Nibe AMB 30, Installer Manual

Page: 14 / 52

General
Pipe installation must be carried out in accordance with
current norms and directives.
Because AMB 30 is not equipped with shut off valves,
drain valve and vent valve these must be installed to
facilitate any future servicing.
NOTE
If AMB 30 is installed in an existing system any
level vessel on the brine side must be replaced
with a pressure expansion vessel.
NOTE
The pipe work must be flushed before AMB
30 is connected, so that any contaminants do
not damage the components parts.

System diagram
AMB 30 is a heat absorbing air collector module which
is an accessory for NIBE F1345. AMB 30 is connected
to F1345 only (outdoor air operation) or in combination
with a ground source/horizontal ground collector (hy-
brid operation) to supply the heat pump with renew-
able energy. AMB 30 utilises the outdoor air so there
is no need for bore holes or coils in the ground.
AMB 30 is in principle an element that exchanges the
air’s energy with a liquid system using an axial fan and
control system. The fan has two speeds that either
change automatically at the selected ambient temper-
ature or is manually set to high/low speed.
The unit’s control system is connected to a control unit
(BCU 30) where all the settings and monitoring occurs.
This control unit is installed indoors. The control system
manages all functions such as fan operation, defrosting,
selection of operating mode, and stopping the com-
pressor during defrosting and at low ambient temper-
ature.
The material has been chosen for a long service life and
is designed to withstand demanding outdoor condi-
tions.
Outdoor air operation mode
During outdoor air operation AMB 30 only uses the
outdoor air as a heat source and operation is permitted
down to an outdoor air temperature of approx -7
ᩊ C.
Outgoing brine from F1345 is connected directly to
the air module. When the ambient temperature is
lower than the dimensioned balance temperature (the
lowest temperature where the heat pump can manage
all the heating) additional heat must be accessible to
supplement the heat pump.
M
The brine, heating medium and domestic hot water side must
be fitted with the necessary safety equipment in accordance with
the applicable regulations.
