Purpose: Energy recovery ventilator(ERV) has provided fresh air with energy efficiency. However, ERV can be stop for cold outdoor temperature in the winter seasons. Cold temperature in supply air has made not only freezing(condensation) in the ERV but also impeding the thermal comfort. Therefore, this paper produces an alternative for ERV system in inner return mode with optimal operation strategies. Method: For verifying the inner return ERV, there were three sector based building and chamber experiments. First, CO₂ of representative of pollutant was criterion for maintaining the IAQ. We emitted CO₂ to 15liter/h –person. Power consumption of ventilator and heat loss through ventilation collected in winter season because inner return mode operated made different heat exchange. Third, freezing(condensation) concerned all of cases in chamber experiments. Result: CO₂ concentration exceeded 1,000ppm in case3(OA50+RA50). Power consumption of ventilator increased because of using inner return mode. On the other hand, inner return modes decreased heat loss through ventilation up to 47.1% in comparison with baseline mode. Freezing occurred in baseline model in –15℃, -20℃(OA side, EA side). Although lower outdoor temperature, inner return mode case3(OA50+RA50) does not founded freezing and condensation. We found weakness point of the inside (lowest temperature). All things considered, inner return mode take has advantage of merit during winter season.
