An Energy Recovery Ventilator (ERV) is a mechanical ventilation system that supplies outdoor air and exhausts stale indoor air while transferring heat and, in enthalpy recovery systems, moisture between the two air streams.
This energy exchange helps reduce the heating or cooling load associated with outdoor air ventilation. An ERV also supports indoor air quality by providing a controlled supply of fresh air. Its actual performance depends on the exchanger design, airflow, climate conditions, filtration, and system installation.
