Frequency control of ventilating system in an underground garage

By Zhang Ling, Yin Yingde,Huang Wensheng and Zhang Panyue Hunan University, Changsha, China  
Common intermittent control method and dual-speed fan method for VAV systems of underground garages are too simplified, can not remarkably improve air quality and can not furthest save energy. Puts forward a ventilation quantity control method by variable-frequency fan according to the real-time concentration of CO in underground garages. Presents the alteration of ventilation system to adopt a frequency control fan in an underground garage. The result shows that the reforming is technically feasible,and that it can save energy with short investment recovery period.
