Engineering project
Hongling Experimental School, Futian District
A new ventilation system addressing poor classroom airflow and difficult canteen exhaust. Water-cooled fresh air units supply cooled fresh air and dilute indoor CO2 and dust; backward-curved cabinets act as the main canteen exhaust with ample pressure to prevent backflow; and silent cabinets serve public teaching areas with tight noise control. All equipment supports long continuous runs with service-friendly construction for routine maintenance.
Project overview
From the on-site air problem, determine equipment and air paths.

Key Questions to Confirm
Pollution & Heat Sources
Locate fume, oil mist, odor or heat sources.
Air Paths
Plan the direction of fresh air in and pollution out.
Installation & Operation
Check duct resistance, noise, energy and maintenance.
Our solution
Organize campus fresh-air supply and exhaust, balancing quiet and comfort.
Zone the equipment by teaching area, canteen and venues, balancing airflow, operating noise and long-term maintenance.
