The condensation drains of the
ComfoFond-L and the ComfoAir Luxe
must always be connected with a siphon.
4.4 Connecting the brine loop
(terrestrial heat collector)
Insulate all brine loop pipes (C) of the brine loop.
This prevents the formation of condensation on
the outside of the brine loop.
The ComfoFond-L uses a terrestrial heat
collector which extracts heat from the ground
and transfers this to the air that flows through
the ComfoFond-L. The terrestrial heat collector
is formed by a PE pipe. The length of the pipe is
subject to local conditions, such as the type of
ground and the ground water level. Solid ground
contains more energy that loose ground. If
the pipe is below ground water level, then
substantial quantities of energy can be
extracted at the base.
The pipe must be horizontally positioned in the
ground (more or less) at an ideal depth of 1,2 to
1,6 metres.
When calculating the length of the pipe, the
actual length for the calculation is the length
that is physically in the ground. The length
inside the house has no further effect on the
energy that the system can extract. The required
pipe length for sandy soil is twice as long.
The correct length of pipe can be determined
using the ComfoFond-L specifications.
Zehnder has special software available for
calculating the required pipe length.
The pipe can be laid in any random form.
The preferred situation is to lay the pipe in the
ground around the house and keep the length
inside the house to a minimum. In order to
increase the efficiency, a minimum distance of
60 cm between any loops in the pipe is advised.
In order to protect the water pipes from freezing,
the pipe must be at least 1 meter away from the
water pipes present in the ground.
Use an adaptor to connect one end of the PE
pipe to the brine connection inlet (A) of the
ComfoFond-L.
Use an adaptor to connect the other end of the
PE pipe to the brine connection outlet (B) of the
ComfoFond-L.
Both connections are ¾’ conical male-threaded.
An installation report has been included at
the rear of this manual which can be used to
note the details of the brine loop laid.
