Abstract：
Aiming at the switch control, air volume control, temperature and humidity control of air conditioning and ventilation system of chemistry laboratory, analyses the design and commissioning of automatic control scheme from the angle of process and energy saving. Especially the full variable air volume and partial variable air volume two design schemes, adopts two stage control thought and method, it can realize the room ventilation requirements and minimize the energy consumption.
