In this work, the convenience of the (P,H) ensemble Monte Carlo simulation applied to process happening at constant enthalpy is showed. This was presented by means of the calculation of Joule-Thomson properties for 3 alternative refrigerants. Joule.Thomson coefficients and the complete Joule-Thomson inversion curves were calculated. The inversion curves were compared with previous results from Vrabec et al. presenting an excellent agreement. From this we can conclude that both methodologies conduct to equivalent results. The advantage to use the (P,H) ensemble Monte Carlo methodology in proces were constant enthalpy is involved, is the simplicity and fastness of its application.
