Abstract
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.
Claims7
A heat transfer device comprising a circulation route enclosing a hydrochlorofluoroolefin (HCFO)-containing refrigerant;
- the device serving as a chiller, which cools water, and a turbo refrigerating machine;
- the device comprising an oxygen adsorption device in a region at a pressure of 1.0 MPa or less, in which the pressure is negative relative to outside of the circulation route, between an evaporator and a compressor in the circulation route;
- and
- the oxygen adsorption device being a device wherein the inside of the oxygen adsorption device is filled with an oxygen adsorption material, and oxygen is selectively adsorbed and/or absorbed and removed from a gas refrigerant when oxygen passes through the oxygen adsorption device together with the gas refrigerant.
