Indoor air quality is a critical factor in the classroom due to high people concentration in a
unique space. Indoor air pollutant might increase the chance of both long and short-term …

The purpose of the paper is to analyse air humidity in classrooms with stack ventilation.
Based on experimental research, new humidity models in classrooms were developed …

Air distribution systems are essential for controlling indoor airborne cross-infection risks.
However, there is no consensus on the most effective system. This study compares the …

Schools are recognized as high-risk spaces in airborne infectious disease transmission due
