Core requirements

Safe removal of hazardous gases from laboratories, comfort levels in classrooms and libraries, stable temperature and humidity control in precision instrument rooms, and energy conservation and consumption reduction.

 

Dedicated technical adaptation

• Laboratory Safety Ventilation The chemistry laboratory is equipped with fume hoods and omnidirectional exhaust hoods. Each fume hood is independently linked to a variable-frequency fan; when activated, the fan automatically increases the air volume in the corresponding area, maintaining a negative pressure of ≥0.5 Pa inside the fume hood to prevent leakage of harmful gases. The biological laboratory employs a high-efficiency filtration and exhaust system; the exhaust gases are filtered to meet emission standards before being released, thereby avoiding biological contamination.

• Dynamic Adaptation of Teaching Areas In classrooms and auditoriums, a dual-control system—combining occupancy sensing with CO₂ concentration monitoring—is employed. When the CO₂ concentration exceeds 1,000 ppm or the number of occupants surpasses the capacity, the system automatically increases the fresh-air supply to ensure that teachers and students can maintain their focus. In libraries and self-study rooms, a design featuring “low air velocity + uniform air distribution” is adopted to prevent direct airflow while keeping the CO₂ concentration below 800 ppm, thereby enhancing learning comfort.

• Specialized Control for the Precision Instrument Room In areas such as the physics laboratory and the electronics research lab, the ventilation system is linked with the temperature and humidity control system to maintain temperature fluctuations within ±1℃ and relative humidity below 55%. The fans feature a vibration-free design to prevent airflow disturbances from affecting instrument accuracy. Additionally, fresh air is efficiently filtered to minimize dust-related damage to equipment.
