Abstract

School’s indoor air quality (IAQ) is very important as it can affect student’s learning abilities and lead to health issues. Therefore, indoor air quality, and in particular the CO2 concentration, was monitored on a daily basis from mid-November till the end of December 2017, by using several low-cost instruments. The measuring was performed in the physics classroom of a grammar school in Rijeka, Croatia. Detailed CO2 generation rates, air exchange rates, and ventilation rates are calculated and reported in this work, from the experimentally obtained data. Very high concentrations of over 4.000 ppm were recorded, indicating that ventilation rates are far below 5 Ls-1 per person, which is the lowest recommended value of ventilation rate according to the European standard EN 13779. The experimentally obtained data are compared with the theoretical models and a strong correlation are achieved. This is one of the first comprehensive studies of this kind in Croatia; therefore, we hope that it will stimulate interest between health workers, scientists, and school management to implement indoor air quality monitoring practices and perhaps introduce automated ventilation systems in classrooms for the benefit of students’ health and their learning abilities.

克罗地亚里耶卡一所高中教室的室内空气质量(二氧化碳浓度上升导致教室生病)
学校的室内空气质量(IAQ)非常重要,因为它会影响学生的学习能力并导致健康问题。因此,从2017年11月中旬到12月底,通过使用几种低成本仪器,每天监测室内空气质量,特别是二氧化碳浓度。测量是在克罗地亚里耶卡一所文法学校的物理教室里进行的。在这项工作中,根据实验获得的数据,计算并报告了详细的二氧化碳生成率、空气交换率和通风率。记录了超过4.000 ppm的非常高的浓度,表明通风率远远低于每人5 l -1,这是根据欧洲标准EN 13779建议的最低通风率值。将实验数据与理论模型进行了比较,发现两者具有较强的相关性。这是克罗地亚首个此类综合研究之一;因此,我们希望它能激发卫生工作者、科学家和学校管理人员对实施室内空气质量监测实践的兴趣,并可能在教室中引入自动通风系统,以有利于学生的健康和学习能力。
