More Information About DCV With a CO2 Sensor
DCV is an automatic reduction of outside air intake to meet the actual occupancy requirements of a space.
How DCV With a CO2 Sensor Works
Conventional ventilation systems operate at pre-determined ventilation rates, generally based on the maximum occupancy level of the building. Because the level of occupancy changes continuously throughout the day, energy is wasted when occupancy drops below these pre-set rates.
The process of DCV is used to ventilate as well as condition the air during heating or cooling periods, based on the level of occupancy at any given time. Sensors are used to monitor conditions in the occupied space and provide real-time feedback to the controls. The controls then determine the fan speed, which modifies the ventilation rates to match the number of occupants in the building.
Benefits
- Increased energy savings
- Reduced operating costs
- Improved thermal comfort
- Less environmental impact
Maintenance
Like all components of an HVAC system, routine maintenance is required. In specific circumstances, there may be a specific maintenance plan in place. The maintenance plan provides for inspection and calibration of control system components, including sensors, actuators and transducers.
Building Applications
DCV with sensors is ideal for buildings with varying occupancy levels, such as office buildings and retail stores.
