SAFT Equations of State for Low GWP Hydrofluoroethers Heat Transfer Fluids
Popis výsledku v původním jazyce
Three SAFT equations of state: sPC-SAFT, Soft-SAFT and SAFT-BACK were fitted to five Hydrofluoroethers (HFEs): four perfluoroalkyl methyl ethers and one C6-fluoroketone. The fits were verified with experimental data consisting of vapor pressure, liquid and vapor density and the speed of sound. Two sets of PC-SAFT parameters for HFE fluids from the literature were also tested and compared with our results. The selected fluids are good candidates to replace perfluorocarbon heat transfer fluids, and the obtained fits are intended to support the challenging transition of cooling systems to more environment-friendly fluids. The SAFT equations of state coupled with group contribution methods enable mixtures of a multitude of compounds to be modeled and their equilibrium, solubility, absorption and other effects to be predicted. This can be helpful not only when studying the properties of useful mixtures but also when evaluating material compatibility and the effects of fluid contamination, which cause a lot of concern for cooling systems that require very high reliability.
