Summary
Vapor-liquid equilibrium was measured for two binary refrigerant blends containing a novel HFO refrigerant, R1132(E) at seven temperatures between 263 and 323 K. As the normal boiling point of R1132(E) is very close to that of R32, three different mixing ratios were measured for R1132(E) + R32, and two different mixing ratios for R1132(E) + R1234yf. From the obtained experimental data, the binary interaction parameters in the Peng-Robinson EOS were determined using the objective function. Using these parameters and experimental data, we drew a P-x diagram and compared the calculated dew and bubble point pressures with the experimental data.
