Energy conservation potential by optimization of air flow rate of mechanical ventilation.

Number: pap. 3173

Author(s) : GU B., SCHMID J., SCHMIDT M.

Summary

The indoor air quality in buildings is ensured by mechanical ventilation with a sufficient outside air flow rate according to national or European regulations. The sufficient outside air flow rate but in traditional view increases the heat demand of buildings and the higher the air flow rate the higher is the energy demand; hence man is likely to reduce the air flow rate in order to save energy. The consideration of this point is that mechanical ventilation systems with constant volume rate are replaced by ones with variable volume rates. This investigation shows significant energy conservation potential by optimization of air flow rate. A typical office room for two occupants in an EnEV 2009 and WSchV 82 building is used as investigated model in the study respectively. The software TRNSYS is used for the assessment of annual energy demand for heating and cooling of the room.
