Engineering project
A ventilation retrofit designed around the quiet needs of a senior high school. Silent cabinets with multi-layer soundproofing run quietly, and water-cooled fresh air units deliver cooled air while diluting indoor CO2 and dust. Backward-curved cabinets extract cooking fume from the canteen to prevent odor spread. Full vibration isolation keeps vibration low, and power adjusts by teaching period for energy efficiency, balancing quiet with ventilation performance.

Project challenge
Confirm dimensions, openings, equipment and personnel.
Locate fume, oil mist, odor or heat sources.
Plan the direction of fresh air in and pollution out.
Check duct resistance, noise, energy and maintenance.

Our solution
Zone the equipment by teaching area, canteen and venues, balancing airflow, operating noise and long-term maintenance.
Products used

Low-noise, vibration-isolated air supply for quiet areas like classrooms.

Delivers cooled fresh air to relieve stuffiness and stale air.

High pressure for long canteen exhaust duct runs.
