Energy Recovery Introduction: Compared to HRV (Heat Recovery Ventilator), ERV can also
transfer humidity and recover energy from that humidity. ERV can exchange energy
between “stale” EA and “fresh” OA, by transferring heat and moisture into the incoming cold
air, and pre-cooling and reducing the humidity of the incoming hot air. This helps maintain a
fresh environment even when the heating or cooling system is not operating.
