1. Introduction. Hydrofluoro-Olefins or HFOs have been projected as the replacement for the existing HFC refrigerants. The existing HFC refrigerants such as R134a have high GWP which jeopardises its future use. The complete replacement of HFCs is a matter of concern and challenge in hand for the countries worldwide.
Michael Kauffeld – a refrigeration technology expert & Mihaela Dudita – a chemist – assess the environmental impact of HFO refrigerants & present environmental benign alternatives for the future. Despite the EU F-Gas Regulation (No. 517/2014) (or precisely because of it), refrigeration (1) system operators and manufacturers are still ...

This work proposes reference viscosity corrections that combine the Peng−Robinson (PR), Volume−Translated PR (VTPR), and Cubic−Plus−Association (CPA) Equation of State (EoS) with the friction theory (FT) model for carbon dioxide (CO 2), hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs), and their binary and ternary …
