01 Background
Project Background
A ventilation and dust-removal project covering several teaching buildings and the canteen. High-pressure cabinets paired with water-cooled fresh air units form the scheme: the high-pressure cabinets overcome the resistance of multi-level ceilings and multi-bend ductwork to supply distant classrooms, while the fresh air units continuously deliver cooled air, replace stale indoor air and filter dust. Centrifugal fans assist canteen exhaust. Corrosion-resistant galvanized casings suit the humid environment, and variable-frequency airflow control enables energy-efficient operation.
Fresh air, exhaust and fume-extraction equipment configured for classrooms, canteens and activity venues, based on on-site space and operating duty.

02 On-Site Problems
On-Site Problems
Closed, stuffy classrooms with poor airflow; concentrated canteen fume with odor spread; noise-sensitive campus areas; and some zones needing dust control.
03 Equipment Used
Equipment Used
Water-Cooled Fresh Air Unit
Delivers cooled fresh air to relieve stuffiness and stale air.
Backward-Curved Cabinet Fan
High pressure for long canteen exhaust duct runs.
04 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.

05 Installation Process
Installation Process
Silent cabinets are placed in teaching-plant rooms, fresh-air units on rooftops or platforms, and canteen exhaust cabinets connected to hoods and ducting, all on vibration-isolation bases with zoned ducting for easy service.
06 Results
Results
Continuous fresh air in teaching areas, markedly less stuffiness, smooth canteen exhaust without odor spread, and quiet operation that does not disturb teaching, clearly improving air quality and comfort.
