| 요약2 | This study estimates ventilation efficiency for apartment using solar radiation in order to improve energy savings and indoor air environment. Field measurements were performed in a full-scale mock-up model. A solar collection device and ordinary device for natural ventilation were installed in each room. Temperature and airflow velocity were monitored in each five minutes. Solar radiation and daylight illuminance were also measured. The concentration of indoor air for two conditions was monitored using a multi-gas monitor and tracer gas. The air change rates per hour(ACH) under the conditions were computed based on the concentrations. The air change rates per hour (ACH) using solar radiation exceeded the required air change rate per hour was linearly proportional to the solar radiation. The ventilation device using solar radiation contributed to provide better thermal environment with energy savings. From the result of ventilation efficiency prediction for the 85㎡ area of practical residential building by CFD simulation, it was found that average age of air was 90.3min, nominal time constant was 82.9min. So total average ventilation efficiency was 0.918, this value means about 92% of indoor air could be mixed. |
