System description

In cooling mode, the unit (an air
to water chiller) takes heat out
of the operating medium to be
cooled, water or a mixture of
water and glycol, within a closed
medium circuit in the evaporator
(plate heat exchanger) and gives
it off to the closed cooling circuit.
As a consequence of the heat
exchange, the medium cools and
the refrigerant in the cooling circuit
vaporises under low pressure.
The gaseous refrigerant
enters an electric compressor
(scroll construction) which
increases the pressure and the
temperature of the refrigerant.
The gaseous refrigerant is
led into a finned condenser,
which, as a consequence of the
heat exchange, condenses the
refrigerant under high pressure to
a liquid. The air emerging at the
condenser heats the environment.
The liquid refrigerant is led by

7

means of a variable injector valve
back to the evaporator where the
circuit begins again.
In heating mode, an air-cooled
chiller with heat pump functions
(HP-function) can take up heat
from the ambient air in the finned
condenser and give it off to the
operating medium. A reversing
valve switches the cooling circuit
function.
A return temperature dependent,
adaptive control, which ensures
the unit's operation and all of the
safety functions, is used to control
the cooling or heating. A potential­free contact provides for remote
enabling.
The unit is designed for outdoor
installation. Under certain circum­stances, it can also be used indoors.
The unit cooling circuit comprises
an evaporator, compressor, thermal
injection valve, condenser, con­denser fan, fan control system and

high and low pressure controllers
Units with heat pump function also
have a reversing valve and a col­lecting flask.
The medium circuit comprises
a circulation pump, expansion
vessel, safety valve and differential
pressure switch. A storage tank is
not mandatory.

Winter pressure controls, cabled
remote control, crank case heat­ing, vibration dampers, heaters
for anti-freeze protection, external
medium storage tanks, glycol con­centrate and a technical handover
are available as accessories.

Operation

The system can be easily operated
via the fully automatic iChiLL
controller. If due to local conditions
programming via the internal
control can only be realised with
difficulty, the system can also be
controlled via a cabled remote
control (accessory) or an external,

v

Methods of operation

potential-free, enabling contact
(standard).

A centralised fault contact, part of
the standard equipment, can be
used for the external signalling of
a fault.

The unit is designed as a 2 conduc­tor system.
The system has 2 medium pipes
(conductors: supply and return)
for cooling using a cold medium
(KWL) or heating using a warm
medium (units with HP function
KWL...H).

In combination with a correspond­ing system, the output can be
transmitted to the room to be
cooled via the floor, the building
structure or by means of ceiling
cooling.
For each of the different systems,
a minimum flow volume and
a minimum medium volume must
be ensured for the plant.

NOTE

The escape of refrigerant con­tributes to climatic change. In
the event of escape, refrigerant
with a low greenhouse poten­tial has a lesser impact on glo­bal warming than those with a
high greenhouse potential.
This device contains refrige­rant with a greenhouse poten­tial of 1975. That means the
escape of 1 kg of this refrige­rant has an effect on global
warming that is 1975 times
greater than 1 kg CO2, based
on 100 years. Do not conduct
any work on the refrigerant
circuit or dismantle the de­vice - always enlist the help of
qualified experts.

! CAUTION

If the letter "A" is shown in
the display with a two-digit
numeric code, there is a fault
in the chiller. (see chapter on
trouble-shooting and customer
service).

Adaptive cooling and heating function

If the programmed target temperature within the system is reached quickly or only a small share of cooling or
heating capacity is accepted by the internal equipment, the operating time of the compressor decreases. An op­erating time which is too short can have a negative long-term impact on the operation of the unit. The control­ler continuously calculates the "Adaptive target value SEtr", so that a minimum operating time and minimum
stand-by time of the compressor of 3 minutes can be assured. In the process, the switch-on and shut-off point
of the compressor changes (hysteresis). The unit remains at this operating point until the cooling or heating
capacity accepted in the internal equipment has changed.

The adjustment of the target value has the consequence that the medium temperature can fluctuate beyond
the normal measure depending on the acceptance of the cooling or heating capacity within the system. If this
fluctuation should be decreased, the medium volume should be increased above the minimum medium volume,
e.g. through an additional storage tank.

If the temperature at the medium intake exceeds the target
value, the compressor switches on (A) and cooling capacity
is generated. If the calculated operating time of the com­pressor falls below 3 minutes, an adjustment of the target
value is made. If the calculated operating time is longer
than 3 minutes, the current target value is kept. The me­dium temperature lowers and the compressor is switched
off when the shut-off point is reached (B).

If the temperature at the medium intake exceeds the
target value, the compressor switches on (A) and heating
capacity is generated. If the calculated operating time of
the compressor falls below 3 minutes, an adjustment of
the target value is made. If the calculated operating time
is longer than 3 minutes, the current target value is kept.
The medium temperature increases and the compressor is
switched off when the shut-off point is reached (B).

Programming target values

The input of the target values for summer mode (cooling mode) and the transition mode (heating mode only
for units with HP function) takes place on the user level. The following diagrams provide simplified illustrations

Installation instructions for qualified personnel

■

Important information
before installing

■

Observe the manuals for the
cold water user (indoor units)
and chiller or heating system
when installing the entire
system.

■

The interior units user and the
chiller work independently. A
connection between the two is
not necessary.

■

Transport the unit in its original
packaging as close as possible
to the installation location.
This avoids transportation
damage.

■

The units may only be moved
as installed (upright) using
appropriate transport gear
(Figure 1).
Secure against tipping!

■

The unit must be kept upright
when transporting to a higher
elevation (Figure 2).

■

Check that the packaged
contents are complete and
inspect the unit for any visible
signs of transportation damage.
Report any damage
immediately to your contracting
party and the shipping
company.

Lift the unit only at intended
lifting points. Never stress the
medium or refrigerant piping.

■

The medium connection lines,
valves and connections must
be insulated against vapour
diffusion. If necessary, also
insulate the condensate line
(only units with HP-function).
In dual systems with cooling
and heating modes, the
requirements of the current
Energy-Savings-Ordinance
(EnEV) are to be complied with.

■

Seal off open lines against dirt
and never kink or crimp the
lines.

■

Avoid unnecessary bending.

■

Establish all electrical
connections connections in
accordance with the relevant
DIN- and VDE standards.

■

Always fasten electric wiring
properly to the terminals,
otherwise there is a risk of fire.

■

Comply with all regulations
governing structural and
building requirements and
conditions with regard to the
installation site.

■

In the selection of the
installation site, pay attention
to the site itself and to any
possible acoustic reflection from
surrounding units.

■

To avoid the transmission of
vibrations to the installation
site, the units must be installed
on vibration absorbing material
or on vibration decoupled
foundations.
In doing so, make sure that
the lines are also vibration
decoupled.

■

If the installation site must
fulfil special sound emission
requirements, these must
be realised on-site when
appropriate adjustments can be
made.
In these cases, please consult an
appropriate acoustics expert.

2 Correct way to lift

Lifting point

■

Select an installation location
which allows air to freely
flow through the intake and
outlet. See section "Minimum
clearances".

■

Do not install the unit in the
immediate vicinity of devices
with intensive thermal radiation.
Installation near thermal radiation
reduces the unit output.

18

1 Correct way to move

Wall openings

■

We recommend that the inside
of the opening be padded or
lined for example with a PVC
pipe to prevent damage to the
lines.

■

After installation, the wall
opening should be closed off
with a suitable sealant. Do not
use materials containing cement
or lime!

Installation material

The unit is fastened on vibration
dampers (accessories) to the floor
by means of bolts. The carrying
capacity of the console and the
wall must be taken into account
when fastening to the wall.

Selection of the installation
location

The unit is designed for horizontal
installation on a base in outdoor
areas. The installation site must
be level, flat and firm. The unit
should also be secured to prevent
toppling.

The unit can be installed outside as
well as inside a building.

In the case of outdoor installation,
please follow the instructions given
below to protect the unit against
the weather.

Exposure to sunlight further
increases the temperature of the
fins and reduces the heat released
by the finned heat exchanger.

The unit should, whenever
possible, be installed on the north
side of the building.

If necessary, take measures
to provide sufficient shade
(responsibility of customer).

This can be accomplished with
a small roof covering.

However, the discharging warm air
flow may not be affected by the
measures.

Wind

If the unit is being installed where
it is windy, care must be taken that
the discharged warm air is carried
off in the prevailing wind direction.
If this is not possible, it may be
necessary to install a windbreak
on-site (Figure 3).

Ensure that the windbreak does
not adversely affect the air intake
to the unit.

Snow

The unit should be wall-mounted
in areas of heavy snowfall.

Installation should then be at
least 20 cm above the expected
level of snow to prevent snow
from getting into the outdoor unit

(Figure 4).

Installation inside buildings

■

Ensure that heat can dissipate
adequately when placing the
outdoor unit in cellars, attics,
adjoining rooms or halls (figure 5).

■

Install an additional fan with
the same air flow as that
of the outdoor unit being
installed in the room which
can compensate any additional
pressure losses with ventilation
ducts (Figure 5, Page 20).

■

Ensure a continuous and
unobstructed air flow from
outside, preferably using
sufficiently large air openings
(Figure 5, Page 20).

NOTE

Cooling or heating perform­ance changes as a conse­quence of the ambient condi­tions influenced by rain, sun,
wind, and snow.

Rain

The unit should be at least 10 cm
off the ground when mounted on
the roof or ground. when mounted
on the roof or ground.

For cooling and heating units (only
HP-function) elevated installation
increases the generated heat
capacity.

Connection of the
medium piping

■

The connection of the lines
on-site takes place on the front
side of the unit.

■

For the purpose of servicing,
connections must be equipped
with shut-off valves and flow
volumes adjusted using pipe leg
regulating valves.

■

Additional automatic bleed
valves are to be provided in the
supply and return at the instal­lation's highest point.

■

The medium piping may not
exert any structural load on the
unit.

■

The line connections may not
generate any thermal or me­chanical stresses on the unit.
If necessary cool line or support
with the second tool.

■

If the unit is at first to be oper­ated with only a part of the
entire system, the medium flow

a pipe leg regulating valve.

■

The pipe sizing is to be de­signed so that the required

Minimum/maximum medium flow

The chiller`s circulation pump gen­erates a constant medium flow;
the result is a loss of pressure in
the system and in the chiller. The
differential pressure switch in the
chiller measures the medium pres­sure loss over the evaporator and
switches the unit off if the mini­mum flow volume is undercut.
The medium flow limit may like­wise not be exceeded (maximum
flow volume).
A 3-way valve with bypass and
a hydraulic switch to establish a
primary and secondary circuit or
a volume dependent bypass are
necessary to ensure a constant
flow volume.

Minimum medium volume, of the
system

As a consequence of the adaptive
controller a storage tank is not
mandatory. However, the mini­mum medium volume may not be
fallen short of in order to ensure
fault-free operation of the unit.

NOTE

To regulate the circulation pump
we recommend a main
pipe regulating valve near the unit.

! CAUTION

Medium piping

Medium piping can be made of
copper, steel or plastic. To minimise
pressure losses, only streamlined
fittings should be used.
When designing the layout, the
large flow volumes in cold wa­ter systems, high pressure losses
in connection with water-glycol
mixtures and the chiller's minimum
flow volume must be taken into
account.
The lines are to be insulated
against vapour diffusion and,
if necessary, the current Energy­Savings-Ordinance (EnEV) must to
be observed. UV resistance must
be realised outdoors.

Pressure gauge and thermometer

The pressure gauge and thermom­eter to be installed on-site at
the intake and outlet serve to set
the medium flow. The display
should mean shut down In the
system there are temperature
sensors in the medium intake and
medium outlet.
The temperature at the probes can
be seen on the controller.

Valves for hydronic balancing

Through valves for hydronic bal­ancing to be installed on-site,

individual pressure losses of each
individual unit in the pipeline
network design must be adjusted
to the entire system. The nomi­nal flow volumes for the medium
adjust to the necessary values as
a consequence of the pressure loss.

Frost protection (accessories)

As a medium for a cold water
system, a water-glycol mixture
is used as a rule. Depending on
the use to which the glycol type
and quantity is put, the viscos­ity changes, the loss in pressure
increases and the unit's cooling or
heating capacity reduces. All sys­tem components must be ap­proved for use with glycol.
As a rule, the addition to the water
of ethylene glycol, in a proportion
of 34%, with inhibitors for corro­sion protection is recommended.
This concentration ensures anti­freeze protection to –20°C; at lower
temperatures, an ice porridge forms
which has no explosive effect.
The toxicologically harmless
propylene glycol should be used if
there is a risk that the medium can
come into contact with drinking
water or food stuffs. To inhibit the
explosive effects, a proportion of
38% is necessary as a rule.

During use and
disposal the product and safety
data sheets of the glycol type
which is used must be ob­served.

! CAUTION

Use the required type and
mixture to ensure the freezing
point.

Diaphragm expansion vessel (MAG)

To avoid pressure fluctuations
during standstill because of
temperature changes, diaphragm
expansion vessels filled with
nitrogen (moisture neutral) must
be integrated in the system.

The unit's standard equipment
includes one diaphragm expansion
vessel. The preliminary pressure
must be set on the system; an
increase in volume or, in the event
of the realisation of a cooling­heating system, the installation
of another diaphragm expansion
vessel may be necessary.

Compensators

Compensators are used to connect
lines to the unit to prevent vibra­tion in the chiller from transmitting
to other parts of the system.

Safety valve

Safety valves limit excess operat­ing pressure due to excess warm­ing or overfilling of the operating
medium. The valve outlet requires
unobstructed draining into a drain
line. Applicable local disposal ordi­nances must be observed if glycol
is used.
The unit's standard equipment
includes one safety valve.

Shut-off valves

As a rule, in cold water systems,
shut-off valves with full admission
should be used. For the purpose
of servicing, medium intake and
medium outlet must be equipped
with shut-off valves (if necessary
safety valves).

Air bleeding valves

The unit has manual air bleeding
valves. The unit can be vented
separately after the system
has been filled. Automatic air
bleeder must also be installed at
the highest point in the collective
lines.

less than 10 mesh/cm². Shutoff
valves should be installed on both
sides of the dirt trap.

! CAUTION

Improperly installed or missing
dirt traps can cause fouling of
the plate heat exchanger.

External medium reservoir

If, for example, the necessary
capacity of the cold water outlet is
significantly less than the cooling
capacity generated by the chiller,
an increase in the medium content
is recommended. As an example,
the medium piping can be over­sized or an additional reservoir
installed to increase compressor
operating time.
A reservoir should, as a rule, be
provided if the minimum medium
volume is not reached.

Condensate connection

If the temperature falls below the
dew point, condensation will form
on the finned condenser during
heating operation.

A condensate pan should be in­stalled on the underside of the unit
to drain any condensate.

■

The condensate line to be in­stalled on-site must be installed
with a pitch of at least 2 %.
If necessary, fit vapour diffusion
tight insulation.

■

When operating the unit at
outdoor temperatures below
4 °C, care must be taken that
the condensate line is anti­freeze protected. The lower part
of the housing and condensate
pan is also to be kept frost free
in order to ensure permanent
draining of the condensate.
If necessary, fit supplementary
pipe heating.

■

After completed installation,
check that the condensate run
off is unobstructed and ensure
that the line is durably leak
tight.

NOTE

Cumulative ice formation in
the lower part of the finned
heated exchanger can develop
under certain weather con­ditions. To prevent this ice
formation, we recommend
keeping the heat exchanger
frost free on both sides using
a heating band for example.

Ensured discharge in the event of
leakage

Local regulations or environmen­tal laws, for example the German
Water Resource Law (WHG), can
require suitable precautions to pro­tect against uncontrolled draining
in case of leakage to provide for
safe disposal of escaping refrigera­tor oil or hazardous media.

NOTE

Malfunctions can result if the
minimum medium volume is
undercut.

7 Terminal connections

External enabling contact
Operating mode / Stand-By

In addition to being operated with
the controller or the cable remote
control, the unit can be switched
on (normal mode) and switched
off (Stand-By) over an external po­tential free contact (programmable
as opener or closer) (Figure 7).

The controller must be configured
if a closer is used for the external
enabling.

26

(See section "Configuration exter­nal enabling").
This enable is used for example to
realise standstill times at night or
for the activation/deactivation of
a building control system.

General fault signal
(Standard equipment)

The connection of a potential free
general fault signal, for exam­ple, for signalling or for further
processing to a building control
system is possible as standard
equipment. Use the respec­tive connection diagram for this
purpose and pay attention to the
maximum contact loads (Figure 8).

Winter pressure controller

Electrical components

Electric components and safety
equipment

Pressure switch cooling cycle HP
and LP

There is a high pressure switch
(HP) on the heat gas side within
the cooling cycle to switch off the
unit in the event of a temperature
increase.
A low pressure switch (LP) on the
suction side or in the compressor
switches off the unit if the
refrigerant charge is too low.

Differential pressure switch

The differential pressure switch is
installed parallel to the evaporator
in the medium circuit. It measures
the pressure differential between
the intake and outlet pressure and
switches the unit off when the
minimum flow volume is fallen
short of or with extremely large
flow volumes.

Thermal contacts
Condenser fans

The condenser fan's thermal con­tacts prevent overheating of the
motors.

Compressor thermal contact

The thermal contact is located
within the compressor and limits its
hot gas end temperature.

Phase sequence relay

The phase sequence relay controls
the direction of rotation for the
voltage supply. The controller will
not be enabled if the direction of
rotation is wrong.

Low noise fan control board

With a modulating output voltage,
the condenser fan's speed can be
adjusted to the condenser tem­perature and in this way hold the
noise level to a minimum.
The iCHiLL controller determines
the current condensation tempera­ture at the condenser through the
sensor Pb 3. The target value is
then regulated over the fan control
board.

Sensor Pb 1 medium intake

The sensor is located at the unit's
medium intake (system return).
It serves to capture the current
temperature to control the target
value.

Sensor Pb 2 medium outlet

The sensor is located at the unit's
medium outlet (system supply).
It serves to capture the current
temperature and regulate the anti­freeze protection temperature.

Sensor Pb 3 fan controller

The sensor is located on the cool­ing circuit's condenser. It detects
the current condensing tempera­ture in cooling mode for the low­noise fan controller.

Before

Leak testing

Leak testing is carried out after all
the pipes and fittings have been
connected.

1. Flush the system twice with
water.

2. Clean the sieve insert of the dirt
trap provided by customer.

3. Fill the system with water again
and vent the system at the
manual air bleeder.

4. Adjust the test pressure to
250 kPa (2.5 bar).

5. Check the connections after a pe­riod of 24 hrs for leaking water.
If water is visible, the connection
has not been secured.
Tighten the connection or make a
new connection.

6. After a successful leak test, re­move the excess pressure from
the medium line. If a water­glycol mixture is used, adjust
the non circulating pressure as
required.

commissioning

Filling the system

The system is filled on-site at the
filling and draining connection.

Anti-freeze protection for the medium

If a water-glycol mixture is used,
it is to be pre-mixed before being
put in the system. The desired con­centration is then to be checked.

Unit preliminary pressure for the
medium

The preliminary pressure of the
medium (without operation of the
circulation pump) varies within
the system. From the highest
point, the pressure increases by
approx.10 kPa (0.1bar) per metre
difference in altitude (geodetic
altitude). The value measured at
the highest point is identified as
the standstill pressure.

The position of the unit in the
system is decisive in the calculation
of the unit's preliminary pressure
(pressure of the manometer on
the unit installed by the customer).
The pressure is to be set to at least
70 kPa (0.7 bar)

■

If the unit is positioned at the
lowest point in the system,
the unit preliminary pressure
(=standstill pressure+geodetic
system altitude) must be set to

at least 70 kPa (0.7 bar) + 10
kPa (0.1bar) x geodetic system
altitude.

■

If the unit is positioned at the
highest point in the system,
the unit preliminary pressure
(=standstill pressure) must be
set to at least 70 kPa (0.7 bar).
Please note that the system
pressure at the lowest point
is increased by the geodetic
system altitude!

Bleeding the system

■

Air may still be in the pipe
lines after the leak test. This is
carried during operation of the
circulation pump to the next
highest point or to the cold
water drain. Here it is necessary
to vent again (Figure 10).

■

Also vent the pump if neces­sary.

■

The standstill pressure must
then be adjusted to the re­quired system pressure.

■

The preliminary pressure for the
diaphragm expansion vessel must
be adjusted individually to the
system layout, the volume of the
medium and the installation site.

■

If necessary, change the installa­tion site. For this, the manufac­turer's authorisation is required.

■

For cooling and heating sys­tems, the volume and the
preliminary pressure for the dia­phragm expansion vessel must
be adjusted to both operating
modes; integrate an additional
diaphragm expansion vessel in
the system if necessary.

Valves for hydronic balancing

■

The calculated excess pressure
in the pipe network layout at
the individual cold water outlets
must be adjusted in the pipe leg
regulating valves.

Safety valve

■

The safety valves and their cor­rect function must be checked.

■

The drain line for the valves are
to be checked for function and
leak tightness.

■

If necessary, change the in­stallation site. For this, the
manufacturer's authorisation is
required.

Additional checks

General checks

■

Checking that minimum clear­ances are correct.

■

Check the outlet possibility of
cooling and heating capac­ity over the cold or hot water
outlet (indoor unit).

Electrical checks

■

Checking electrical connections
for correct phase sequencing.

■

Function check of the enable
mode / Stand-By (option).

Checking the medium cycle

■

Check the circulating pump for
free flow.

■

Check that all valves are open.

■

Check the medium cycle.

■

Set the circulation pump’s flow
volume.

Checking the cooling cycle

■

Checking the cooling cycle for
adequate oil/coolant.

■

Check the cooling cycle for
leaks.

NOTE

The systems are equipped
with a phase sequence relay
which prevents the operation
of the controller if the phrase
sequence for the electric mains
connection is wrong.
The phrase sequence must be
corrected if the controller is
not activated during
commissioning.

NOTE

During manual bleeding, es­caped glycol mixtures must be
disposed of separately.

Commissioning

NOTE

Commissioning should only be
Carried out by trained person­nel and after certification to be
documented.

■

Observe the manuals for the

unit and all other components
when commissioning the entire
system.

Working test for cooling
mode

1. Switch the power supply on.

2. Open all shut-off valves if
necessary.

3. Switch the system and the cor­responding circulating pump on
to the highest stage.
The outlet temperature must lie
between +4 and +18°C.

4. Switch the unit on and select
the cooling operating mode.
If the return temperature is
warmer than the setting, the
compressor display will blink
and the compressor will begin
to work after approx. 3 to 5
minutes.

5. Please note that the supply
temperature at the nominal
medium flow lies approx. 5 K
below the return temperature.

- If the supply temperature falls
below the factory setting of
4°C, a fault signal is triggers. If
this is the case, a higher target
temperature must be selected.
If the spread is too great or too
small, the medium flow must
be checked.

6. Measure and record all the
required values in the commis­sioning report and check the
safety functions.

■

NOTE

Ice forms on the fins in heating mode as a consequence of the heat
absorption. The amount of ice depends on the percentage of humid­ity in the ambient air. Under certain cycles and temperature condi­tions, defrosting cycles are run through in which no heat capacity
can be generated. The following reduction factors for the defrosting
cycles must be taken into account even when planning the layout:
