Bubble Point Measurements of Three Binary Mixtures of Refrigerants: R-32/1234yf, R-32/1234ze(E) and R-1132a/1234yf.

ABSTRACT: Bubble point pressures of three binary mixtures at two compositions each have been measured utilizing a static method. The mixtures studied were: difluoromethane + 2,3,3,3 tetrafluoroprop-1-ene (R-32/1234yf), difluoromethane + (E)-1,3,3,3-tetrafluoroprop-1-ene (R-32/1234ze(E)) and 1,1-difluororethene + 2,3,3,3 tetrafluoroprop-1-ene (R-1132a/1234yf). For all the mixtures the minimum temperature measured was 270 K. The maximum temperatures measured for the R-32/1234ze(E), R-32/1234yf and R-1132a/1234yf mixtures were 360 K, 345 K and 325 K respectively. A total of 100 bubble point pressures are reported and compared to available literature data relative to the REFPROP database¹. Additionally, the bubble point pressures obtained in this study are modeled using the perturbed-chain st
