DCV – demand controlled ventilation
The airflow is varied as required;
DCV is a stepless regulation of the airflow individually in the individual zones.
In addition to controlling the ventilation in the individual rooms, depending on when they are used, you can also regulate the airflow depending on how much they are loaded using CO2 and temperature measurements.
Clock and weekly schedule control on/off of basic ventilation
CO2 and temperature sensors gradually increase the ventilation in the individual rooms as the load increases
A regulator maintains constant pressure in the ducts so that the air volume is distributed correctly
We recommend DCV when:
- Rooms are used periodically
- The number of people using the room varies
- Heat load varies over the day
Examples of this are:
School: teacher room, south-facing classrooms, SFO, gymnasium, changing rooms and classrooms.
Office: meeting rooms, canteen, south facing offices
The solution - pros and cons
Benefits
- Ventilation follows the load in the rooms
- Fully automatic control
- Fewer weekly schedule updates
- Great energy savings
Cons
- Expensive installation
