We need the test data of propane/R290 and isobutane/R600a solubility in POE lubricant oils. The data will be used to model the refrigerant quantity dissolved in compressor oils ( www.refriglab.com ) so that the unit refrigerant charge mass can be predicted. The solubility data of R290 in Poe22/32/68 and R600a in ISO10/POE7 were obtained from compressor manufacturers and oil companies.
We will much appreciate if you could present the references and/or any other sources of the solubility data.
I have a listing where such data is published. You can ask me via PN and ILK can offer the list with available data. But at first you can try https://www.amazon.de/K%C3%A4ltemaschinen%C3%B6le-Wolfgang-Bock/dp/3800732718
Some daniel plot and misibility diagrams of such oils with hydrocarbons are published in this book. If you need exact data, we can offer the measurement or the work within your project. We are very interested in such cooperation!
Best Regards
Steffen.
