* The BENDER equation and Peng-Robinsonequation with high precision adapted to air medium are adopted.
* Optimize the flow organization form, reasonably reduce the main condensing liquid level, reduce the temperature difference at the hot end of the plate-fin heat exchanger, so that the energy consumption of the device is reduced to the minimum.
