Viscosity measurements of compressed liquid refrigerant blend R-507A, using a v...
Avelino, Helena M. N. T.; Fareleira, João M. N. A.; Oliveira, Carla Padrel deThe refrigerant blend R-507A (50 wt % HFC-143a, 50 wt % HFC-125) is an azeotropic mixture of hydrofluorocarbon refrigerants, 1,1,1-trifluoroethane (HFC-143a) and pentafluoroethane (HFC-125). The paper reports viscosity measurements, performed with a vibrating-wire viscometer, of the refrigerant blend R-507A,at five temperatures in the range (253 to 293) K. The measurements were carried out at pressures from sli...
