Abstract：Regarding the difficulty in controlling the fluctuation of room differential pressure gradient due to air pressure serial flow interference between key rooms of the filling line of pharmaceutical factory， this paper analyzes the composition of the HVAC system of the equipment in the key rooms of the filling line and the design architecture of the air valve and ventilation system， and takes the HVAC system and process equipment into account comprehensively. With the PLC control system， the room differential pressure can be adaptive to the process production mode switch to achieve intelligent control， which has been verified in actual project application.

Keywords：filling line; key workshops; CAV; VAV; pressure gradient; PLC
