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.
