Laboratories are both critical environments and important workplaces for researchers. The concentration control of internal pollutants is very important to the safety of laboratory researcher. The exposure control device (ECD) and HVAC system play a decisive role as the key methods of laboratory pollutant control. Taking a university laboratory renovation project as an example,this paper presents the HVAC system design for the laboratory renovation project from the aspects of diversity factor, VAV control, air distribution, re-entrainment pollution, air change rate, typical laboratory design and so on.
