What is Demand
Demand Control Ventilation or DCV, is a technological innovation that provides an effective, efficient means of using variable speed ventilation solutions to meet variable occupancy levels in spaces requiring ventilation.
Proper ventilation helps remove pollutants, odours, and contaminants from indoor spaces. It brings in fresh outdoor air and exhausts stale air, preventing the buildup of harmful substances such as carbon dioxide, volatile organic compounds (VOCs), and other pollutants. Controlling by demand ventilation ensures that the air quality remains within acceptable levels for health and well-being.
An office ventilation system relies on PIR sensors detecting movement, which in turn opens the relevant damper above the supply diffuser and ultimately reduces the pressure drop in the system. This system ensures that, when the office is occupied, the indoor air quality is comfortable and always maintained at preset levels.
