Research on air conditioning and ventilation systems design in infectious disease hospitals combined with epidemic prevention and control
Summarize the experience of air conditioning and ventilation systems design in infectious disease hospitals before and after the ep-idemic,analyze and discuss the different requirements of the air conditioning and ventilation system in terms of ventilation volume,air filtra-tion,and pressure gradient in the design of combined epidemic prevention and control.At the same time,sort out thedesign methods and rapid conversion strategies for the air conditioning and ventilation systems in negative pressure wards,negative pressure isolation wards,and negative pressure operating rooms.In the design and selection of the air conditioning and ventilation system,consider reducing the waste of resources and reducing the operating energy consumption in normal times.After the operation and commissioning of the ventilation and air conditioning system,meet the pressure gradient requirements of different areas,achieve orderly directional flow and reasonable air distribution between the three zones,and reduce the risk of infection for personnel.
