Investigating the use of different fluids and their advantages in new energy systems has increased the need for faster and more robust simulation models. The need to explore the potential of new fluids in different systems requires dynamic simulations for longer periods of time. In this paper; development of a medium model for propane is discussed. Besides being fast and accurate; the propane model should also be stable in different dynamic simulation scenarios.
First; existing libraries are tested and in some cases modified to increase the stability. Since the simulation speeds were not in an acceptable range in the existing models; a new propane model is introduced. The new model is then tested as a refrigerant in a direct exchange heat pump system. A comparison between an existing propane model and the new model shows that much faster simulations; up to 35 times; are possible with the new propane model.
