| Abstract |
Recently, energy recovery ventilators (ERVs) have been installed for energy saving in many multi-residential buildings in Korea. The performance of the heat exchanger of an ERV is analyzed in this study under specific indoor and outdoor conditions in a test-cell measurement. However, the performance of the heat exchanger varies according to the indoor and outdoor condition. In this study, the performance of energy recovery of the ventilation system was therefore analyzed in actual weather conditions using field measurement. Experiments were conducted under winter conditions in a multi-residential building for 20 days. Based on the measurement results, the characteristics of sensible heat and latent heat exchange rates were analyzed. |
