Abstract
Natural refrigerants such as hydrocarbons (HCs) are considered as promising long-term alternatives in some of the restricted applications for refrigeration systems, since they have zero ozone depletion potential (ODP) values and negligible global warming potential (GWP) values. One of the crucial disadvantages of HCs, however, is flammability. For the purpose of solving this important issue, we have decided to study the thermodynamic properties of binary mixtures of HCs blended with nonflammable HFC refrigerants. The present paper, therefore, aims to measure a set of reliable PVTx property data for the binary 1,1,1,2-tetrafluoroethane (R-134a) + propane (R-290) mixtures in two-phase and gas-phase regions. The experimental PVTx properties of the binary R-134a + R-290 system have been measured at four different compositions by a constant-volume method coupled with expansion procedures in an extensive range of temperatures from 312 K to 400 K, at pressures up to 6.1 MPa, and for densities up to 196 kg·m-3, r...
