英文摘要：

Abstract： This paper studies the refrigerant thermodynamic parameter algorithm and mathematical methods of linear interpolation design of refrig- erant thermodynamic calculation software. The thermodynamic parameters of the powerful software can query multiple refrigerants, also has the advantages of simple operation, easy to use, solve the calculation software in refrigeration engineering look-up table is not convenient and many parameters can not find the problem, reduce the amount of calculation work, provides many conveniences for the engineering staff.
