DEMAND CONTROL VENTILATION What is Demand Control Ventilation? Demand Control Ventilation (DCV) provides you and your home with the right amount of fresh air, when you need it. DCV automatically removes stale air from your home and circulates fresh air. DCV units are sensitive to humidity, so in rooms like kitchens and bathrooms where there is an excess of moisture, the air is automatically recycled with clean, fresh air as needed. How does the system work? A central extract fan is located in either the attic or storage area. This fan runs quietly 24/7. The fan is ducted to the wet rooms such as kitchens and bathrooms. Extract grills in the ceiling adjust depending on the humidity level to determine the amount of air extracted from each room. Fresh air is then drawn into the house through wall or window vents located in the bedrooms and living areas. These vents open and close depending on the ventilation requirement. The results leave clean air with minimal heat loss. Benefits of Demand Control Ventilation •Better air renewal for greater comfort, providing the most ventilation for the places in the home that need it most. •Protection against moisture by quickly evacuating excess moisture and eliminating the presence of condensation in kitchens and bathrooms. •Reduced and controlled heating consumption. Sensors determine the correct amount of airflow for each room in the home, reducing energy consumption and thermal losses. Read more of our guides at www.cairnhomes.com
