Energy, Exergy, and Environmental (3E) Analysis of Hydrocarbons as Low GWP Alternatives to R134a in Vapor Compression Refrigeration Configurations
MDPI (2021-07-05)The phase-down of hydrofluorocarbons and substitution with low global warming potential values are consequences of the awareness about the environmental impacts of greenhouse gases. This theoretical study evaluated the ... -
Optimal refrigerant mixture in single-stage high-temperature heat pumps based on a multiparameter evaluation
Elsevier Ltd (2022-01-25)High-temperature heat pumps (HTHPs) are compression systems that convert residual heat to high-grade heat used in several industrial applications. Refrigerants for HTHPs are still not explored, and most studies consider ... -
Predictions of European refrigerants place on the market following F-gas regulation restrictions
Elsevier (2021-03-10)The European Union (EU) Regulation on fluorinated greenhouse gases (F-gases) has encouraged to reduce gradually the number of hydrofluorocarbons (HFC) that can be placed on the market (POM) to 21% of the baseline level in ... -
Thermodynamic evaluation of CO2 for ultra-low temperature refrigeration
Elsevier (2023-09-12)Carbon dioxide (CO2, R744) is the only refrigerant in the safest class by the ASHRAE 34 Standard in the group of natural refrigerants, with zero ozone depletion potential and a global warming potential of 1. It has been ...
