NIBE™ F1155Chapter 1 | Important information6

F1155 – An excellent choice
F1155 is part of a new generation of heat pumps, which have been intro-
duced to supply your home with inexpensive and environmentally friendly
heating and/or cooling. Heat production is safe and economical with in-
tegrated immersion heater, circulation pumps and control system.
The heat pump can be connected to an optional low temperature heat
distribution system. e.g. radiators, convectors or under floor heating. It is
also prepared for connection to several different products and accessories,
e.g. hot water heater, ventilation recovery, pool, free cooling and climate
systems with different temperatures.
For F1155-6 1x230V or 3x230V a 4.5 kW immersion heater can be connec-
ted automatically if anything unforeseen should occur or as back-up oper-
ation (then 3.5 kW).
For F1155-6 3x400V a 6.5 kW immersion heater can be connected auto-
matically if anything unforeseen should occur or as back-up operation
(then 3.5 kW).
For F1155-16 3x400V a 7 kW immersion heater can be connected auto-
matically if anything unforeseen should occur or as back-up operation
(then 6 kW).
F1155 is equipped with a control computer for good comfort, good eco-
nomy and safe operation. Clear information about status, operation time
and all temperatures in the heat pump are shown on the large and easy
to read display. This means, for example, that external unit thermometers
are not necessary.
Excellent properties for F1155:
႑Inverter controlled compressor
The heat pump has an inverter controlled compressor that automatically
adapts itself optimally and economically to your house and supplies your
installation with renewable energy.
႑Scheduling the indoor comfort and hot water
Heating and hot water as well as cooling and ventilation in some cases,
can be scheduled for each day of the week or for longer periods (vaca-
tion).
႑Display with user instructions
The heat pump has a large display with easy-to-understand menus that
facilitate setting a comfortable climate.
႑Simple troubleshooting
In the event of a fault, the heat pump display shows what happened
and the actions to be taken.

NIBE™ F1155Chapter 2 | The heat pump – the heart of the house8

Heat pump function
A heat pump can use stored solar energy from rock, ground or water in
order to heat a property. The conversion of stored energy in nature to
property heating occurs in three different circuits. In the brine circuit, (1)
, free heat energy is retrieved from the surroundings and transported to
the heat pump. In the refrigerant circuit, (2) , the heat pump increases the
retrieved heat's low temperature to a high temperature. In the heating
medium circuit, (3) , the heat is distributed around the house.
Brine circuit
In a hose, collector, an anti-freeze liquid, brine, circulates from the heat
pump out to the heat source (rock/ground/lake). The energy from the
heat source is stored by it heating the brine a few degrees, from about
–3°C to about 0 °C.
A
The collector then routes the brine to the heat pump’s evaporator. Here,
the brine releases heat energy and the temperature drops a few degrees.
The liquid then returns to the heat source to retrieve energy again.
B
Refrigerant circuit
Another liquid circulates in a closed system in the heat pump, a refrigerant,
which also passes the evaporator. The refrigerant has a very low boiling
point. In the evaporator the refrigerant receives the heat energy from the
brine and starts to boil.
C
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas's temperature increases considerably, from approx. 5ᩊC to
approx. 100 ᩊC.
D
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heating system in the house,
whereupon the gas is cooled and condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
F
Heat medium circuit
The heating energy that the refrigerant releases in the condenser is re-
trieved by the heat pump's boiler section.
G
The heating medium circulates in a closed system and transports the heated
water's heat energy to the house water heater and radiators/heating coils.
H
The temperatures are only examples and may vary between different installations and
time of year.

External information
When the heat pump door is closed, information can be received via an
information window and a status lamp.

Information window
The information window shows part of the display that is on the display
unit (located behind the door to the heat pump). The information window
can display different type of information, e.g. temperatures, clock, etc.
You determine what is to be displayed in the information window. Your
own combination of information is entered using the display unit. This
information is specific to the information window and disappears when
the heat pump door is opened.
Instructions on how to set the information window can be found on page
61.
Status lamp
The status lamp indicates the status of the heat pump: continuous green
light during normal function, continuous yellow light during activated
emergency mode or continuous red light in the event of a deployed alarm.
Alarm management is described on page 68.
