Demand-Controlled Ventilation: Smarter Airflow for Greater Efficiency
Ventilation systems are designed to handle a wide range of indoor climate challenges, ensuring optimal comfort and air quality. To achieve this, systems are typically designed to meet peak demand conditions—accounting for factors such as outdoor temperature fluctuations, solar radiation, and occupancy levels. However, since these conditions constantly change, ventilation systems often operate with more capacity than needed.
By dynamically adjusting airflow based on real-time demand, we can significantly reduce unnecessary energy consumption while maintaining a comfortable and healthy indoor environment.
Key Benefits of Demand-Controlled Ventilation:
- Lower airflow through the system → Reduces pressure drop for more efficient operation
- Decreased air velocity → Reduces noise levels, improving comfort
- Less air movement required → Reduces fan energy consumption and operating costs
- Minimized intake of cold outdoor air in winter → Lowers heating demand
- Minimized intake of warm outdoor air in summer → Reduces cooling load
How It Works
Ventilation adjustments are made through modulating dampers and speed-controlled fans, which automatically regulate airflow based on real-time data. This system can be controlled using various sensors that monitor temperature, air quality, CO₂ levels, and occupancy, ensuring that air supply matches actual demand rather than running at full capacity at all times.
By implementing demand-controlled ventilation, we create a more efficient, cost-effective, and sustainable onboard climate system.
