Thoughts on epidemic prevention design and operation of air conditioning and ventilation systems in terminal buildings

In view of the impact of the COVID-19 on the air conditioning and ventilation system of the terminal buildings, this paper studies and analyses the system zoning design requirements based on risk identification, the necessity and feasibility of total outdoor air operation, and the key points of special space system design. It puts forward corresponding suggestions for the design, operation and management of the system, and also provides ideas for the construction of the air conditioning and ventilation system of the terminal building under the requirements of “combined normal with epidemic situation”.
