Evaporation of R1234yf, R1234ze(E) and R1234ze(Z) on Cu surface: A molecular dynamics study

Journal of Molecular Liquids, 2021
Abstract Understanding the interface phase transition behavior of the working fluid helps to improve the energy conversion efficiency of a thermodynamic cycle. In this study, the evaporation behaviors of R1234yf, R1234ze(E) and R1234ze(Z) liquid film on the solid surface are performed using molecular dynamics simulation.

Hazard evaluation of R32/R1234ze(E) cloud explosion

International Journal of Refrigeration, 2020
Abstract This paper is aimed at evaluating characteristics of R32/R1234ze(E) cloud explosion. The flame morphologies and explosion pressure are obtained experimentally and the laminar burning velocity is analyzed thermally and chemically. The results indicated that with the increase of equivalence ratio, the limiting oxygen content of xE=10 ...

Low GWP refrigerants R1234ze(E) and R1234ze(Z) for high temperature heat pumps

International Journal of Refrigeration, 2014
Abstract Low global warming potential refrigerants R1234ze(E) and R1234ze(Z) are anticipated to be the refrigerants of choice for high-temperature heat pump systems in industrial applications. Their thermodynamic attributes are thermodynamically, experimentally, and numerically assessed in this study.

pVTx properties of binary R1234ze(E)/R600a system

The Journal of Chemical Thermodynamics, 2017
Abstract The gaseous pVTx properties of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) + 2-methylpropane (R600a) mixtures were measured in temperatures from 280.15 to 330.15 K and corresponding pressures from 138 to 930 kPa and the compositions of R1234ze(E) from 0.65 to 0.90 mass fraction using the Burnett isothermal expansion method.

Solid–liquid equilibria for the R32 + R1234ze(E) binary system

International Journal of Refrigeration, 2019
Abstract In this paper, the solid – liquid equilibrium of the binary system containing difluoromethane (R32) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) was experimentally evaluated. An experimental setup was used to measure 20 different compositions of the binary system in the temperature range from 168.2 K to 132.00 K.

Measurements of Surface Tension of R1234yf and R1234ze(E)

Journal of Chemical & Engineering Data, 2017
An experimental apparatus based on the differential capillary rise method for measuring the surface tension was built up and verified. The surface tensions of R1234yf and R1234ze(E) were measured from 242 to 365 K and 242 to 380 K, respectively. The surface tension data were correlated as a function of temperature, and the average absolute deviations ...

Heat transfer during evaporation of R1234ze(E), R32, R410A and a mixture of R1234ze(E) and R32 inside a horizontal smooth tube

International Journal of Refrigeration, 2013
Abstract This experimental study measured and compared the heat transfer coefficients during in-tube evaporation of R1234ze(E), R32, the nearly azeotropic HFC refrigerant blend R410A and a zeotropic mixture R1234ze(E)/R32 (55/45 mass %) inside a water heated double tube heat exchanger.
