CO2 Gas Concentration Defined |

Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 of them would be of carbon dioxide and 999,000 molecules would be some other gases. When you start counting over 10,000ppm, most scientists and manufacturers change from ppm to percent concentration. So instead of describing a …

Higher than 1000 ppm can affect respiratory, circulatory and brain functions, and even vomiting. It is suggested that before the improvement of these places, the public should try to go as far as possible, or select less crowded time to go or go outdoors every time when uncomfortable. Carbon dioxide is the gas produced by human respiration. When it is crowded and poor air flow, it will lead to high concentration …

What Is the Ideal CO2 Setpoint for Demand Control Ventilation ... - …

14/08/2019· When the CO2 accumulation difference exceeds 700 ppm, it means the ventilation system must increase the outdoor airflow (OA). There is an extra control requirement if the HVAC design includes an airside economizer. In simple terms, this is a device that increases the OA when its temperature is suitable to provide “free air conditioning”. This is independent from CO2 levels, and it may use the full …
