R-514A Calculations #664

Open R-744 opened 1 week ago

R-744 commented 1 week ago

I need to do R-514A calculations but can't find this refrigerant or R-1130E to make it in mixtures. Can you confirm it is impossible to evaluate R-514A in Refprops or a method of doing so please . I'm using Refprop version 10 working in windows 10 using it in excel 365

There is an ECS model in:

Teraishi, R., Kayukawa, Y., Akasaka, R., Saito, K. Universal parameters of the extended corresponding states (ECS) model for hydrofluoroolefin refrigerants. Int. J. Refrigeration 131:33-40 (2021).

But that is all that we have given the experimental data currently available.

You can email me (ian.bell@nist.gov) for an implementation of that model that can be used in REFPROP.
