| Abstract |
This study examines the influence of a heat recovery ventilator (HRV) on energy saving and improvement of indoor air quality (IAQ) in high-rise apartment buildings. Field measurements were performed in actual residential units of apartment complex during summer, and computer simulations were performed using the measurement data and standard weather data in Korea. Results indicate that the HRV was an effective contributor to improving IAQ with necessary ventilation rates and efficient energy savings. Validation between computer simulation and measurement results was acceptable under a lower significance level. Predicted and measured energy consumption for an entire year indicates that HRV effectively contributed to saving energy in winter due to the high temperature difference between outdoor and exhausted air. This study suggests that the HRV would be effectively applied in winter than summer when sensible heat is primarily exchanged in the HRV. |
