Technologies in balanced ventilation systems to maintain optimal performance in energy and comfort

Measurements of the installed base of balanced ventilation systems in houses often show that optimal performance is not achieved. The installed base however, is a mix of various generations of units that have been developed over the years, starting in 1980. As a result, energy benefit and perceived comfort for residents is underestimated. Since 2015, improved knowledge has led to new technologies that have been implemented in the newest generation balanced ventilation units. In the following paragraphs, seven technologies are described that guarantee the fresh air flow as well as the balance between the supply and return air stream. This ensures a constant refreshment, an optimal energy benefit of recovery and resultingly a better comfort of the supplied fresh air flow for occupants.
