Solid–liquid equilibria for the CO2+N2O, CO2+R32, and N2O+R32 systems

Fluid Phase Equilibria, 2007
Abstract Evaluating the solid–liquid equilibrium and the eutectic composition of a mixture is fundamental for the estimation of the lowest temperature at which the blend can be used as a refrigerant fluid. The study on the solid–liquid equilibrium for some selected systems was undertaken to fill the gap in the literature on the solid–liquid ...

Measurements of isobaric heat capacity of R32

International Journal of Refrigeration, 2012
Abstract The specific isobaric heat capacity ( c p ) was measured for R32 (difluoromethane) in the gas phase. Thirty-two measurements for R32 were obtained at temperatures from 274 to 353 K and at pressures from 0.65 to 2.4 MPa. Some of them are close to the saturation curve.

Surface Tension and Liquid Viscosity of R32+R1234yf and R32+R1234ze

Journal of Chemical & Engineering Data, 2016
The surface tension and liquid viscosity of two binary refrigerant mixtures 1,1,1,2-tetrafluoroethane (R32) (1) + 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) (2) and R32 (1) + trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze) (2) have been measured from 293 K to the critical point by using the surface light scattering (SLS) method.

Vapor–Liquid Equilibrium Property Measurements for R32/R1234yf Binary Mixtures in Low R32 Concentration

International Journal of Thermophysics, 2020
This study obtained the precise measurements of the vapor–liquid equilibrium properties for R32/R1234yf binary mixtures, which are the key components for the next-generation refrigerant mixtures. To obtain the data more rapidly and precisely, two recirculation-type vapor–liquid equilibrium property measurement apparatuses installed in different ...

Investigation of Heat Pump Efficiency on Zeotropic Refrigerants R32/R134a and R32/R152a

Journal of Engineering Thermophysics, 2018
Results of analysis of thermodynamic cycle efficiency with consideration of nonisothermal nature of phase transition indicate that when using the mixture of R32/R152a (30/70%) in the vapor compression heat pumps, the coefficient of performance is up to 4% higher in comparison with R32/R134a (30/70%).

Thermodynamic properties of R32 + R134a and R125 + R32 mixtures in and beyond the critical region

International Journal of Refrigeration, 1998
Abstract A parametric crossover equation of state for pure fluids is adapted to binary mixtures. This equation incorporates scaling laws asymptotically close to the critical point and is transformed into a regular classical expansion far away from the critical point.

Transport properties of refrigerants R32, R125, R134a, and R125+R32 mixtures in and beyond the critical region

International Journal of Refrigeration, 1999
Abstract A practical representation for the transport coefficients of pure refrigerants R32, R125, R134a, and R125+R32 mixtures is presented which is valid in the vapor–liquid critical region. The crossover expressions for the transport coefficients incorporate scaling laws near the critical point and are transformed to regular background values far ...
