Abstract：
The application of variable air volume control system to chemical laboratory HVAC system is described from the aspects of fume hood variable air volume control, laboratory pressure control and fan variable frequency drive control. Taking a chemical synthesis laboratory as an example, combined with diversity factor and operation mode, the variable air volume system under different operating conditions is compared, and the advantages of the variable air volume control system in terms of initial investment, energy saving and emission reduction are analysed.
