The calculation for refrigerant thermodynamic properties is a very important part for the numerical simulation of refrigerant system, so the study of calculation method is very valuable. In this paper, the fast calculation method based on the Martin -Hou EOS is developed for the calculation of refrigerant thermodynamic properties. Studying results used of refrigerant R22 shows high agreement to the reference data and high reliability in common encountered temperature range. In addition, the details of simulation algorithm is presented, which may give a reference for beginner.
