EXPERIMENTAL MEASUREMENTS OF A CARBON DIOXIDE CONCENTRATION FOR DETERMINING OF A VENTILATION INTENSITY IN A ROOM AT PULSING MODE

Air distribution by interaction of counter non coaxial air jets at pulsing mode has
been considered. Dynamic parameters of air flow that is created due to interaction
of counter non coaxial flat air jets at their leakage at pulsing mode and creation
of dynamic indoor climate in a room has been determined. This paper is aimed
to develop a methodology for determining the intensity of ventilation of indoor
premises based on the experimental measurements of the concentration of carbon
dioxide. Using experimental measurements and the knowledge gained in the study
of this issue, in the work the method for intensity ventilation determining
of the indoor premises was developed on the basis of the measured values of carbon
dioxide which was verified also by another experimental measurements.
The resulting values of ventilation intensity rate obtained by calculation from
the measured values of carbon dioxide were compared with the results of calculations
executed according to the laws and standards, valid in Slovakia. Based
on measured values of carbon dioxide concentrations a method for calculation
of the ventilation intensity was developed and compared with the methods used
in Slovakia.
