Demand Controlled Ventilation (DCV)

2020-11-23· Carbon Dioxide (CO2) sensors are generally used to estimate the occupancy of a space relative to the outside air intake. If the CO2 concentration rises above the operating point, more outside air is needed. Likewise, if the CO2 concentration falls below the operating point, less outside air is needed. The CO2 concentration is a function of the space volume, the number of people, the ...
