How Energy Recovery Ventilator Operate?
ERVs operate through a sophisticated heat exchange mechanism designed to maximize energy efficiency. Energy recovery ventilator begins as stale indoor air is expelled and fresh outdoor air is drawn into the system. A core component, the heat exchanger, plays a pivotal role by facilitating thermal energy transfer between the outgoing and incoming air streams.
During colder months, the outgoing warm air transfers its heat to the incoming cold air, pre-warming it before entering the indoor space. Conversely, in warmer months, the cooler outgoing air absorbs heat from the incoming warm air, effectively pre-cooling it.
Additionally, ERVs manage indoor humidity by allowing moisture to move between the air streams, helping to maintain balanced humidity levels. This dual function of heat and moisture transfer enhances indoor air quality and significantly reduces the energy demands on heating and cooling systems. The result is a more energy-efficient and comfortable indoor environment, making ERVs an attractive option for various building types.
