Sensors for Ventilation

Sensors for Ventilation

Sensors for Ventilation

(OP)

Hi Experts,

As I understand the new Ventilation meeting Energy savings would work on Carbon dioxide sensors output.
However in some occasions there has been cases where carbon monoxide sensors are also used.

I believe Carbon monoxide is used in Parking lots and Carbon dioxide in Human occupancy rooms. Am I right?
Can these sensors give a quantity estimate or just only presence is sensed.

BTW heard about small little towers that exhaust the extract from the basements being called as dog house towers. These towers are the less than 1metre high tower that have louvers blowing exhaust fan delivery out. They are built closer to the tall buildings.Is that the terminology being used for these exhaust towers in US and Europe regions.

Thanks in advance for the tips.

RE: Sensors for Ventilation

you are correct on CO for garages and CO2 for normal spaces requiring ventilation for humans. Cars produce CO (well, also CO2, but we are not concerned about that compared to CO), so that is what we are concerned with. Humans produce CO2.

Most sensors give you a value in ppm. but they also need to be recalibrated or replaced every so many years.

Not sure what towers you mean, like for natural ventilation? Code only allows natural ventilation under certain circumstances instead of mechanical ventilation. Most of the time you need to have large enough openings near the space. Like a parking garage that is open on the sides etc.
