Air routing with hoses
the total length of hoses on the air
inlet and discharge side must not
exceed 8 m. never incorporate more
than four 90° bends.
the hose will tend to sag because
of its flexibility; therefore secure
it in approx. 1 m intervals. special
hoses are used to route the inlet
air from the outside to the heat
pump and discharge air from the
heat pump to the outdoors. these
hoses are highly flexible, thermally
insulated and are self-extinguishing
in case of fire. thermally insulated
hoses are available in 3 m lengths
(li Ø 400 mm).
Air routing with air ducts
with air routes longer than 8 m,
air ducts can also be connected to
the heat pump. the cross-section of
the air duct varies according to the
air flow rate and according to the
externally prevailing, static pressure
differential of the heat pump. to
reduce the transfer of structure-borne
noise in the building, install an air
hose or canvas flange between the
heat pump and the air ducts. when
sizing air ducts and grilles, observe
the external pressure of the fan.
Special features
if the heat pump is installed in an
enclosed room containing combustion
appliance that takes its a combustion
air directly from the room (open flue
operation), then a ventilation aperture
to the installation location with 250
cm² diameter is required, to prevent
the heat pump from influencing the
operation of the gas or oil burner.
without this additional ventilation,
small, unavoidable leakages on the
air inlet side, e.g. at hose connectors
or at the heat pump, will reduce the
air pressure in the enclosed room to
unacceptable levels.
