[Physical simulation of human body metabolism in sealed module on the ground].

Objective: To provide a test platform for experimental verification of environmental control and life support system (ECLSS) of manned spacecraft on the ground.
Method: According to characters of ECLSS ground simulation test, simulation of human body metabolism was divided into different units, and a ground metabolic simulator was designed.
Result: The ground metabolic simulator accurately simulated human body metabolic oxygen consumption, carbon dioxide production, water and heat productions in the sealed module.
Conclusion: The physical method for simulating human body metabolism is feasible and has the advantages of high precision and easiness of control. It can be used for verifying and appraising the function of ECLSS.
