Economical and environmen­tally-conscious heating

The burning of fossil-based energy
sources in order to generate power
creates severe consequences for the
environment. A high percentage of
fossil fuels is also problematic due
to the limited resources of oil and
gas and the price increases result­ing from this. For this reason, many
people today are thinking both
economically and environmentally­consciously in terms of heating.

The application of heat pump
technology enables both of these
concepts to be combined. It makes
use of the energy which is perma­nently available in the air, water
and soil and converts it into usable
heating energy by means of input­ting electrical energy.

Heat sources

There are essentially three heat
sources that heat pumps can derive
energy from. These are air, soil and
groundwater. The air heat pumps
have the advantage that the air
source is available everywhere are
in unlimited amounts an that it can
be utilised free-of-charge. A disad­vantage is that the outside air is at
its coldest when the heat require­ment is greatest. Brine heat pumps
extract energy from the soil.

However, in order to generate a
heat content of 4kW, it is only
necessary to input approximately
1kW of electricity. The rest is made
available free-of-charge by the
environment.

This is undertaken in serpentine
pipe networks which are laid ap­prox. 1m deep or placed by means
of drilling. The disadvantage is the
large space requirements for the
serpentine pipe networks or the
high cost of drilling. A permanent
cooling of the soil is also possible.

Water heat pumps require two
wells in order to obtain heat from
the groundwater, one supply well
and one dry well. The development
of this source is not possible every­where, it is expensive and requires
planning permission.

REMKO CMF / CMT

A heat pump is a device which
makes use of a working medium
to absorb ambient heat under low
temperatures and transports this
heat to a place where it can be
of use for heating purposes. Heat
pumps work according to the same
principles as a refrigerator. The dif­ference is that the "waste product"
of the refrigerator, the heat, is the
goal in this case.

The main components of the
refrigeration circuit consist of an
evaporator, compressor, liquefier
and expansion valve.
Finned evaporators serve to evapo­rate the refrigerant at low pressure
even at low heat source tem­peratures, thereby absorbing the
ambient energy. In the compres­sor, the refrigerant is compressed
to a higher pressure by means of
applying electrical energy, thereby
increasing it up the correct tem­perature level.Afterwards the hot
refrigerant gas reaches the liquefier,
a plate heat exchanger.
Here the hot gas condenses and
releases its heat to the heating
system.The liquefied refrigerant is

Heat pump modes

Heat pumps can work in various
operating modes.

Monovalent The heat pump is the
sole heating appliance in the build­ing all year round.This mode is par­ticularly suitable for heating plants
with low supply water temperatures
and is primarily used in combina­tion with brine/water and water/
water heat pumps.

Single energy sourceThe heating
system does not require a second­ary heating boiler. The heat pump
covers a large proportion of the re­quired heating power. Occasionally,
when it is extremely cold outside,
an electrical booster heating system
switches on in order to support the
heat pump as required.

Bivalent parallel modeThe heat
pump provides the entire heating
energy down to a predetermined
outdoor temperature. If the out­door temperature falls below this
value, a secondary heating appli­ance switches on in order to sup­port the heat pump.
This may take the form of alterna-
tive operation with oil or gas-fired
heating or regenerative operation
utilising solar energy or wood fuel
heating.
This mode is possible for all heating
systems.

then decompressed and cooled in a
flow regulator, the expansion valve.
Subsequently, the refrigerant flows
back into the evaporator and the
circuit is completed.

A heat pump manager is used in or­der to control the process, which in
addition to all safety functions also
provides fully automatic operation.
The water circuit for the CMF Series
indoor units includes a circulation
pump, a plate heat exchanger,
dirt trap, safety valve, manometer,
filling and drain valve, automatic
deaerator and flow monitor.The
CMT Series is additionally equipped
with a diaphragm expansion vessel,
a three-way switching valve and a
storage tank.

Wall and fl oor-mounted units, con­densation pans, condensate trough
heating, 3-way switching valves,
overfl ow valves and additional
sensors are available as accessories.

The diagram with the heating ca­pacity characteristics shows a sim­plified linear heating requirement.
A connecting line is drawn from the
desired room temperature (20°C)
and the point where the average
low outdoor temperature (local low
for the year) and the heat require­ment meets (in this case: -14°C and

7.4kW). The intersection of the two
curves are plotted on the X axis
and the temperature of the balance
point is read off. In this case it is

-5°C.

The size of the submersion tube
heater is the difference between
the maximum heat requirement on
the coldest days of the year and the
heating output on these days. In
the example, the required output is

7.4kW – 4.7kW = 2.7kW.

A residential home comprised of
160m² living-space and a heat
requirement of 40 W/m² has been
selected for the example design.
A total of five persons live in the
house. The heating load amounts
to 160m

2

40W/m2=6,400W. Add­ing a drinking water allowance of
1 kW results in a required heating
power of 7.4kW.

The dimensioning of the heat pump
is given graphically on the diagram
below together with the outdoor­temperature-dependent building heat
requirements and the heating capacity
characteristics for the heat pump.

A precise calculation of the build­ing's heating load according to EN
12831 is required for the design
and dimensioning of a heating
system.
However, approximate require­ments can be determined based
on the year of construction and
the type of building. The adjacent
table shows the approximate spe­cific heating loads for a number of
building types. The required heat­ing system output can be calcu­lated by multiplying the area to be
heated with the given values.

Various factors have to be consid­ered in order to achieve a precise
calculation.The transmission heat
requirement, the infiltration heat
loss and an allowance for water
heating comprise the total heating
output which has to be provided by
the heating system.

The total area of the floor surfaces,
exterior wall windows, doors and
roofing is required in order to
determine the transmission heat
requirement. In addition, informa­tion about the materials used in the
building is required, as these lead
to extremely varied thermal trans­mission coefficients (the so called
K value). Also required is the room
temperature and the average low,
the lowest average outdoor tem­perature of the year.
The formula for determining the
transmission heat requirement
isQ=A U (t

R-TA) and this must be

calculated individually for the areas
surrounding all rooms.

The infiltration heat requirement
takes into consideration how often
the heated room air is exchanged
for cold external air. The room vol­ume V, the air exchange frequency
n and the specific heat capacity of
the air is also required in addition to
the room temperature and average

low temperature. The formula for
this is Q=V n c (t

R-tA).

An approximate allowance for wa­ter heating per person amounts to

0.2 kW according to VDI 2067.

Characteristics of REMKO inverter heat pumps

Heat source outdoor air

An air/water heat pump absorbs
energy from the outdoor air as its
heat source and transmits this to
the heating system.They have the
following advantages over a brine/
water and water/water heat pump
system:

Split AC unit

The REMKO

inverter heat pump is
a so called split AC unit. This means
that is consists of an outdoor unit
and an indoor unit, both of which
are connected via refrigerant-carry­ing copper pipes. This means that
there are no water-carrying pipes
laid from the indoors to outdoors
which need to be made frost proof.
The outdoor unit contains only the
condenser, the evaporator and the
expansion valve. This means that
the outdoor unit is considerably
smaller.
The indoor module contains the
liquefier for the circuit and the con­nections for the heating network.

The heat pump's condenser is
equipped with a requirement-de­pendent speed control system. The
power control on conventional heat
pumps provides only two states,
either on (full power) or off (no
power). The heat pump switches
on when the temperature drops
below a certain level and switches
off again when this temperature
has been reached.
This type of power control is
extremely inefficient.The power
control on REMKO'S

inverter heat
pumps is continuously modified to
the actual heat requirement.

The electronics system has an
integrated frequency converter
which serves to modify the con­denser speed and the speed of the
evaporator fan as required. The
condenser works at a higher speed
when under full load as when it
is under partial load. The lower
speeds ensure a longer operational
lifetime for the components, im­proved coefficient of performance
and lower noise.
Lower speeds also result in lower
energy consumption (electricity).

Defrost by circulation reversal

At temperatures under approx. 5°C
atmospheric moisture freezes on
the evaporator which can lead to
the formation of an ice layer. This
can cause the heat transfer from
the air to the refrigerant and the air
flow to be reduced.
In this case, the ice must be removed.
A four-way valve serves to reverse
the refrigerant circuit, so that the
hot gas from the compressor flows
through the original evaporator and
the ice that has formed there can
melt.
The defrost process is not initiated
after a predetermined time, rather it
is carried out as required in order to
save energy.

Cooling mode with models
CMF 90, CMF 150, CMT 100
and CMT 150

Due to the circulation reversal sys­tem, a number of REMKO inverter
heat pump models also offer cool­ing operation.
Cooling mode utilises the refriger­ant components in order to produce
cold water, in order that heat can
be removed from the building.
This can either take the form of
dynamic cooling or passive cooling.

Under dynamic cooling the re­frigerating capacity is actively
transferred to the indoor air. This
is undertaken by means of water­based fan convectors. In doing so,
it is desirable that the inlet temper­atures are under the dewpoint, in
order to transfer a higher refrigerat­ing capacity and to dehumidify the
indoor air.

Passive cooling refers to the ab­sorption of heat via cooled floors,
walls or ceiling surfaces. In doing
so, water-carrying pipes make the
structural sections into thermi­cally effective heat exchangers. In
order to achieve this, the refriger­ant temperature has to lie above
the dewpoint, in order to avoid the
formation of condensation. Dew­point monitoring is required for this
purpose.

We recommend dynamic cooling
with fan convectors, in order to
achieve increased thermal perform­ance and in order to dehumidify the
air on muggy summer days. The
advantage here is that dewpoint
monitoring is not required.

Versions

We offer two different indoor unit
designs.
The wall-mounted CMF Series is
equipped with a circulation pump
and a safety module on the up­stream face. In addition, an electri­cal heating coil can be integrated.
The CMT Series of indoor modules
is additionally equipped with a stor­age tank and an expansion vessel.
The storage tank has a capacity of
150 litres.
We recommend an external storage
tank for the CMF Series in order to
avoid short operating times for the
heat pump and in order to ensure
that sufficient energy is available to
bridge off-periods.

The comfort zone shows which values for temperature and humidity
are considered comfortable for people. This range should ideally be met
when heating or air-conditioning buildings.

the outdoor and indoor modules.
In some cases it may also be pos­sible to feed the power supply
for the indoor module from the
outdoor module. The outdoor
modules of Series CMF 80, CMF
90, CMT 100 require a 230V
mains supply. The outdoor mod­ules of Series CMF 140, CMF 150
and CMT 150 have to be provided
with a 400 V supply. The electrical
connection between the modules
is realised with a 4-wire control
cable.

A clockwise rotating field must
be ensured for 400 V power
supplies.

CAUTION

The following diagram provides an
overview of the required connec­tions.
The diameters for the leads and
the connection cables are to be
selected according to local regula­tions.

The side wall of the the unit
is to be removed by means of
loosening the screws in order to
connect the mains supply (see
"Installation of the Outdoor
Module").

■

Details concerning the electri­cal protection of the system are
given in the technical data.

The required diameters are to

be observed!

■

The supply cable must be con­nected under consideration of
the correct polarity.

■

The electrical connection dia­gram is to be observed.

■

The four-wire control cable is to
be connected to terminals S1,
S2, S3 and the earth terminal.

■

The correct polarity must be
ensured when connecting the
connection cables.

■

If the outdoor module is in­stalled on a roof, then it must
be protected against lightening
strikes.

■

The cables are to be secured
with the cord grips.

Electrical connection of the indoor
module

The following points refer to the
fi gures shown below. The CMF
Series indoor module is shown in
the example. The connection for
the CMT Series is established cor­respondingly.

1. The lower housing cover is
folded down and removed.

2. The front of the housing is fi xed
in position with two screws and
can be taken out in an upward
direction after the screws are
released.

3. The cover of the switching cabi­net can be folded down and
removed after the two screws
have been removed.

4. After the screws have been
released, the switching cabinet
can be folded down in order to
facilitate installation.

Ensure correct polarity when
connecting the electrical leads.

CAUTION

5. The cable passages serve to en­able the supply lines to be fed
in for the indoor unit as well as
the connection cable between
the indoor and outdoor mod­ules and the leads for the exter­nal devices and sensors into the
indoor module.

In doing so, it is to be ensured

that the cable passages for the
CMT Series are at the top.

■

The number of lines and the
sensors is dependent on the
confi guration of the heating
system and the components.

■

The leads are to be connected
in accordance with the terminal
assignment diagram.

If an electricity tariff has been selected without energy
supply company shut-off, then a bridge is to be cre­ated between terminals X1.5 and X1.6.

If an electricity tariff with energy supply company
shut-off is selected, then the customer is to arrange
for an on-site starter contact for terminals X1.5 and
X1.6. Likewise, the supply line for the outdoor mod­ule requires an interruption mechanism installed by
the customer in accordance with the energy supply
company's off-periods. In this case it is necessary to
have a separate supply line for the indoor unit! The
booster heating system requires a separate supply line
with fuse protection in the switching cabinet con­nected to contactor terminal K1.

REMKO CMF / CMT

Temperature sensors

External sensorThe number of sensors required

can vary with the type of system.

The indoor module contains the
collector sensor, the return sensor
and the sensor for the liquid line.
The scope of delivery contains the
external sensor and immersion
sensor.

When connecting a solar collector,
the PT-1000 sensor has to be used
for measuring the collector tem­perature! All other sensors have to
be NTC-sensors with a reference
resistance of 5 kilo Ohms.

All sensors are to be connected
to the indoor module switching
cabinet in accordance with the
terminal assignment diagram.

The connection of an outdoor sen­sor is always required for the heat
pump manager.

■

The outdoor sensor is to be
mounted in a north-easterly
direction approx. 2.5 metres
above the ground. It may not
be subjected to direct sunlight
and is to be protected against
excessive wind. Installation
above windows or air ducts is
to be avoided.

■

In order to carry out installa­tion, the cover is to be removed
and the sensor is to be fastened
with the screws included.

■

A cable with wire diameters of

1.0 mm² is recommended for
connecting the sensor.

Contact sensor

Contact sensors can be mounted
on the pipes in order to measure
e.g. the heating circuit tempera­tures.

■

The contact sensors are fi xed
in position with the enclosed
trapezoidal brackets and the
retaining strap is fi xed to a pipe.

■

The corresponding site must be
cleaned. Subsequently a ther­mal compound (A) is applied
and the sensor is fi xed in posi­tion.

In the event of insuffi cient cable
length, the sensor cables can
be extended up to a maximum
of 100 m with 1.5 m² diameter
wire.

NOTE

22

■

The outdoor module and the
indoor module are connected
with two copper pipes of di­mensions “ and “.

All work must be excluded
which could cause soiling or
the infiltration of chips into the
refrigerant pipes!

CAUTION

Indoor unit

The connection of refriger­ant pipes and the handling of
refrigerant may only be carried
out by authorised specialist
personnel.

CAUTION

Connection of refrigerant lines

■

Only suitable tools may be
used.

■

Observe the permitted bending
radius for the refrigerant pipes
during installation in order to
prevent kinks. Never bend a
pipe twice in the same place in
order to prevent embrittlement
or crack formation.

■

Suitable fastening and insula­tion is to be ensured when
laying the refrigerant pipes.

■

The outdoor sections of the
refrigerant pipes should be fi t­ted with additional pipe insula­tion by the customer in order to
minimise performance loss.

■

The copper pipes are to be
fl anged in order to make the
connections to the modules.In
doing so, check that the fl ange
has the correct shape and suit­able union nuts.

■

If the outdoor unit is installed
at a higher level than the
indoor unit, suitable oil return
measures must be taken. This
is generally achieved by an oil
pump bend installed for every

2.5 metres of height difference.

Unit connector

■

The enclosure panel is to be
removed from the outdoor
module. It may be necessary to
remove the pre-cut bushings.

■

The connection of the refriger­ant pipes to the device connec­tions are to initially be made by
hand, in order to ensure a good
fi t.

■

Subsequently the threaded
assemblies are to be fastened
with two adjustable spanners.
One of the spanners is to be
used to counter the rotation.

■

The installed refrigerant pipes
including the connectors must
be provided with suitable ther­mal insulation.

Tightness check

■

Connect the manometer station
to at least one Schrader valve
on the stop valves of the out­door module.

■

The tightness test is to be un­dertaken with dried nitrogen at
a test pressure of 40 bar.

■

The connections and connec­tors of the pipelines must be
checked with a suitable leak
detector and any leaking areas
are to be rectifi ed.

Pumping down to vacuum

■

The positive pressure must be
removed from the refrigerant
pipes.

■

The vacuum pump should have
an absolute fi nal partial pres­sure of 10 mbar in order to
remove all foreign gasses in the
pipelines.

Add refrigerant

■

The outdoor module contains a
suffi cient refrigerant fi lling for a
pipe length of up to 30 metres.

■

If the length of any of the pipe­lines exceeds 30 metres, then
an additional fi lling of 60g per
additional metre of pipe length
(single length) is required.

Before start up

■

The stop valves are to be fully
opened in an anticlockwise di­rection with a hexagon wrench.

Care and maintenance

Regular care and maintenance
ensuretrouble-free operation and a
long service life.

Care

■

The indoor and outdoor mod­ules must be kept free of
soiling, vegetation and other
deposits.

■

The device is to be cleaned with
a damp cloth. In doing so, it
is to be ensured that no caus­tic, abrasive or solvent-based
cleaning products are used. Use
of powerful water jets is to be
avoided.

■

The fi ns on the outdoor module
are to be cleaned after long
standstill periods.

Prior to performing any work,
ensure the equipment is iso­lated from the voltage supply
and secured to prevent acci­dental switch-on!

CAUTION

Maintenance

■

It is necessary to arrange a
maintenance contract on an
annual basis with a respective
specialist fi rm.

As the refrigerant fi ll quantity
exceeds 3kg, an

annual

tight­ness check has to be carried
out on the refrigerant circuit
by a specialist fi rm.

NOTE

Temporary decommis­sioning

The system may not be switched
off at the mains power supply even
if the heating system is not used for
heating purposes over an extended

period (e.g. holidays)!

■

The system is to be switched to
"Stand-by" mode during tem­porary shut-down periods.

■

Heating phases can be pro­grammed for the duration of the
period of absence.

■

The previous operating mode
has to be switched back on
when the shut-down phase is
over.

■

Instructions on how to change
the mode is described in the
corresponding chapter of the
configuration manual.

Disposal of packaging

All products are packed for trans­port in environmentally friendly
materials. Make a valuable con­tribution to reducing waste and
sustaining raw materials. Only
dispose of packaging at approved
collection points.

In order to make warranty claims, it
is essential that the ordering party
or their representative complete
and return the "certificate of war­ranty" and commissioning report
to REMKO GmbH & Co. KG at the
time when the equipment is pur­chased and commissioned.
The warranty conditions are listed
in the "General business and deliv­ery conditions. The contractual par­ties can also agree additional terms
beyond the scope of the above. In
this case,first contact the contrac­tual partner.

Environmental
protection and
recycling

Warranty

In "Standby" mode, the heat
pump is "switched off".
However, the frost protection
function of the entire plant
remains active.

NOTE

Disposal of units and compo­nents

For the manufacture of the units
and components, only recyclable
materials have been used.
Help protect the environment by
ensuring that the units or compo­nents (for example batteries) are
not disposed in household waste,
but only in accordance with local
regulations and in an environmen­tally safe manner, e.g. through
authorised disposal and recycling
specialists or at collection points.

General

In the event of system malfunc­tions, fi rst check the control system
cabling and components for cor­rectness.

Sensors

All of the sensors can be checked

from the "General/ Service/Sensor
test" screen. All of the connected
sensors have to appear here with
plausible measured values.

Actuators (mixers, pumps)

All of the actuators can be checked
from the "General/ Service/relay
test" screen. This screen enables all
of the relays to be checked indi­vidually. This enables the correct
connection of these components
to be easily checked (e.g. mixer
direction of rotation).

Communication

The bus and sensor cables should
be checked in the event of com­munication faults. The cables are
to be spatially separated from
power lines. The polarity is also to
be checked.

Troubleshooting

A corresponding error code ap­pears on the heat pump manager
display in the event of a fault on
the heating system. The meaning
of the displayed error codes can be

taken from the following table.
The system should be restarted
after a brief shut-down after the
fault has been rectifi ed (mains
switch). Subsequently the heat

General terms

Defrosting

At outdoor temperatures below
5°C it is possible that ice may form
on the evaporators of air/water
heat pumps. The removal of this
ice is referred to as defrosting and
is undertaken by supplying heat,
either regularly or as requirements
dictate. Air/water heat pumps with
circuit reversal are distinguished by
their requirements-based, quick and
energy-efficient defrosting system.

Bivalent mode

The heat pump provides the entire
heating energy down to a pre­determined outdoor temperature
(e.g. 0°C). If the temperature drops
below this value, the heat pump
switches off and the secondary
heating appliance takes over the
heating, e.g. a heating boiler.

Sealing test

System operators are obliged to
ensure the prevention of refriger­ant leakage in accordance with the
directive on substances that deplete
the ozone layer (EC 2037/2000)
and the Regulation on Certain
Fluorinated Greenhouse Gases (EC
842/2006). In addition, a minimum
of one annual service and inspec­tion must be carried out, as well as
a sealing test for refrigerating plants
with a refrigerant filling weight over
3 kg.

Energy supply company
switching

Certain energy supply companies
offer special tariffs for the operation
of heat pumps.

Expansion valve

Heat pump component for lower­ing the condensing pressure on

the vapour tension. In addition,
the expansion valve regulates the
quantity of injected refrigerant in
relation to the evaporator load.

Sponsorship

The German Reconstruction Loan
Corporation supports ecologically
sound construction and modernisa­tion of domestic buildings for pri­vate individuals. This includes heat
pumps which can be supported
in the form of loans. The German
Federal Office of Economics and
Export Control (BAFA) subsidises
the installation of effective heat
pumps (please refer to: www.kfw.
de und www.bafa.de).

Limit temperature / balance
point

Outdoor temperature where the
secondary heating appliance cuts in
under bivalent operation.

Heating output

Flow of heat emitted from the
liquefier to the environment. The
heating output is the sum of the
electrical power consumed by the
condenser and the heat flux ob­tained from the environment.

Inverter

Power regulator which serves to
match the speed of the compressor
motor and the speed of the evapo­rator fans to the heating require­ment.

Seasonal performance factor

The seasonal performance factor
relates to the ratio of heat content
delivered by the heat pump system
to the supplied electrical energy in

one year. This is not the same as
the coefficient of performance.The
seasonal performance factor cor­responds to the reciprocal value of
the annual power input factor.

Annual power input factor

The annual power input factor
indicates the power input (e.g.
electrical energy) required in order
to achieve a certain benefit (e.g.
heating energy). The annual power
input factor includes the energy
required for auxiliary drives. Cal­culation of the annual power input
factor is undertaken according to
VDI – Directive 4650.

Refrigerating capacity

Heat flux extracted from the en­vironment by the evaporator (air,
water or soil).

Refrigerant

The working medium used in a
refrigerant plant, e.g. heat pump,
is referred to as the refrigerant.
The refrigerant is a liquid which
is used for thermal transfer in a
refrigeration plant and which is
able to absorb heat by changing
its state at low temperatures and
low pressures. A further change of
state at higher temperatures and
higher pressure serves to dissipate
this heat.

Compressor (condenser)

Unit designed for the mechanical
conveyance and compression of
gasses. Compression serves to sig­nificantly increase the pressure and
temperature of the medium.

Coefficient of performance

The current ratio of thermal out­put produced by the heat pump
to the consumed electrical power
is referred to as the coefficient of
performance, as measured under
standardised boundary conditions
according to EN 255 / EN 14511.
A coefficient of performance of 4
means that a usable thermal output
amounting to 4-times the electrical
power consumption is available.

Single energy source mode

The heat pump covers a large
proportion of the required heating
power. On a few days per year an
electrical heating coil supplements
the heat pump under extremely low
outdoor temperatures. Dimension­ing of the heat pump for air/water
heat pumps is generally based on
a limit temperature (also known as
balance point) of approx. -5 °C.

Monovalent mode

In this mode, the heat pump is
the sole heating appliance in the
building all year round. Monovalent
mode is primarily used in combina­tion with brine/water and water/
water heat pumps.

Storage tank

The installation of a hot-water stor­age tank is generally recommended
in order to extend the running time
of the heat pump under low heat
requirements. A storage tank is
required for air/water heat pumps
in order to bridge off-periods.

Noise

Noise is transmitted in media such
as air or water. Essentially there are
two types of noise, airborne sound
and solid-borne sound. Airborne
sound is transmitted entirely via the
air. Solid-borne sound is transmit­ted in solid materials or liquids and
is only partially radiated as airborne
sound. The audible range of sound
lies between 20 and 20,000 Hz.

Sound pressure level

The sound pressure level is a
comparable characteristic quantity
for the radiated acoustic output
of a machine, for example, a heat
pump. The noise emission level
at certain distances and acoustic
environments can be measured.
The standard is based on a sound
pressure level given as a nominal
noise level.

Split AC unit

Design where one part of the de­vice is positioned outdoors and the
other inside the building. Both units
are connected to each other by a
refrigerant pipe.

Evaporator

Heat exchanger on a refrigerant
plant which uses the evaporation of
a working medium in order to ex­tract heat from its environment at
low temperatures (e.g. the outdoor
air).

Liquefier

Heat exchanger on a refrigerant
plant which liquefies a working
medium in order to transmit heat
to its environment (e.g. the heating
system).

Regulations and guidelines

The erection, installation and com­missioning of heat pumps has to
be undertaken by qualified special­ist engineers. In doing so, various
standards and directives are to be
observed.

Heat requirement assessment

A precise dimensioning of the
system must be carried out for heat
pump systems in order to maximise
efficiency. Calculation of the heat
requirement is undertaken accord­ing to national standards. However,
approximate requirements can be
determined based on the W/m²
tables multiplied by living space to
be heated. The result of this is the
overall heat requirement, which
includes the transmission heat re­quirement and the infiltration heat
loss.

Heat pump system

A heat pump system consists of
a heat pump and a heat source
system. For brine and water/water
heat pumps, the heat source system
must be made available separately.

Heat source

Medium from which the heat pump
derives heat, in other words, soil,
air and water.

Heat carrier

Liquid or gas medium (e.g. water,
brine or air), in which heat is trans­ported.
