On-Site Space
Confirm dimensions, openings, equipment and personnel.

Engineering project
A campus-wide ventilation, dust-removal and cooling retrofit covering teaching buildings, canteens and indoor sports venues. Xin Changfeng silent cabinets paired with water-cooled fresh air units form the fresh-air system, while backward-curved cabinets handle canteen fume and exhaust. The double-layer sound-insulated cabinets reduce operating noise; the fresh air units continuously supply cooled outdoor air; and the backward-curved cabinets deliver ample pressure for the canteens complex duct layout. The system balances fresh-air supply, exhaust, dust removal and cooling for stable, easy-to-maintain operation.

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.
