  • Recently, regulation of ventilator installation and its details has been revised and the establishment of heat recovery ventilator in newly built apartments has been obligated. This study was done to offer the method of operation and design of heat recovery ventilator to save energy by measuring its efficiency and comparing with the results of experiment. This paper confirmed that it is desirable to operate heat recovery ventilator by using "by-pass mode" within $60{\sim}80%$ scope of the difference indoor absolute humidity in spring and autumn and outdoor absolute humidity and heat recovery ventilator of energy saving effect is better than constant air volume system.

  • 본 연구는 공동주택에 적용되고 있는 환기장치를 선정하고 환기장치의 에너지특성 분석과 에너지저감을 목적으로 시뮬레이션 프로그램 (ECO2)을 이용하여 환기장치 별 에너지성능평가를 수행하였으며, 아래와 같이 결과를 도출하였다. 공동주택을 대상으로 환기장치 별 에너지 효율등급평가 기준에 따른 소비량을 수행하고자 하였다. 또한 단지별 에너지소비량과 비교 검토 결과를 통하여 현재 우리나라에서 공동주택에 적용하고 있는 환기장치별 에너지 소비량 실태를 파악하였다. 중부지방의 84type, 한 개동을 대상으로 시뮬레이션한 결과, 자연환기장치의 등급용 1차에너지소요량 값은 $159.9kWh/m^2yr$, 전열교환환기장치 $161kWh/m^2yr$, 바닥환기장치 $179.7kWh/m^2yr$로 계산 되었다. 위 시뮬레이션 결과를 공동주택의 실제 현장자료로 검증하였으며, 환기장치별 에너지소요량에 대한 비율로 비교해본 결과, 전열교환환기방식이 자연환기방식에 비해 -1~6% 적은 값을 보였으며, 바닥배관환기방식이 자연환기방식에 비해 약 10~20% 더 많은 1차에너지소요량이 나타났다. 환기장치의 팬동력과 열회수효율에 따라 에너지소요량의 난방과 환기 값이 변화하며, 향후 기계환기장치의 효율화 및 최적화가 필요하다고 판단된다.

  • Heat-recovery ventilators are being adopted in most newly built apartment houses for energy reduction and indoor environment improvement. In winter, however, the dew condensation resulting from the difference between the indoor and outdoor temperatures may reduce the ventilator's performance and threaten the health of indoor residents. This study analyzes the occurrence of dew condensation according to the ventilator's operational conditions and the changes of temperature and products. The experimental results show that condensations is formed at $26^{\circ}C$ and 60%R.H, which is an unfavorable climatic condition, and when the damper is not closed tightly. Therefore it is important to ensure damper performance to prevent back flow.

  • ERV system has installed in almost newly constructed residential building in Korea. Heat recovery features of ERV can be possible to decrease the heating and cooling load caused by ventilation. However, in case of the outdoor condition is favorable to control the indoor air, the heat recovery function of ERV does more harm than good in term of cooling load. In this study, the ERV with economizer cycle control for residential building is suggested and the performance of the suggested system will be analyzed using TRNSYS.

  • Maintaining an IAQ with fresh in school building is very important because the good IAQ can be possible to improve the academic performance. Since school buildings are very dense and require a lot of fresh air, the need for ERV(Energy Recovery Ventilator) has become obvious. While opening a window does provide ventilation, the building's heat and humidity will then be lost in the winter and gained in the summer, both of which are undesirable for the indoor climate and for energy efficiency. ERV technology offers an optimal solution: fresh air, better climate control and energy efficiency. However, when the outdoor air condition is favorable to control the indoor environment such as spring and autum in Korea, heat exchange in ERV would rather increase the cooling load than diminish. Economizer cycle control which using the outdoor air in controlling the indoor thermal environment has many benefit in terms of energy saving and IAQ control. In this study, the ERV with economizer cycle control will be suggested. And then the system control characteristics and energy saving effect will be analyzed through the TRSNSYS Simulation.
