The position of the stabilizer containerin the circulation route is not limited. The stabilizer containeris preferably disposed between the evaporator and the condenser between which the refrigerant flows in the circulation route as a liquid refrigerant. Specifically, the stabilizer containeris preferably disposed between the outdoor heat exchangerand the expansion mechanismor between the indoor heat exchangerand the expansion mechanism. During cooling, the outdoor heat exchangerfunctions as a condenser and the indoor heat exchangerfunctions as an evaporator. During heating, the outdoor heat exchangerfunctions as an evaporator and the indoor heat exchangerfunctions as a condenser. In either case of cooling or heating, the liquid refrigerant is present between the expansion mechanismand the outdoor heat exchangeror between the expansion mechanismand the indoor heat exchangerdepending on the refrigerant circulation direction, and the stabilizer containeris located where the liquid refrigerant is present (i.e., between the expansion mechanism and whichever heat exchangerserves as the evaporator in the refrigerant circulation direction). Thus, as the liquid refrigerant passes through the stabilizer container, oxidation of the refrigerant can be efficiently prevented and acids in the circulation route can be efficiently scavenged.

Heat transport device and heat transport method using same

A heat transfer device that contains a circulation route enclosing a refrigerant containing a hydrohaloolefin, the heat transfer device being capable of reducing the influence of oxygen entrapped in the circulation route; and a heat transfer method using the heat transfer device. Also, a heat transfer device that contains a circulation route enclosing a refrigerant containing at least one member selected from the group consisting of hydrofluoroolefins (HFOs), hydrochlorofluoroolefins (HCFOs), and hydrochloroolefins (HCOs); and the device containing an oxygen adsorption device between an evaporator and a compressor present in the circulation route; and a heat transfer method using the same.
