Introduction to Heat Recovery Ventilation Units
Ventilating a building is necessary to maintain a healthy and comfortable indoor environment, by removing pollutants, moisture and allergens. This eradicates condensation, prohibits mould growth and discourages the spread of bacteria, viruses and dust mites.
Stale air is extracted through the Heat Recovery Ventilation Unit, while fresh air is brought in through a separate air grill. The fresh air is filtered and purified. It then passes through the heat exchanger where the energy of the extracted air is transferred to the incoming fresh air, warming it during cold weather and cooling it in warmer periods. The fresh and exhausted air is separated by a specially treated membrane so that there is no mixing of airflows. Only fresh air enters the room.
