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 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, having a circulation path in which a working fluid for heat cycle containing trifluoroethylene is circulated from a compressor via a condenser, an expansion valve and an evaporator to the compressor, 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.

Abstract: To provide a method for producing an aqueous liquid containing a vinyl polymer, of which the production efficiency is high, without lowering the yield of the vinyl polymer. When removing a hydrophilic organic solvent from a mixed liquid comprising a vinyl polymer, the hydrophilic organic solvent and water to produce an aqueous liquid containing the vinyl polymer, a liquid phase and a gas phase are formed in a closed container, a part of the liquid of the liquid phase is formed into small droplets and brought into contact with the gas phase to vaporize the hydrophilic organic solvent, and the vaporized hydrophilic organic solvent is removed from the closed container. Specifically, for example, a closed container 10 having a liquid inlet 22, a gas outlet 30, a liquid outlet 21, a liquid inlet 22 and a liquid outlet 21 which are connected and having an external circulating system provided with means to control the temperature and the pressure of liquid, is filled with a mixed liquid 40 to form a liquid phase 50 and a gas phase 51, the mixed liquid 40 of the liquid phase 50 is circulated from the liquid outlet 21 to the external circulating system 20, and the temperature and the pressure of the mixed liquid 41 in the external circulating system 20 are controlled to conditions such that the hydrophilic organic solvent is easily vaporized in liquid droplets in the gas phase 51, followed by discharging the mixed liquid 41 in the form of the small droplets from the liquid inlet 22 to the gas phase 51 and draining the gas in the gas phase 51 from the gas outlet 30.
