The paper simulates the airflow in the microenvironment of negative pressure isolation cabin for the infectious disease patients. The result shows that the proper setting of such parameters as air inlet, air outlet, fan flow rate, and differential pressure control can effectively discharge the contaminated air out of the tank after the air is efficiently filtered. During the cabin ergonomic evaluation experiment based on different negative pressure values, the temperature and humidity rise slightly compared with the external environment but there is no obvious accumulation. Besides, the human life indication is consistently kept in the normal range.
