Carbon dioxide tracer gas method was used to verify the mixing uniformity of fresh air and the airtight performance of human metabolic chamber.At the same time,the human metabolism simulation device based on indirect calorimetry is used to accurately simulate the carbon dioxide output and oxygen consumption of human respiration without affecting the gas environment inside the human metabolism chamber,and the nitrogen lost during the consumption of oxygen is added to the metabolism chamber,and the simulated standard metabolic amount is calculated according to the Weir formula.Compared with the results of metabolic capacity test in metabolic chamber,the deviation of the two test results is better than±10%.The experimental results can finally verify the accuracy of the results of human metabolic chamber metabolism.
