| Abstract: | Taking ammonia refrigerating machine as an example in equation of gas state, which adopts virial equation, the adiabatic index k of compression process was obtained through entropy balance method. Then the efficient method was used to calculate each segment compression work Wpol. This article gave a de- tailed calculation process about centrifugal compressor power, analyzed the data error between the data of cal- culation and the data provided by vendors, and drew a conclusion that the calculation methods described above were feasible in front end engineering. |
