Most elevators rely on a fan at the top that pushes air downward, causing turbulence. This system forces passengers to inhale each other’s exhaled air, which increases the risk of airborne virus transmission. Additionally, continuously running fans waste energy and create noise, reducing passenger comfort.
Core Features of the Invention
- New Airflow Design: Instead of blowing air downward, this system pulls air upward from the bottom of the elevator cabin to the top, naturally removing contaminated air.
- Automatic Wind-Control System: A V-shaped wind baffle adjusts air intake depending on the elevator’s movement, allowing fresh air to enter efficiently.
- Energy-Saving Fan: A dual-purpose exhaust fan automatically activates only when needed, reducing electricity use and noise.
- Integrated Purification & Cooling: The system can include an air purifier and air conditioner to further improve air quality.
What Makes It Innovative?
- Bottom-to-Top Airflow: Unlike traditional fans that cause cross-contamination, this design ensures that exhaled air is immediately expelled, reducing virus spread.
- Adaptive Ventilation: The V-shaped wind baffle automatically adjusts air intake based on movement, enabling passive ventilation when the elevator moves, and active ventilation when it stops.
- Energy Efficiency: Since the fan doesn’t run continuously, it lowers power consumption and reduces noise pollution.
Benefits
- Healthier Air: Reduces the risk of airborne disease transmission in elevators.
- Energy Savings: Uses less electricity than standard ventilation systems.
- Quieter Operation: Passengers enjoy a more comfortable ride without constant fan noise.
- Better Air Quality: Integrated purification and cooling options improve passenger experience.
Broader Impact
This system can significantly enhance public health safety in office buildings, hospitals, malls, and other high-traffic locations. By improving energy efficiency, it also contributes to sustainability goals, making it a smarter, greener choice for modern buildings.
