Systems Building Automation /Management System
Building Types Industrial
Description of the building:

The pharmaceutical factory building has a gross floor area of around 3,500 square meters.

The cleanrooms in the factory are served by an HVAC system that consists of three water-cooled chillers and two boilers.

On the air side, fresh air is cooled by the PAU and mixed with recirculation air in the AHUs. Cooling coils and heating coils are installed in the AHUs for temperature and humidity control. To maintain the required cleanliness in the cleanrooms, high recirculation airflow is maintained and passes through HEPA filters. Room static air pressure is also controlled to prevent particle transmission from lower-level spaces to higher-level spaces.
