01 Background
Project Background
A ventilation retrofit designed around the high noise and air-quality requirements of primary school pupils. Silent cabinets with multi-layer sound absorption run quietly in the plant room without disturbing teaching, while water-cooled fresh air units pretreat, cool and filter outdoor air to improve classroom conditions. Backward-curved cabinets provide strong pressure for fast canteen fume discharge. All equipment sits on vibration-isolation bases, and the zoned control adjusts airflow flexibly by teaching period.
Fresh air, exhaust and fume-extraction equipment configured for classrooms, canteens and activity venues, based on on-site space and operating duty.
