Heat pump general

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.

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.

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.

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.

Arguments for REMKO

■ Low heating costs in comparison

to oil and gas

■ Heat pumps represent a contribution

to environmental protection

■ Lower CO 2 emissions in comparison

to oil and gas heating

■ Numerous models are able to

cool as well as heat

■ Low noise level of the outdoor

unit

■ Flexible erection due to split

system design

■ Negligible maintenance costs

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

Functional diagram heating

inverter heat pump

Condensing

Outdoor area

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 floor-mounted units, condensation

pans, condensate trough

heating, 3-way switching valves,

overfl ow valves and additional

sensors are available as accessories.

Indoor area

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 alternative

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.

Layout

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 (tR-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 (tR-tA).

An approximate allowance for water

heating per person amounts to

0.2 kW according to VDI 2067.

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/m 2 =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.

Heating capacity in kW

Necessary additional

Bivalence point

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.

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:

■ Can be used everywhereAir is

available everywhere in unlimited

quantities. For example, no

wells are required.

■ No excavation work requiredNo

large areas are required for soil

collectors.

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).

■ EconomicalExpensive drilling is

not required.

■ Excellent value for money and

simple installation

■ Particularly suitable for lowenergy

houses with low inlet

temperatures

■ Ideal for bivalent operation, in

order to save energy

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.

1/3 The inverter requires 1/3 of the time of

conventional systems to start up

Time T

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.

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.

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.

Relative air humidity in %

Comfy

Still comfy

Uneasily humid

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.

Uneasily dry

Room air temperature in °C

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.

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.

Electrical connection

For the CMF and CMT devices, a

mains cable must be laid for both

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.

CAUTION

A clockwise rotating field must

be ensured for 400 V power

supplies.

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 fusing level is to be taken from

the technical data.

It is possible that the energy supply

company will provide a special

power supply tariff for the operation

of heat pumps.

Individual tariff options should be

agreed with the local energy supply

company.

CAUTION

Check all plugged and clamped

terminals to verify they are

seated correctly and making a

permanent contact. Re-tighten

as required.

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.

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

configuration of the heating

system and the components.

■ The leads are to be connected

in accordance with the terminal

assignment diagram.

CAUTION

Ensure correct polarity when

connecting the electrical leads.

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

The 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.

NOTE

In the event of insufficient cable

length, the sensor cables can

be extended up to a maximum

of 100 m with 1.5 m² diameter

wire.

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 fixed to a pipe.

■ The corresponding site must be

cleaned. Subsequently a thermal

compound (A) is applied

and the sensor is fixed in position.

External sensor

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.

22


Connection of refrigerant lines

■ The outdoor module and the

indoor module are connected

with two copper pipes of dimensions

“ and “.

CAUTION

All work must be excluded

which could cause soiling or

the infiltration of chips into the

refrigerant pipes!

CAUTION

The connection of refrigerant

pipes and the handling of

refrigerant may only be carried

out by authorised specialist

personnel.

■ 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 fitted

with additional pipe insulation

by the customer in order to

minimise performance loss.

■ The copper pipes are to be

flanged in order to make the

connections to the modules.In

doing so, check that the flange

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.

Oil pump bend

in suction pipe to

outdoor module1

every 2.5 metres of

rising pipe

Radius:

min 50 mm

Unit connector

Outdoor unit

up to 20 m

Indoor unit

■ 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

fit.

■ 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 rectified.

Pumping down to vacuum

■ The positive pressure must be

removed from the refrigerant

pipes.

■ The vacuum pump should have

an absolute final partial pressure

of 10 mbar in order to

remove all foreign gasses in the

pipelines.

Add refrigerant

■ The outdoor module contains a

sufficient 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 filling 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.

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.

41


REMKO CMF / CMT

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.
