Gas mixture asked to the company: 50% CO2, 45% HFO, 4% iC4H10, 1% SF6. Reply from company:

"But unfortunately I do not have thermodynamic NASA-polynomials for the component HFO 1234ze, so I had to replace it by a similar component (HFO 1234yf). So there is an increased uncertainty in the calculations. All in all considering the uncertainty and that the mixture seems to be near the limit, I think it must be tested experimentally to have a reliable result."

11:35 → 11:55 EPDT status
