Recycle Building Energy with Airxchange Energy Recovery Wheels

Building codes require outdoor air ventilation to control building indoor air quality. The outdoor air can represent up to 50% or more of the total HVAC building load.  An energy recovery wheel recycles energy from the normally exhausted building air to pre-condition incoming ventilation air.  By recycling 70 – 80% of the total energy contained in the exhaust air, energy recovery wheels lower total HVAC energy usage.

Energy recovery wheels offer a highly efficient alternative to condition the outdoor air as compared to a typical vapor compression system (roof-top DX system). Combing the two technologies can increase your total system efficiency up to 40%.

Shifting the outdoor air ventilation load to the wheel reduces the demand on traditional HVAC equipment, allowing the now smaller wheel based HVAC equipment to operate more efficiently.

“We have realized a 10 to 15% reduction in our total building energy usage while maintaining the indoor air quality that we need for our customers and associates. With this new technology, the cooling that is normally wasted, is now captured and transferred back into the building.”
