Abstract |
Recently, almost all the high-rise building have applied mechanical ventilation system because it is hard to apply natural ventilation system by reason of high wind pressure and pressure difference of indoor-outdoor by the building height. The purpose of this study is to evaluate the characteristics of indoor contamination levels and to decrease energy consumption in the high-rise residential building according to the various ventilation strategies of mechanical ventilation system. It made investigation current state and problems of ventilation system in high-rise resident building, and prospected of the alternative ventilation system using sensor based CO2-DCV (Demand Controlled Ventilation)system equiped heat recovery ventilator on each house hold. As a result, sensor based CO2-DCV system equiped heat recovery ventilator on each house hold is proper to maintain indoor air quality and to decrease energy consumption for ventilation load. And, the energy consumption decrease rate is approximately 19 percent for one year, 5 percent for cooling season and 20 for heating season applied CO2-DCV system equiped heat recovery ventilator on each house hold. |
