Organic Rankine cycle with a wet working fluid

Buildings.Fluid.CHPs.OrganicRankine.BaseClasses.Validation.WetFluid

Information

This model is largely the same as Buildings.Fluid.CHPs.OrganicRankine.BaseClasses.Validation.DryFluid, except that it validates the handling of wet working fluids. As a result, a superheating temperature is computed that ensures the expansion does not land under the dome. How this superheating temperature is found is explained in the documentation of Buildings.Fluid.CHPs.OrganicRankine.ConstantEvaporation.
