THERMOPHYSICAL PROPERTIES OF R-407C AND R-507A REFRIGERANTS IN THE LIQUID AND GASEOUS STATES
New experimental saturated vapor pressure (290-338 K), density (300-363 K, 1-3.5 MPa), thermal conductivity (303-425 K, 0.1-1.8 MPa), and speed of sound (293-373, 0.01-0.5 MPa) of the mixed refrigerants R-407c and R-507a in the gaseous phase, R-407c speed of sound (293-323 K, 1-4 MPa) and R-507a thermal conductivity and heat capacity (298-333 K, 1.5-3.8 MPa) in the liquid phase have been obtained. The tables of the temperature and pressure dependences of the properties have been constructed. Comparisons between our results and known reference data have been carried out. It is shown, that theory of thermodynamic similarity (Lee-Kesler method) allows to provide relatively reliable data on PVT-properties of the blend refrigerants using only data for pure components.
