1. Introduction and safety
What is this unit for?
The ComfoFond-L is a brine geothermal
exchanger, also known as a terrestrial heat
exchanger. The ComfoFond-L heats or cools
the outside air using terrestrial heat. The heated
or cooled outside air is then supplied into the
dwelling.
Function
1. Brine loop pipes;
2. ComfoFond-L;
3. ComfoAir Luxe.
Brine loop pipes are laid in the ground and
connected to the dwelling. In the winter the cold
outside air is preheated, ensuring the ventilation
system continues to operate effectively even at
low temperatures. In the summer the warm
outside air is precooled.
The ComfoFond-L is specially developed to
operate in combination with a Zehnder
ventilation system of type ComfoAir 350 Luxe or
ComfoAir 550 Luxe. The required pump control
for the ComfoFond-L is integrated in this
ventilation system as standard.
The ventilation unit installation manual covers
in greater detail ventilation issues and how the
ventilation system works. A copy of this manual
can be obtained from the suppelier.
