CO2 in general
Big topic over the last year, everybody has it.. e.g. Green house effect and environment …
CO2 in general
CO2 in general
Photosynthesis:Chemical recation CO2 + H2O --> CHO + O2 + H2O
Carbon dioxide, water using light and chlorophyll, oxygen and glucose
CO2 in general
CO2 in generalIndoor air quality in offices leads to high or low levels of gases:
Since CO2 is exhaled by people at predictable levels the content of Carbon Dioxide - CO2 – in air may be a significant indication of air quality.
A measure of CO2 indicates the amount of fresh air supply:15 cfm = 7.0l/s ventilation rate per occupant
corresponds to 1000 ppm CO2
20 cfm = 9.2l/s ventilation rate per occupant corresponds to 800 ppm CO2
Normal CO2 LevelsThe effects of increased CO2 summarized:
• normal outdoor level: 350 - 450 ppm• acceptable levels: < 600 ppm• complaints of stiffness and odors: 600 - 1000 ppm• ASHRAE and OSHA standards: 1000 ppm• general drowsiness: 1000 - 2500 ppm• adverse health effects expected: 2500 - 5000 ppm• maximum allowed concentration within a 8 hour working period:
5000 ppm

CO2 in general
Extreme and Dangerous CO2 Levels
• slightly intoxicating, breathing and pulse rate increase, nausea: 30,000 ppm
• above plus headaches and sight impairment: 50,000 ppm
• unconscious, further exposure death: 100.000 ppm
