01 Background
A campus cooling and ventilation project covering teaching buildings, the canteen and sports facilities. Water-cooled fresh air units are the core, with high-pressure cabinets and centrifugal fans as support: the fresh air units deliver clean cool air to classrooms, the high-pressure cabinets move main-duct air against complex resistance, and the centrifugal fans extract canteen fume and steam. Airflow is sized precisely by floor area, and rust-resistant casings suit the humid southern climate for integrated fresh-air supply, exhaust and dust filtration.
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
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

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.

04 Our Solution
Zone the equipment by teaching area, canteen and venues, balancing airflow, operating noise and long-term maintenance.
05 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
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.
