Air-to-Air Heat Exchangers: Saving Energy and Improving Indoor Air Quality

摘要

Some houses currently built have substantially reduced air infiltration rates to conserve heating and cooling energy use. Indoor air quality problems associated with this large reduction in ventilation air have become apparent. The paper describes the use of mechanical ventilation coupled with heat recovery devices in residential buildings to maintain acceptable indoor air quality and conserve energy. Estimates of energy and peak power savings are given. (ERA citation 04:050269)
