The video shows the VENTIFLEX® PLUS mechanical ventilation with heat recovery co-operating with Ground – Therm’s ground-based heat exchanger in an energy-efficient building.
As the temperature of the ground below 3m is practically constant, it substantially reduces ambient air temperature fluctuations.It therefore provides space conditioning throughout the year, with the incoming air being heated in the winter and cooled in the summer by means of earth coupling.
Ground Heat Exchangers (GWCs), which we call ecological air-conditioning, are a perfect complement to an efficient ventilation system.In winter, they let you use the heat from the ground to preheat the air supplied to your home.
In the summer, this allows the air to cool effectively, providing a comfortable indoor climate. GWC do not dry out the air as traditional air conditioners do, but provide the right humidity. In addition, the GWC operation is almost free – the air is forced through the recuperator fans, which is the heart of the entire system.
