REQUIREMENT ТO THE FRESH AIR IN THE CONGREGATION ROOM

We have more kinds of congregation rooms. When building of these spaces must
to supervise, among other the requirements also the quality of the indoor air
should be considered. In our article we are engaged analysis of ventilation
in church of the 13th century. The aim is analyzing of produce of pollutant emissions
from persons in the room. One of measurable the pollutant is carbon dioxide,
which is produced by persons. Beside the respiration, the person produces
other pollutants, such as odor and others. On the basis of experimental measurements
the concentration of carbon dioxide produced by person, currently we know
calculate how much air exchange is required for the room. The concentration
of carbon dioxide has be smaller how 1,000 ppm and maximum up to 1,500 ppm.
Already above the value of 1,000 ppm causes to decrease the concentration
to perception for people. The aim of the paper is to determine the methodology
for calculating the intensity of ventilation rate in the room. It is need to maintain
the required air quality. Calculated ventilation rate should optimize investment
and operating costs of ventilation equipment. In the work there is carried out
analysis of calculation methods to determine the ventilation rate. It is processed
the methodology for calculating the ventilation rate of room, there are used
the measured values of concentrations of carbon dioxide. Values of concentrations
of carbon dioxide and ventilation rate there are verified by experimental
measurements. The methodology is selected for calculating ventilation rate applicable
in to Slovakia.
