Chapter 2 | The heat pump – the heart of the house
NIBE™ F2040
An air/water heat pump can use the outdoor air to heat a property. The
conversion of the outdoor air's energy 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.

Outdoor air
The outdoor air is sucked into the heat pump.
The fan then routes the air to the heat pump’s evaporator. Here, the air releases
the heating energy to the refrigerant and the air's temperature drops. The
cold air is then blown out of the heat pump.
Refrigerant circuit
A gas 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 outdoor air and
starts to boil.
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 5 °C to approx. 80°C.
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.
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.
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is retrieved
by the climate system's water, heating medium, which is heated to 55 °C
(supply temperature).
The heating medium circulates in a closed system and transports the heated
water's heating energy to the house water heater and radiators/heating coils.
The temperatures are only examples and may vary between different installations and
time of year.

Contact with F2040
F2040 has an integrated control system that controls and monitors the
heat pump operation. At installation the installation engineer makes the
necessary settings of the control system on the indoor module, so that the
heat pump works optimally in your system.
The heat pump is controlled in different ways depending on your system.
If you have an indoor module, e.g. VVM 310 or VVM 320, you can control
heat pump operation from it. See relevant manual for more information.

Maintenance of F2040
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient oversight can cause serious damage to F2040 which is not
covered by the guarantee.
Checking grilles and bottom panel
Check that the inlet grille is not clogged by leaves, snow or anything else
regularly throughout the year.
You should be vigilant during windy conditions and/or in the event of
snow as the grilles can become blocked.
Also check that the drain holes in the bottom panel (three) are free from
dirt and leaves.
LEK
Prevent snow building up and covering the grille on F2040.
Chapter 2 | The heat pump – the heart of the house
NIBE™ F2040
15
LEK
Keep free of snow and/or ice.
Cleaning the outer casing
If necessary the outer casing can be cleaned using a damp cloth.
Care must be exercised so that the heat pump is not scratched when
cleaning. Avoid spraying water into the grilles or the sides so that water
penetrates into F2040. Prevent F2040 coming into contact with alkaline
cleaning agents.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has installed a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Saving tips
Your heat pump installation produces heat and cooling and/or hot water.
This occurs via the control settings you made.
Factors that affect the energy consumption are, for example, indoor temperature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
႑
16
Open the thermostat valves completely (except in the rooms that are
to be kept cooler for various reasons, e.g. bedrooms). The thermostats
slow the flow in the heating system, which the heat pump wants to
compensate with increased temperatures. It then works harder and
consumes more electrical energy.
Chapter 2 | The heat pump – the heart of the house

Chapter 2 | The heat pump – the heart of the house
NIBE™ F2040
New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
heating curve offset and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

Additional heat:
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for example, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
Ambient temperature sensor
A sensor that is located outdoors on or close to the heat pump. This sensor
tells the heat pump how hot it is where the sensor is located.
Balance temperature
The balance temperature is the outdoor temperature when the heat
pump’s stated output is equal to the building’s output requirement. This
means that the heat pump covers the whole building’s output requirement
down to this temperature.
Charge coil
A charge coil heats the domestic hot water (tap water) in the heater with
heating water from F2040.
Charge pump
See "Circulation pump".
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
Climate systems can also be called heating systems. The building is heated
using radiators, under floor coils or convector fans.
Coil tank
A heater with a coil in it. The water in the coil heats the water in the
heater.
Chapter 5 | Glossary
NIBE™ F2040
23
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
COP
If it is stated that a heat pump has COP 4, this means, in principle that if
you insert 10 pence, you will get 40 pence worth of heat. It is the efficiency
of the heat pump. This is measured at different measurement values, e.g.:
7/45 where 7 stands for the outdoor temperature and 45 for how many
degrees the supply temperature is.
Defrosting
A short process that periodically thaws ice on the evaporator using heat
from the heating medium. Large quantities of condensation water can
occur and must be routed away.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.
In most cases, the heat pump notes malfunctions and indicates this with
alarms in the display.
Domestic hot water
The water one showers in for example.
Double-jacketed tank
A heater with domestic hot water (tap water) is surrounded by an outer
vessel with boiler water (to the house radiators/elements). The heat pump
heats the boiler water, which in addition to going out to the all the house
radiators/elements, heats the domestic hot water in the inner vessel.
24
Chapter 5 | Glossary
NIBE™ F2040
Efficiency
A measurement of how effective the heat pump is. The higher the value
is the better it is.
Electrical addition
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature of the refrigerant drops.
Expansion vessel
Vessel with heating medium fluid with the task of equalising the pressure
in the heating medium system.
Flow pipe
The line in which the heated water is transported from the heat pump out
to the house heating system (radiators/heating coils).
Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water.
Chapter 5 | Glossary
NIBE™ F2040
25
Heating medium side
Pipes to the house’s climate system make up the heating medium side.
Hot water heater
Container where domestic water is heated. Is located somewhere outside
the heat pump.
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if nonpermitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with F2040.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and during condensing,
gives off heating energy.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water heater, when the heat pump
produces hot water.
