Information

Currently, one modeling approach is implemented in the refrigerants' library:

1. Hybrid Approach: The hybrid approach uses the both the Helmholtz equation of state (EoS) and polynomial functions. The polynomial functions are used to avoid iterations that normally occur while using modeling approaches only based on the EoS.

Assumptions and limitations:

Up to this point, the modeling approaches implemented in the library are only valid for pure and pseudo-pure refrigerants. Consequently, calculation procedures of pseudo-pure refrigerants are only roughly valid within the two-phase region.
