    摘要： The disclosed technology relates to a heat transfer fluid and a heat transfer system and heat transfer method employing the heat transfer fluid. In particular, the technology relates to a heat transfer fluid with low electrical conductivity, low flammability, and low freeze point that provides excellent peak temperature reduction in a heat transfer system, such as that for cooling a power system of an electric vehicle or computer electronics.

    摘要： The position of the stabilizer container 7 in the circulation route is not limited. The stabilizer container 7 is preferably disposed between the evaporator and the condenser between which the refrigerant flows in the circulation route as a liquid refrigerant. Specifically, the stabilizer container 7 is preferably disposed between the outdoor heat exchanger 4 and the expansion mechanism 5 or between the indoor heat exchanger 6 and the expansion mechanism 5. During cooling, the outdoor heat exchanger 4 functions as a condenser and the indoor heat exchanger 6 functions as an evaporator. During heating, the outdoor heat exchanger 4 functions as an evaporator and the indoor heat exchanger 6 functions as a condenser. In either case of cooling or heating, the liquid refrigerant is present between the expansion mechanism 5 and the outdoor heat exchanger 4 or between the expansion mechanism 5 and the indoor heat exchanger 6 depending on the refrigerant circulation direction, and the stabilizer container 7 is located where the liquid refrigerant is present (i.e., between the expansion mechanism and whichever heat exchanger 4, 6 serves as the evaporator in the refrigerant circulation direction). Thus, as the liquid refrigerant passes through the stabilizer container 7, oxidation of the refrigerant can be efficiently prevented and acids in the circulation route can be efficiently scavenged.

    摘要： The present invention provides a composition comprising an HFO compound, the composition having excellent stability with decomposition and oxidation of the HFO compound being inhibited, the composition having improved refrigerating capacity when used as a heat transfer medium, compared with the case in which an HFO compound is used alone. More specifically, the present invention provides a composition comprising at least one HFO compound selected from the group consisting of HFO-1234yf, (E-/Z-)HFO-1234ze, and (E-/Z-)HFO-1225ye; and a chlorine-containing compound, wherein (1) the chlorine-containing compound is at least one member selected from the group consisting of CH2=CHCl, CHF=CHCl, CH2=CFCl, CF3Cl, CH3Cl, CF3CH2Cl, CClF=CHCl, and CHF=CCl2, and (2) the chlorine-containing compound is contained in an amount ranging from 1 to 500000 mass ppm.
