Визначення продуктивності вентиляції приміщення у змінному режимі на основі eкспериментальних досліджень концентрації СО2

Abstract

In this paper, the distribution of air by the interaction of flat non-equivalent counter jets in the alternating regime is considered. The dynamic parameters of the air flow generated by the interaction of flat non-equivalent counter jets with their flow in the alternating mode with the creation of a dynamic microclimate in the room are determined. The purpose of this article is to improve the methodology for determining the efficiency of ventilation based on experimental measurements of carbon dioxide concentration. With the help of experimental measurements and knowledge obtained in the study of this problem, a method for determining the ventilation efficiency of a room on the basis of measured values of carbon dioxide was developed in the work, which was also verified by other experimental measurements. The value of the ventilation efficiency obtained as a result of the calculation of measured values of carbon dioxide, was compared with the results of calculations performed in accordance with current legal norms and regulations. On the basis of comparison of results, one of the methods for calculating the efficiency of ventilation was developed, the results of which proved to be as close as possible to the results obtained by the method of determining the efficiency of ventilation in the room on the basis of measured values of carbon dioxide.
