Removal of R134a from air/R134a mixture based on cryogenic condensation method

2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021
The emission of greenhouse gases is aggravating the global warming. Nowadays, R134a is widely used in refrigeration engineering, and its globe warming potential (GWP) is relatively high (1301). So, it is imperative to recover the R134a in refrigerating devices, and prevent it from being released to the atmosphere.

Thermal conductivity of R134a

Fluid Phase Equilibria, 1992
Abstract Thermal conductivity measurements are reported for the alternative refrigerant 1,1,1,2-tetrafluoroethane (R134a). These measurements were made over the temperature range from 200 to 390 K at pressures to 70 MPa. Data are reported for the liquid, vapor, and supercritical fluid phases.

Experimental study on R1234yf/R134a mixture (R513A) as R134a replacement in a domestic refrigerator

Applied Thermal Engineering, 2019
Abstract In this paper, a comparative experimental study between R134a and its low GWP alternative R1234yf/R134a (called R513A, 44/56% weight) in a domestic refrigerator was presented. Three kinds of tests were carried out under the same ambient condition. The optimal charge for R513A is 80 g, which is 5.9% lower than that of R134a (85 g).
