Определить расчетом уменьшение концентрации углекислого газа при периодическом проветривании весьма затруднительно. Проведено экспериментальное исследование для оценки влияния проветривания в холодный период года на качество воздуха и параметры микроклимата. Объект исследования – учебный кабинет площадью 55.6 м2. В первый день исследования проветривание проводилось перед началом занятий и во время перерывов. Во второй и третий дни режим проветривания определялся обучающимися и преподавателями. Измерение концентрации углекислого газа, температуры и относительной влажности воздуха производилось измерителем качества воздуха, установленным в центре помещения на высоте 1.5 м. В первый день требуемое качество воздуха было зафиксировано на протяжении 16 % учебного времени, допустимое и низкое на протяжении 47 и 37 % соответственно. При этом максимальная концентрация углекислого газа составила 2 639 ppm, и наблюдался неустойчивый тепловой режим с максимальным увеличением температуры на 4.7 °C за 45 мин занятия. Без контроля за режимом проветривания и при закрытой двери в кабинет во время занятий продолжительность учебного времени при низком качестве воздуха увеличилась в 2.2 раза, а максимальная концентрация углекислого газа была выше в 1.3 раза. </p></abstract><trans-abstract xml:lang="en"><p>Air quality and microclimate parameters in classrooms impact student health and academic performance. Calculate the precise reduction in carbon dioxide concentration achieved through periodic ventilation is challenging. Therefore, an experimental study was conducted to evaluate the effect of ventilation on air quality and microclimate parameters during the cold season. The research object was a classroom with an area of 55.6 m2. On the first day of the study, ventilation was implemented before the start of classes and during breaks. On the second and third days, the ventilation schedule was determined by the students and lecturers. Carbon dioxide concentration, air temperature and relative humidity were measured using an air quality meter positioned in the center of the room at a height of 1.5 meters. On the first day, the air quality met the required standard for 16% of the teaching time, while it was acceptable and low for 47 and 37% of the time, respectively. The maximum carbon dioxide concentration reached 2639 ppm, and an unstable thermal environment was observed, with a maximum temperature increase of 4.7 °C over a 45-minute class period. Without control over the ventilation schedule and with the classroom door closed during classes, the duration of study time with poor air quality increased by 2.2 times, and the maximum carbon dioxide concentration was 1.3 times higher.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вентиляция</kwd><kwd>качество воздуха</kwd><kwd>микроклимат</kwd><kwd>относительная влажность</kwd><kwd>температура</kwd><kwd>углекислый газ</kwd><kwd>учебный кабинет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ventilation</kwd><kwd>air quality</kwd><kwd>microclimate</kwd><kwd>relative humidity</kwd><kwd>temperature</kwd><kwd>carbon dioxide</kwd><kwd>classroom</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Денисихина Д.
