공동주택 발코니공간을 이용한 하이브리드 환기시스템의 성능평가

The purpose of this paper was to evaluate the performance of hybrid ventilation system using the balcony space to solve the problem that mechanical ventilation systems have. The results of the simulation(TRNSYS and TRNFLOW) revealed that hybrid system was better than the constant mechanical system in indoor air quality and energy consumption. However, in mechanical ventilation mode, the two systems showed the similar in the concentration of pollutant. Also, hybrid ventilation method maintained the indoor thermal condition constantly during cooling and heating seasons. Regard to the energy consumption, the hybrid system could reduce 37% of heating, cooling and ventilation energy compared to constant airflow mechanical system. Therefore, the hybrid ventilation system using the balcony space in apartment housing would provide better comforts to the occupants and lower the energy consumption compared to the constant airflow ventilation system.
