Description

This paper presents the results of a set of experiments performed in an HVAC aboratory to evaluate the effect of CO2 -based demand-controlled ventilation strategies on energy consumption and occupant source contamination concentration. First, CO2 levels were monitored for various ventilation rates at different zone pressures for a specific occupancy profile. The effect of various occupancy profiles and ventilation rates on CO2 level within the space were also investigated. Then, one-zone controls were investigated to maintain an acceptable indoor air quality with a CO2 setpoint of 1000 ppm. Three different control strategies are considered here, namely: on/off control, proportional or linear control, and proportional-integral-derivative (PID) control. Finally, one-zone and two-zone controls to maintain both CO2 level and indoor temperature at specified setpoints were investigated.
