· Der VOC kann CO2 nicht messen, gibt aber CO2-Äquivalente aus. "Meine" CO2-Werte (mit CO2-Sensor) steigen ohne Lüftungsanlage schon relativ deutlich an bei geschlossenen Fenstern. Wenn zusätzlich zu den atmenden Menschen noch ein Kerzchen Luft verbrennt sind das schnell mal 400ppm/Stunde und nachts im Schlaf immer noch 100ppm/Stunde. Hängt natürlich auch von der …

Explanation on static IAQ, breath VOC and CO2 equivalent

· The breath VOC equivalent output (bVOC eq) estimates the total VOC concentration [ppm] in the environment. It is calculated based on the sIAQ output and derived from lab tests. CO2 eq estimate: Estimates a CO2-equivalent (CO2 eq) concentration [ppm] in the environment. It is also calculated based on the sIAQ output and derived from VOC measurements and correlation from field …

CO2 equivalents | Climate Change Connection

· 1 x – carbon dioxide (CO2) NOTE: Any carbon dioxide added to the atmosphere will hang around for a long time: between 300 to 1,000 years. All this time, it will be contributing to trapping heat and warming the atmosphere. 84 x – methane (CH4) – Releasing 1 kg of CH4 into the atmosphere is about equivalent to releasing 84 kg of CO 2.

What do you get when you measure CO2 vs VOC

The VOC donor captures thousands of subjects, and instead of setting limit values for all of these substances, the VOC sensor is constantly calibrated to distinguish what is background level and what are changes, that is, the addition of contaminants. In other words, it is not as easy to set absolute limit values for VOCs. However, in a modern system for demand-controlled ventilation, this is ...

VOC Sensor Capabilities and Limitations - Application Note ...

The BAPI VOC sensor provides a CO2 equivalent ppm output so that Ashrae’s popular CO2-based VRP procedure can be used for DCV; however, CO2 is not one of the VOCs that the sensor monitors. If your application needs to directly measure CO2, choose a CO2 sensor. Commissioning and Testing. BAPI’s VOC sensor is easily tested for proper operation. Many applications need to demonstrate sensor ...
