01 Background
Project Background
A ventilation retrofit focused on classroom stuffiness, poor airflow and canteen odor spread. Water-cooled fresh air units supply fresh air, centrifugal fans assist exhaust, and backward-curved cabinets handle canteen fume. The fresh air units deliver cooled air and dilute indoor dust and stale air, the centrifugal fans accelerate air exchange, and the backward-curved cabinets discharge fume smoothly. Cost-effective, low-maintenance equipment suits the routine needs of a small-to-medium school.
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.
