SH-VT150C Rev F
1. SUMMARY
Most of us spend 90 % of our time indoors. Consequently, good indoor
air quality is important to our wellbeing. All human beings produce
carbon dioxide gas by respiration, thus the carbon dioxide level can
be used as an indicator for indoor human presence. A high CO2 level is
a sign of poor ventilation and often an indication of other unpleasant
odors in the air. In many buildings the ventilation need varies throughout
the day. Demand controlled ventilation is an economical way to ensure
good air quality.
