What is Demand
Control Ventilation?
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.
Ventilation Systems
for Commercial Kitchens
A typical commercial kitchen, with their various arduous ventilation systems, have relatively high resistances against which a fan has to operate. The varying cooking and heat loads are an ideal platform for demonstrating demand control ventilation. By utilising sensors, the levels of smoke, moisture, grease and cooking odours are maintained within set levels at all times.
Ventilation Systems
for Offices
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.
