What is this unit for?
The ComfoFond-L Q is a fluid-driven ground-source heat exchanger
(also known as a subsoil heat exchanger) which uses ground heat
to preheat or cool outdoor air as required before it is supplied to the
dwelling.
Operating principles
The system comprises a number of components, including a
ComfoAir Q heat recovery unit, a ComfoFond-L Q and ducting.
These devices are controlled using the ComfoAir Q operating panel.

ComfoAir Q.
Brine loop pipes are laid in the ground and connected to the dwelling.
In the winter the cold outdoor air is preheated, ensuring the ventilation
system continues to operate effectively even at low temperatures. In
the summer the warm outdoor air is precooled. The ComfoFond-L
Q is specially developed to operate in combination with a Zehnder
ventilation system of type ComfoAir Q with Option Box.
Operation
The ComfoFond-L Q is controlled by the ComfoAir Q to which
it is connected. This works entirely automated based on the set
temperature profile of the ComfoAir Q.
Maintenance
The ComfoFond-L Q should be inspected and cleaned annually by
a specialist. To ensure a hassle-free lifespan for your ComfoFond-L
Q, we recommend you to take out a service agreement with a
specialist company.
