Thermodynamic Analysis of Ozone-Safe Low Boiling Working Media for Turbo-Expander Plants

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2020
The article considers 46 low-boiling working media (LBWM) with zero potential for ozone layer destruction. Out of them, 14 ones are single-component hydrofluorocarbon refrigerants, 28 ones are multi-component mixtures of hydrofluorocarbon refrigerants ...

Hydrofluorocarbons (HFCs) in Southern China: High-Frequency Observations and Emission Estimates. [PDF]

Environ Sci Technol Lett
Hydrofluorocarbons (HFCs) are potent greenhouse gases whose global abundance continues to rise and subsequently warm the Earth. Southern China is a rapidly developing region that has experienced a sharp increase in its HFC consumption.

Electricity savings and greenhouse gas emission reductions from global phase-down of hydrofluorocarbons [PDF]

Atmospheric Chemistry and Physics, 2020
Hydrofluorocarbons (HFCs) are widely used as cooling agents in refrigeration and air conditioning, as solvents in industrial processes, as fire-extinguishing agents, for foam blowing, and as aerosol propellants. They have been used in large quantities as

Predictions of the vapor-liquid equilibrium data for low-GWP Hydrofluorocarbons + polyethylene-glycol dimethylether solvents by modified UNIFAC model [PDF]

E3S Web of Conferences, 2021
The working fluids are crucial for developing the absorption refrigeration system. Our previous work has proposed three novel working pairs, which uses the low-GWP HFCs (R32, R152a and R161) as the refrigerants and the polyethylene-glycol dimethylether ...

Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol

Nature Communications, 2019
There is great interest, in refrigeration technology, in replacing harmful volatile hydrofluorocarbons with solid materials. Here the authors show that commercially available plastic crystal neopentylglycol displays colossal and reversible barocaloric ...
