Theoretical gas phase compressibility factor of mixed refrigerants in auto-cascade refrigeration system

摘要

The compressibility factor is solved using the RKS equation and the corresponding calculation program. Redlich-kwong-Soave the numerical calculation method for solving the compressibility factor, R22 and CO_2 is calculated and compare it with standard values, so as to verify correctness of program. Finally, calculate the compressibility factor of mixed refrigerants R14/R23/R22 in a three-stage auto cascade system. At the same time, provide reference for solving it in auto-cascade system.
