F2040 – An excellent choice
F2040 is an air/water heat pump, specially designed for the Nordic climate,
which uses the outdoor air as its energy source.
The heat pump is intended for connection to water borne heating systems
and can both heat hot water effectively at high outdoor temperatures
and give a high output to the heating system at low outdoor temperatures.
If the outdoor temperature drops to a level below the stop temperature
all heating must then occur with external additional heat.
Excellent properties for F2040:
■Efficient twin rotary compressor
Efficient twin rotary compressor that operates at temperatures down
to -20 °C.
■Intelligent control
F2040 connected to intelligent control for optimum control of the heat
pump.
■Fan
F2040 has automatic capacity regulation of the fan.
■Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
The material has been chosen for a long service life.
■Many possibilities
F2040 is intended to be combined with NIBE indoor module VVM / NIBE
control module SMO. There is a wide range of system solutions and ac-
cessories for indoor modules and control modules.
■Silent operation
F2040 has a silent operation function that allows scheduling when F2040
must operate at an even quieter noise level.

9F2040Chapter 2 | The heat pump – the heart of the house

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 dis-
tributed around the house.
Outdoor air
The outdoor air is sucked into the heat pump.
A
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.
B
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.
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. 5 °C to
approx. 80 °C.
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 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).
G
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.
H
The temperatures are only examples and may vary between different installations and
time of year.
