for producing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene comprises bringing a composition containing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene and at least one substance selected from the group consisting of water, 3,3,4,4,5,5-hexafluoro-1-pentyne, 1-chloro-3,3,4,4,5,5-hexafluoro-1-pentyne and an oxide, into contact with a solid adsorbent, to remove the substance from the composition.

    Abstract: There is provided a working fluid for heat cycle that uses (Z)-1-chloro-2,3,3,3-tetrafluoropropane (HCFO-1224yd(Z)) which has a less impact on the ozone layer, has a less impact on global warming, and has excellent cycle performance, the working fluid for heat cycle having sufficiently ensured stability and having high productivity. The working fluid for heat cycle contains HCFO-1224yd(Z) and an impurity, wherein the impurity includes a specific trace component, and a total content ratio of the trace component to a total amount of the working fluid is less than 1.5 mass %.

    Abstract: A refrigeration cycle apparatus includes a circulation path in which a working fluid containing 1,1,2-trifluoroethylene is circulated from a compressor through a condenser, an expansion valve and an evaporator back to the compressor. The refrigeration cycle apparatus includes a composition change detection unit, a composition adjustment unit, and a control unit. The composition change detection unit detects a change of a composition of the working fluid from a steady composition thereof. The composition adjustment unit adjusts the composition of the working fluid. The control unit controls the composition adjustment unit based on a detection result obtained by the composition change detection unit.
