HOW IT WORKS ?

An earth-air heat exchanger (EAHX) ELIXAIR® is based on an underground network of pipes that form an earth-to-air heat exchanger. Fresh air circulates through these pipes, where it is naturally preheated in winter and cooled in summer. This system significantly improves drainage ventilation systems by reducing temperature-related issues, such as condensation or moisture buildup. By integrating this solution, businesses benefit from sustainable construction practices that enhance building efficiency.

Key Functions and Benefits

ELIXAIR® functions as a passive climate control system, reducing the need for mechanical heating and cooling. Properly sized according to required fresh air flow, it can achieve up to 30% heating savings in colder months while covering up to 100% of cooling needs in warm periods. Unlike traditional ventilation fixtures, ELIXAIR® helps prevent slow airflow, clogs, and blockages that can arise in conventional systems.

THERMAL PERFORMANCES

In winter: in-out average temperature difference = 7 to 12°C

In summer: in-out average temperature difference = 7 to 16°C

Installation Considerations

To maximize its effectiveness, ELIXAIR® must be buried at an optimal depth of at least two meters, ensuring proper air-to-ground heat exchange. This depth helps mitigate common issues like slow heat transfer or uneven temperature regulation. Proper placement near key building elements such as walls, larger ventilation ducts, and air distribution units ensures the system's full functionality.

Incorporating ELIXAIR® into a heating and cooling system is an investment in efficiency, cost savings, and environmental responsibility. By utilizing geothermal technology, businesses can achieve superior thermal performance, improving comfort while reducing overall energy consumption.
