Revision history [back]

I have a secondary classroom which needs to be ventilated based on CO2 levels. I have tried to use DCV by defining Controller:MechanicalVentilation and ZoneControl:ContaminantController. I have created minimum CO2 concentration schedule name of 500ppm and maximum CO2 concentration schedule name of 1000ppm.

Under normal circumstances, my max CO2 level was around 1800ppm. My purpose was to decrease 1800ppm to 1000ppm by defining DCV, but I am getting seriously higher CO2 levels ( around 6000ppm).

What may be the reason for this problem? The results without DCV the results with DCV

I have listed Controller:MechanicalVentilation and ZoneControl:ContaminantController objects in below figures.

The CO2 setpoint is 400ppm as dimensionless schedule, CO2 outdoor emission is 400 ppm which I defined as minimum emission, the CO2 indoor emission is 1000 ppm which I defined as maximum emission.
