요약2 |
This study aimed to confirm the variation by the elapsed replacement time of ventilation filter and decreasing effects of CO2 concentration by a ventilation filter replacement. Field tests were carried out on the middle school classroom. Measurement results in air volume have shown that the amount of supply and exhaust air has been increased by the filter replacement, consequently decreasing CO2 Concentration. After 4 month of filter replacement, air volume decreased, but CO2 concentration was similar to that immediately after replacement. This is because the distribution of indoor air flow is different because EHP is operated from heating to cooling. Thus, regular filter replacements may help keep the classroom in a comfortable space. |
