Variable Air Volume (VAV) systems from Datevi represent a modern, precise, and energy‑efficient solution for commercial buildings and large homes. Unlike traditional Constant Air Volume (CAV) systems, VAV systems modulate air supply based on room temperature, occupancy, and conditions—providing both comfort and savings.
🔧 How It Works
- A central Air Handling Unit (AHU) supplies conditioned air through ductwork.
- Each served room is fitted with a VAV terminal box, an airflow damper with precise control.
- Flow sensors and dampers automatically adjust the airflow based on temperature or presence in the space.
- Variable‑speed fans in the HVAC system maintain static pressure, optimizing energy use.
🌡️ Key Benefits of Datevi’s VAV Systems
- Zone‑by‑zone temperature control – each terminal box adapts to its room.
- Energy savings – variable airflow leads to lower fan and compressor energy.
- Quieter operation – fans run at partial load, reducing noise.
- Passive dehumidification – reducing moisture levels with minimal energy.
- Integrated heating options – electric or hydronic reheat coils ensure comfort during cool periods.
📍 Ideal Use Cases
- Large homes, villas, and multi‑zone residences
- Modern offices and business complexes
- Buildings with diverse temperature needs across zones
- Architecturally complex projects with high comfort requirements
