5. CO2 Controlled Ventilation
• Based on actual occupancy
• Perfect ventilation
• Saves energy

6. How much energy can we save?
Calculation of the energy needed for
ventilation and heating of a small area like a
villa, apartment or smaller office.
Based on a small office

9. ▪ Sense CO2 to enable
▪ Ventilation control in the cabin
▪ Energy saving, reduce fuel consumption
▪ Air quality monitoring in the cabin
▪ Leakage alarm for R744 (CO2)

10. Full air-recirculation is chosen when
lower air temperature is desired with
a limited power of the vehicle air
conditioning system. Full recirculation
is also chosen by passengers to
prevent some visible smoke or dust
from entering the cabin.

11. Ventilation fan speed is more
important at low vehicle speeds
while the vehicle speed drives
body leakage at high speed.

12. A study published in
Springer Nature America
shows results that are
rather convincing.
The risk that airline
pilots make a mistake
increases with 50% at
the level of 2500ppm
compared to results
measured in fresh air
(close to 400ppm). You
will find more studies
done in different
environments in “A
Review of Cognitive and
Behavioral Effects of
Increased Carbon
Dioxide Exposure in
Humans”, published by
NASA in Aug 2016.

13. Carbon Dioxide Poisoning?
that elevations of carbon
dioxide (CO2) commonly
found in modern buildings
will stimulate leukocytes to
produce microparticles
(MPs) and activate the
nucleotide-binding domain-
like receptor 3 (NLRP3)
inflammasome due to
mitochondrial oxidative
stress
Increased carbon dioxide levels stimulate neutrophils to produce
microparticles and activate the nucleotide-binding domain-like
receptor 3 inflammasome
