Best choice against poor indoor odor and
VOC air quality detectors are important for the indoor climate in
Below you will find a summary of what they can achieve.
Imagine a commercial building where the ventilation system is
controlled by VOC.
During evening hours, the presence and hence the ventilation levels
are very low because there are only cleaning personel and guards in
If the cleaning personel start using chemicals that are sensitive to
the detector, a higher level of ventilation activated by the
detectors until all contaminants are completely removed from the
Detectors thus measure different things and have different
applications. Make sure that the correct sensor is selected for each
A CO2 sensor is used to control the ventilation. They detect actual
presence in a space.
Air quality sensors can regulate ventilation and detect
sensor-specific contaminants and actual presence in the space.
Each method will result in completely different ventilation
strategies and energy effects.
The cases, reported in "sick buildings" vary a great deal, but seem
to be valid for:
Faint but persistent odor
The number of identifiable components in indoor air can be up to
But there is always a group of about 20 to 30 substances that are
found in most samples, while the others occur only in isolated cases.
Several of the materials identified in indoor air have also been
found in emissions from building materials.
It has also been shown that in the residential environment it is
mainly construction and furnishing materials that emit organic
compounds into indoor air.
Chemical Indoor air pollution:
Construction and furnishing materials
Combustion indoor heating, wood or gas stove
Exhaust fumes from cars and combustion gases from outside.
"Sick Buildings" are essentially a physical environmental problem
and not a psychological one.
Sense perceptions dominate among the symptoms in the syndrome of
OR485 to see Modbus network configuration.
