This study aimed to analyze the air flow rate, air leakage rate, heat exchange efficiency, and dust purification ability according to the filter class installed in the Heat-recovery ventilator. Pre-filter, H11, H12, and H13 were used and Heat-recovery ventilator was installed in the chamber and tested. Experimental results showed that the H13 filter had the smallest airflow reduction and high heat exchange efficiency, but the H12 filter showed the best performance as a result of comprehensive analysis of the dust purification ability and the heat exchange efficiency.   Keywords: Energy Recovery Ventilator; Filter Class; Heat Exchange Efficiency; Air Flow; Air leakage rate; Dust Purification Ability                                29 ZEMCH 2019 International Conference l Seoul, Korea
