Hydrocarbons are natural fluids which create less environmental effect in nature and cause less emission also. This paper emphasizes the heat-transfer performances and global warming potential of...
HFC-245fa is a common working fluid used in Organic Rankine Cycles generating mechanical power from low temperature heat. This paper compares the predicted ORC performance of two novel low GWP...
As countries phase out hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol on Substances that Deplete the Ozone Layer, they often need to make choices between high-GWP HFC alternatives...
A new analytical method using gas chromatography with an atomic emission detector (GC–AED) was developed for measurement of ambient concentrations of hydrochlorofluorocarbons (HCFCs) and...
In this study, the performances of R152a, R161, and R1234yf with very low global warming potential were investigated theoretically as alternatives to R134a in vapor compression refrigeration...
Abstract - Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (...
Abstract - Hydrocarbons are today considered as promising alternatives to hydrofluorocarbons thanks to their low environmental impact and their easy implementation. However, some precautions have...
Abstract- The equilibrium solubilities of 4-aminosalicylic acid (PAS) in supercritical carbon dioxide (SCCO2) and subcritical 1,1,1,2-tetrafluoroethane (R134a) are crucial to the process of...
Six refrigerants are evaluated as low GWP replacements for R404A using different configurations, including two-stage system architectures. These refrigerants are selected according to similar...
The visualization experiments on HFC R410A condensation in a vertical rectangular channel (14.34mm hydraulic diameter, 160mm length) were investigated. The flow patterns and heat transfer...
