Understanding Heat Recovery Ventilation

Heat Recovery Ventilation operates through the controlled exchange of thermal energy between two separate airflows. As indoor air is expelled, it passes through a heat exchanger, which captures the heat before the air is discharged outdoors. Simultaneously, cooler external air is drawn in, warmed by the recovered heat, and then circulated within the building.

This process is designed to ensure that fresh air enters the space while maintaining a comfortable indoor temperature. The system functions effectively without mixing the two air streams, preserving air quality. Its components, such as the heat exchanger, filters, and fans, work in unison to regulate airflow and maximise efficiency.

How Hrv Heat Recovery Works?

Hrv heat recovery centres around the efficient transfer of thermal energy between outgoing and incoming airflows. This process occurs in the heat exchanger, which captures heat from the stale air being expelled from the building and uses it to warm the incoming fresh air. By keeping the airflows separate, the system ensures that the quality of the fresh air is maintained.

The operation is facilitated by fans that regulate the movement of air, ensuring consistent ventilation and temperature control throughout the building. This mechanism reduces reliance on traditional heating systems by reusing the warmth already present within the indoor environment.
