Design of ventilation system for an infectious disease hospital in Meizhou

Taking the design of the ventilation system for an infectious disease hospital in Meizhou as an example, this paper discusses the design principle of the “three zones and two channels” mechanical air supply and exhaust system of the infectious disease hospital. The design of the ventilation system under the combination of peacetime and epidemic periods in this infectious disease hospital is presented from air treatment, pressure gradient, air distribution, and air volume balance, which provides a reference for the design of similar projects.
