01 Background
Project Background
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.
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.
