Compressed Liquid Density Measurements for 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf)

Journal of Chemical & Engineering Data, 2011
A total of 13 796 compressed liquid density measurements for 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) for eight isotherms evenly spaced from (283.15 to 353.15) K for pressures from near saturation to 35 MPa are presented. In addition, a saturated liquid density correlation and a Tait correlation are developed.

Isothermal Vapor–Liquid Equilibria of the Absorption Working Pairs (R1234yf + NMP, R1234yf + DMETrEG) at Temperatures from 293.15 K to 353.15 K

Journal of Chemical & Engineering Data, 2018
The vapor–liquid equilibria (VLE) data of R1234yf + NMP and R1234yf + DMETrEG were measured at the temperature range of 293.15–353.15 K in a dual cycle experimental apparatus. The thermodynamic consistency of the VLE data was checked with an area test. The VLE data were correlated by the nonrandom two-liquid model, and the results showed that they had ...

Performance characteristics of R1234yf ejector-expansion refrigeration cycle

Applied Energy, 2014
Abstract With a constant-pressure mixing ejector, the performance characteristics of an ejector-expansion refrigeration cycle (EERC) using R1234yf as refrigerant have been investigated. Also, the performance of R1234yf and R134a in the EERC has been compared. The study shows that, at condensing temperature of 40 °C and evaporation temperature of 5 °C,

Thermodynamic Analysis of a Refrigeration System Operating with R1234yf Refrigerant

2018
After restriction of European Union on using high-GWP refrigerants, the investigations have been directed to utilize low-GWP refrigerants in available systems to determine the suitability of their operating conditions. In this study, energy and exergy parameters were investigated as a result of using R1234yf in a refrigeration system originally ...

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 ...
