“…In this work, the ( p , ρ, T ) behavior and saturated densities of a blend of R1234yf/290 mixtures were measured at temperatures higher than the data sets of Zhong et al. − The critical parameters were determined from the saturated densities near the critical point. The data obtained in this work revealed that the Zhong model is less accurate in the regions away from their experimental data and that the model sometimes shows numerical instability in the critical region.…”

“…The data obtained in this work revealed that the Zhong model is less accurate in the regions away from their experimental data and that the model sometimes shows numerical instability in the critical region. This work formulated a new mixture model by fitting the experimental data of this work and those of Zhong et al − The mixture model represents the data used in the fitting almost within their experimental uncertainties. In addition, the mixture model provides numerical stability over wide ranges of temperature and pressure, and therefore, it can also be applied to extrapolated regions outside the fitted experimental data.…”

Thermodynamic Properties of 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) and Propane (R290) Mixtures: (p, ρ, T) Behavior, Saturated Liquid and Vapor Densities, Critical Parameters, and a Mixture Model

The (p, ρ, T) behavior of a refrigerant mixture of 50.00 mass% R1234yf and 50.00 mass% R290 was measured with the isochoric method. Along the six isochores (60, 121, 305, 500, 550, and 600 kg·m–3), a total of 40 single-phase (p, ρ, T) data points were obtained at temperatures from 330 to 400 K and pressures up to 6.6 MPa. In addition, the phase boundary of this mixture was experimentally investigated by visual observation of the vapor–liquid meniscus, and a total of 17 saturated densities and the critical parameters were obtained. Additionally, five saturated densities were also determined from the inflection points of the isochores. According to the multifluid approximation approach, a thermodynamic mixture model was formulated for R1234yf/290 mixtures. The parameters of the mixture model were determined by fitting the experimental data obtained in this work and those available in the literature. Expected uncertainties (k = 2) in calculated values with the mixture model are 0.2% for bubble and dew point pressures, 0.2% for liquid densities, 0.4% for vapor densities, 1% for saturated liquid and vapor densities, and 1.5% for isochoric heat capacities in the liquid phase. The mixture model can also be applied to regions away from the fitted experimental data with reasonable accuracy because it extrapolates well to higher temperatures and pressures, and to lower temperatures.

Aiming to explore environmentally friendly working fluids replace R134a for automotive air conditioning applications, seven potential pure refrigerants were analyzed first in terms of safety, environmental characteristics, and cycle performances. It was found that the pure refrigerants have some defects when applied individually. However, using the principle of complementary advantages, the mixtures employed in automotive air conditioning can make up for the shortcomings existing in the pure refrigerants. On this basis, the thermophysical models of vapor‐liquid equilibrium, enthalpy, entropy, and critical properties of binary mixtures were established. Also, the properties and cycle performances of 14 blends were investigated, and the results indicated that the predicted models of vapor‐liquid equilibrium have high accuracy, where the average absolute relative deviations of pressures and the average absolute deviations of vapor‐phase mole fractions were less than 2% and 0.005, respectively. M1 (R13I1/R152a [30/70]) and M11 (R13I1/R290 [40.3/59.7]) showed superiorities in cycle performances and environmental and safety characteristics. Moreover, the operating pressures of which were close to that of R134a, and they were expected to become the substitutes for R134a in automotive air conditioners.
