What should be monitored to ensure effective heat exchange in an ERV?

Monitoring the airflow rates of both incoming and outgoing air is essential for ensuring effective heat exchange in an Energy Recovery Ventilator (ERV). The primary purpose of an ERV is to improve indoor air quality while conserving energy by transferring heat and moisture between incoming fresh air and outgoing stale air.

When the airflow rates are balanced, the system can achieve optimal performance, facilitating a more efficient heat exchange process. If the airflow rates are not correctly calibrated, it can lead to inadequate energy recovery, increased energy costs, and discomfort in the indoor environment. This balance also helps prevent issues like stale air buildup or excessive humidity, ensuring that both ventilation and energy efficiency goals are met.

Understanding airflow dynamics allows for proper system adjustments, including fan speed settings, duct design considerations, and other operational parameters that impact the overall effectiveness of the ERV.
