Demand Controlled Ventilation Systems : CO2 Controlled Ventilation Systems

TL;DRAbstract

The subject of the project was a research about the CO2-based demand controlled ventilation. 
\nThe thesis starts with literature review. The first chapter provides clear understanding of the main concept of CO2-based DCV, required ventilation rates and CO2 differential, information about human breathing and the way it influences the air quality in the interior of the building. In the second chapter there is main benefits of demand controlled ventilation.
\nThe third chapter provides CO2 measurement technology. There are two types of sensors to measure CO2 concentration with help of the IR absorption method. The first is non-dispersive infrared (NDIR) absorption sensor and the second is photo-acoustic sensor. In the next chapters are given information about application of demand controlled ventilation, design considerations for demand controlled ventilation, energy efficiency and design example of demand controlled ventilation.
\nDCV system controls the amount of outdoor fr
