In this paper, the authors research the calculation of equipment module, which consists 1 compressor, 2 expander and throttle valve, 3 separator, 4 mixture, 5 multi- flow heat exchanger. The calculation of the compression process, throttle process, mixture process, separation process is compared with the data obtained by the overseas researchers. The comparison indicates the calculation of equipment module in this paper is correct.
