DCV is an intelligent ventilation method that ensures good indoor air quality, saves energy and consists of sensors, controllers and ventilation fans. The sensors continuously measure and monitor indoor air quality and provide real time feedback to the controller.
The controller conveys the sensor information to the fans, adjusting the rate of ventilation according to what is happening in each room.
The extracts fans, which are barely audible, are placed in the attic spaces or utility rooms and are connected via ducts to extract grilles in wet rooms (Kitchen, bathroom, utility). Fresh Air comes into the house through passive or humidity sensitive wall vents or window vents in the habitable rooms (bedrooms, living rooms).
What are the benefits of Demand Control Ventilation?
Reduced Allergens and Improved Indoor Air Quality (IAQ)– When buildings are not properly ventilated, allergens, pollen, VOCs, fumes from chemicals, pet dander, dust and other pollutants can build-up in the air. This can result in indoor air that is significantly more polluted than the outside air. DCV helps reduce indoor air pollutants by allowing stale air to be extracted when and where and also promote fresh air into the building.
Improved Energy Efficiency Means Lowering Building Operating Costs – DCV is controlled via CO2/Humidity sensors. When CO2/humidity levels are high or the area of the building is occupied, the ventilation system activates. Once the CO2/humidity levels return to acceptable levels or the area of the building is determined to be unoccupied, the ventilation system switches to a lower speed.
Smart Ventilation Control– In addition to sensors many DCV systems can be set according to zone and be app controlled vary phone.
