REQUIREMENT ТO THE FRESH AIR IN THE CONGREGATION ROOM

Abstract

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.
