传染病医院空调通风系统设计浅析OA

Taking an infectious disease hospital as an example,this paper summarizes the requirements of the current national norms and guidelines for the design of pressure difference and air volume of the ventilation system of infectious disease hospitals,calculates the air volume of doors and windows,the fresh air volume of the room and the exhaust air volume in typical respiratory infectious disease areas,summarizes and analyzes the general rules of air supply and exhaust air volume in polluted areas,semi-polluted areas and clean areas,and finds that the actual calculated air volume in each area is often quite different from the air volume corresponding to the minimum number of air changes required by the code.It can provide reference data for the estimation of air volume in the funding stage of similar projects.Finally,the ventilation system design scheme adopted by the project and the related green building energy-saving measures were introduced.
