| Abstract |
Indoor Air Quality has been significantly degraded due to the improvement of the airtightness of residential and commercial combined high-rise apartment buildings. In order to handle the problems related to insufficient ventilation, the application of mechanical ventilation system is required in detached residences or apartments in the country. As an alternative, air-to-air heat recovery ventilators are used at initial stage for energy conservation using waste heat recovery and the improvement of IAQ in high-rise apartments, currently being more widely used even in apartments and detached residences. Due to this trend, relevant institutes and organizations are making standards for the evaluation of HRV(Heat Recovery Ventilator) performance, but research related to the evaluation of HRV performance are not sufficiently done in this circumstance before applying in real buildings. Therefore, the purpose of this study is to compare and evaluate international and domestic standards for the evaluation of HRV performance, and to provide guideline for the adequate selection of effective HRV by evaluating the performance synthetically in terms of major items. |
