Study on Indoor air Quality of a University Classroom in Northern Region—Illustrated by the Case of Dalian
Abstract: Indoor air quality not only affects the comfort and health of the human body, but also has a significant impact on indoor work and learning efficiency. The research assesses a certain university in Dalian, using MCH-383SD and TSI Dust Monitor to measure the air quality of classroom, with measuring items including CO2 concentration, tempera- ture, relative humidity and repairable particulate matter (PM10, PM2.5), which aims to explore the impact of CO2 con- centration factors and their impacts on students’ learning outcomes. The study concludes that the biggest factors affect- ing indoor air quality are exceeded indoor CO2 concentration, insufficient fresh air volume (per person) and over-crowded classroom. The continuous monitoring reflects that the increase of the indoor CO2 concentration is related to the number of people in the classroom and the ventilation condition. And the indoor CO2 concentration is much higher in heating period of winter than the concentration in autumn. Based on the premise of the feasibility, the paper proposed several new methods to improve the indoor air quality in college during winter.
