CO2 Study and dependancy of Ventilation Rate on CO2 Concentration-A Survey [ ]

This paper summarize the role of CO2 in ventilation systems. A survey also helped to study the current state of the art in Co2-based ventilation control with brief discussion of technology used, its reliability and how it is best used for energy saving. The control of outdoor air intake rates in mechanically ventilated buildings based on indoor carbon dioxide (CO2) levels, called CO2 demand controlled ventilation (DCV). This paper gives the overall view of actual energy saving potential, ventilation system features, building occupancy, how indoor air quality impacts to implement CO2 DCV. The report presents the art of review of CO2 technology and applications with its literature review. In addition specifications while using CO2 sensor are examined.
