Energy recovery wheel
Daikin McQuay introduces an energy recovery wheel option for Rebel rooftop units. This energy recovery option makes the units more efficient, especially for applications requiring large amounts of ventilated air. The energy recovery wheel option recovers approximately 75% of energy from the exhaust air stream. As the wheel rotates, outside air is drawn across one-half of the wheel while exhaust air is drawn across the other half, transferring sensible and latent energy between the ventilation and exhaust air streams. Free heat and humidity are recovered during winter months while free cooling and dehumidification occur during the summer months. Easy, slide-out accessibility to the wheel is provided, simplifying service and cleaning for long-term, efficient wheel operation. The units also exceed ASHRAE Standard 90.1 requirements for energy recovery.
