DCV - Demand controlled air volume

Individual DCV variable regulation of airflow in each zone.

As well as being able to control the ventilation in each room independently of when they are being used, airflow can also be regulated regardless of load with the help of CO2 and temperature measurements.

 DCV is typically used when:

- Rooms are used periodically
- There are large variations in the number of people in a room
- There are large variations in heat load

Examples: Staff room, south-facing classrooms, after-school clubs, gymnasiums, changing rooms and special subject rooms.

Features Advantages Disadvantages
- Clock and week plan control on and off times
  for basic ventilation
- CO2 and temperature sensors gradually
  turn up the ventilation
  in the individual rooms as
  loading increases
- A regulator maintains a constant pressure
  in the duct system,   so that airflow
  is correctly distributed
- Ventilation adjusts to load
  in the rooms
- Regulation is fully automatic
- Less updating of week plan
- Big energy savings
- Expensive installation
