Hey Remi! I have worked on R245fa/POE mixture before. I will send you a Python file with the properties that I have.

The following papers report the data you are after for a mixture of R245fa/synthetic POE 100.

Zhelezny et al. "An experimental investigation and modeling of the solubility, density and surface tension of 1,1,1,3,3-pentafluoropropane(R245fa)/synthetic polyolester compressor oil solutions" Journal of Fluorine Chemistry 128(2007), 1029-1038.

Zhelezny et al. "An experimental investigation and modelling of the viscosity refrigerant/oil solutions", International J. of Refrigeration, 32(2009), 1389-1395.

An interesting work to estimate thermophysical properties of lubricant oils and their solutions is:

Conde,M.R., "Estimation of thermophysical properties of lubricating oils and their solutions with refrigerants: an appraisal of existing methods", Applied Thermal Engineering 16(1996),51-61

You rock! Thanks a lot :)

Hi,

I'm working on the RL32H lubricant too, and I can't find anywhere it's specific heat capacity.. Could you please send me the infos ?

Thanks

Arnaud

Hi Arnaud,

Ultimately I did not work with RL32-H but with RL32-3-MAF. In any case, here are the equations I am using to calculate its cp, rho and viscosity, if it can be useful for you. I have fitted these equations either based on Emkarate datasheet or with values found in the literature.

cp (J/kg.K) = 1159 * T + 2.3639

rho (kg/m³) = 981 - 0.7547*(T-273.15 - 20)

mu (Pa.s) = exp(-14.48 + 3439./T)

with T in K

Thanks a lot Rémi !
