Abstract

A small two-bed pressure swing adsorption oxygen generator was designed and a series of experiments were carried out in the low-pressure cabin. The influences of structure and operating parameters were investigated simultaneously. The mathematic model of oxygen production process was established. The model was matched with the experiment results to verify the accuracy of the model. Numerical simulation and simulation researches were carried out to determine the relevant intrinsic parameters and external factors on the process of oxygen production and the effect of oxygen production. Performance of oxygen generator at different altitudes with different operating conditions

design parameters and operating parameters were studied to improve the oxygen production efficiency and reduce the manufacturing and operating costs of oxygen generator.
