Comparison of ventilation system for junior middle school underground garage in Lingang J08-02 plot
Since the implementation of the Technical Standard for Smoke Management Systems in Buildings,the smoke exhaust duct of the garage has a certain fire resistance limit,which has a certain impact on the traditional duct ventilation system and induction ventilation system scheme of the underground garage.In order to better compare the two schemes,taking the underground garage of the junior high school supporting the J08-02 plot in Lingang,Shanghai as an example,the ventilation system was calculated and selected by the air exchange times method and the dilution concentration method,and the system form,initial investment,and annual operating cost of the two schemes were compared.The results show that,compared with the traditional duct ventilation system,the use of induction ventilation system can reduce the initial investment,the system is more energy-saving,the airflow during operation is well organized,the exhaust duct is reduced,and the pipeline layout is favorable.Studies have shown that compared with traditional ducted ventilation systems,induced ventilation systems are more economical and energy-efficient.
