Abstract

Fine dust particles are deposited in the human body through various mechanisms, leading to adverse health effects. The behavior of these particles varies with their size. This study examines the performance and filtration efficiency of heat recovery ventilators (HRVs) with filters in residential buildings through field measurements. By analyzing particle removal efficiency, it was found that operating a ventilator with a Case 1 (40%) filter increased indoor fine dust concentration compared to when the ventilator was off. Conversely, filters in Case 2 (90%) and Case 3 (99.5%) effectively controlled fine dust concentration. Performance degradation was observed as follows: Case 1: 39.2%, Case 2: 15.1%, and Case 3: 13.5%. As filtration efficiency increases there is a corresponding loss in ventilation rate by the HRV. Therefore when selecting filters for HRV, it is necessary to consider both ventilation rate and filtration efficiency simultaneously.
