The efficient screening of solvents for CO2 capture requires a reliable and robust equation state to characterize compare their thermophysical behavior the desired application. In this work, potentiality 14 ionic liquids (ILs) 7 deep eutectic (DESs) was examined using soft-SAFT as modeling tool these based on key process indicators, namely, cyclic working capacity, enthalpy desorption, diffusion coefficient. Once models were assessed versus experimental data, used predictive calculate...
With the current legislation on phase-out of 3rd generation refrigerants, new cooling cycles are expected to operate with 4th hence, need for optimal system performance these working fluids. In this study, an innovative optimization approach was applied design refrigerants based integrating statistical analysis experiments (DOE) molecular modeling using polar soft-SAFT model. First, a detailed multi-criteria assessment selection in medium–low temperature applications. Results demonstrated...
As the EU's mandates to phase out high-GWP refrigerants come into effect, refrigeration industry is facing a new, unexpected reality: introduction of more flammable yet environmentally compliant alternatives. This paradigm shift amplifies need for rapid, reliable screening methodology assess propensity flammability emerging fourth generation blends, offering pragmatic alternative laborious and time-intensive traditional experimental assessments. In this study, an artificial neural network...
We present here a novel integrated approach employing machine learning algorithms for predicting thermophysical properties of fluids. The allows obtaining molecular parameters to be used in the polar soft-statistical associating fluid theory (SAFT) equation state using descriptors obtained from conductor-like screening model real solvents (COSMO-RS). procedure is modeling 18 refrigerants including hydrofluorocarbons, hydrofluoroolefins, and hydrochlorofluoroolefins. training dataset included...
An urgent action to mitigate climate change is the replacement of hydrofluorocarbons used in refrigeration systems, for low-global warming potential (GWP) alternatives, with stringent legislations place.

This work presents an integrated approach rational design refrigerant blends, focused on replacing R134a (GWP 1430), and R410A 2088), automotive domestic air-conditioning, high pressure...
The use of hydrofluorocarbons (HFCs) as an alternative for refrigeration units has grown over the past decades a replacement to chlorofluorocarbons (CFCs), banned by Montreal's Protocol because their effect on depletion ozone layer. However, HFCs are known be greenhouse gases with considerable global warming potential (GWP), thousands times higher than carbon dioxide. Kigali Amendment Montreal promoted active area research toward development low GWP refrigerants replace ones in current use,...
In recent years, the commercial blend R513A (integrated by R134a and R1234yf) has been proposed to replace in air conditioning applications, given lower global warming potential of versus R134a.

This paper presents the test results obtained by TDK on newly developed metallized polymer film capacitors based 80/20 blends of polypropylene and a cyclic olefin copolymer with glass transition temperature 140°C. Polypropylene-based have been used as reference. Both showing similar frequency characteristics, blend present considerably lower leakage current perform gracefully self-healing during DC endurance tests at temperatures 120°C above.
