pvTx properties for carbon dioxide (CO2)/difluoromethane (R32)/1,1,1,2-tetrafluoroethane (R134a) ternary mixture measured in the compressed liquid, superheated vapour, and two-phase regions [PDF]
, 2023 In low-temperature refrigeration applications, mixtures containing carbon dioxide and refrigerants with low triple points are considered potential substitutes for the refrigerant R23, characterised by a very high global warming potential.

Analysis of PVTx measurements for binary mixtures of R115 and R114 [PDF]
International Journal of Thermophysics, 1990 We have made PVTξ measurements of R115 and R114 at temperatures from 296 to 443 K, pressures from 0.4 to 9.8 MPa, and densities from 153 to 1387 kg·m−3, for four compositions, namely, 25, 50, 75, and 100 wt% R115. The data were obtained along isochores.

Bulletin of JSME, 1984 For representing PVTx state-surface of a binary refrigerant R 12+R 22 system, B-W-R equations of state for both pure components in combination with mixing rules for the coefficients were applied. Proposed B-W-R equations of state with new mixing rules for the system of interest were developed based on the PVTx measurements for seven different ...

Solid-liquid equilibria for the dimethyl ether plus carbon dioxide binary system [PDF]
, 2010 A recently built experimental setup was employed for the estimation of the solid-liquid equilibria of alternative refrigerants systems. The behavior of dimethyl ether (DME) + carbon dioxide was measured down to temperatures of 131.6 K.

An Experimental Study of the pVTx Propertiesfor Aqueous Solutions of Ammonia
, 2023 Abstract In order to know the hydrogen bonding effects on H2O+NH3 mixtures, the pVTx properties of H2O+NH3 mixtures were measured and reported some of them [1]. As the result, the phenomena of hydrogen bonding effects in H2O+NH3 mixtures were revealed for the first time. However, there were several misprinted data where the mixture composition

PVTx Properties of a Two-phase CO2 Jet from Ruptured Pipeline
Energy Procedia, 2013 AbstractSpan and Wagner equation of state (SW EOS) have been used to investigate changes in the thermodynamic properties of CO2 during a depressurization process from a pipeline into marine environment. The process is assumed to be isenthalpic, as only the thermodynamic change at the moment of depressurization is considered.
