APPLICATION GUIDELINES
SCROLL COMPRESSION PRINCIPLE
In a Performer® SH scroll compressor, the compression is performed by two scroll elements located in the upper part of the compressor.
Suction gas enters the compressor at the suction connection. As all of the gas fl ows around
and through the electrical motor, thus ensuring
complete motor cooling in all applications, oil
droplets separate and fall into the oil sump. After
exiting the electrical motor, the gas enters the
scroll elements where compression takes place.
Ultimately, the discharge gas leaves the compressor at the discharge connection.
The fi gure below illustrates the entire compression process. The centre of the orbiting scroll (in
grey) traces a circular path around the centre of
the fi xed scroll (in black). This movement creates
symmetrical compression pockets between the
two scroll elements. Low-pressure suction gas is
trapped within each crescent-shaped pocket as it
gets formed; continuous motion of the orbiting
scroll serves to seal the pocket, which decreases
in volume as the pocket moves towards the centre of the scroll set increasing the gas pressure.
Maximum compression is achieved once a pocket
reaches the centre where the discharge port is
located; this stage occurs after three complete
orbits. Compression is a continuous process: the
scroll movement is suction, compression and discharge all at the same time.

The scroll compressor application range is infl uenced by several parameters which need to be

These parameters and the main recommendations for good practice and safety devices are explained hereunder.

Danfoss Commercial Compressors, along with the
whole refrigeration and air conditioning industry,
shares today’s concern about the environmental
issues that are ozone depletion, global warming
and overall energy consumption. Usual HCFCs
refrigerant fl uids such as R22 are known to be implicated in these harmful phenomena, especially
ozone depletion due to their chlorinated content.
These substances are scheduled to be phasedout from production and use in coming years,

Additional points could infl uence the fi nal
choice:

• Standardisation of refrigerants and lubricants
• Refrigerant cost
• Refrigerant availability
in accordance with the international Montreal
Protocol (1984).
As a result, new chlorine -free molecules have been
recently developed and are now ready to replace
former fl uids. Among those refrigerants, the HFC
blend R410A is admitted by a great majority of
manufacturers to be the most promising in terms
of environmental impact, stability and effi ciency,

considerations
Successful application of scroll compressors is
dependent on careful selection of the compressor for the application. If the compressor is not
The working pressure in systems with R410A is
about 60% higher than in systems with R22 or
R407C. Consequently, all system components and
piping must be designed for this higher pressure
level.
Proper piping practices should be employed to
ensure adequate oil return, even under minimum
load conditions with special consideration given
to the size and slope of the tubing coming from
the evaporator. Tubing returns from the evaporator should be designed so as not to trap oil and to
prevent oil and refrigerant migration back to the
compressor during off -cycles.
In systems with R410A, the refrigerant mass fl ow
will be lower compared to R22/R407C systems.
To maintain acceptable pressure drops and acceptable minimum gas velocities, the refrigerant
piping must be reduced in size compared to R22

limits given in this manual. Poor performance, reduced reliability, or both may result.
/ R407C systems. Take care not to create too high
pressure drops or since in R410A systems the negative impact of high pressure drops on the system
effi ciency is stronger than in R22/R407C systems.
Piping should be designed with adequate threedimensional fl exibility. It should not be in contact
with the surrounding structure, unless a proper
tubing mount has been installed. This protection
proves necessary to avoid excess vibration, which
can ultimately result in connection or tube failure
due to fatigue or wear from abrasion. Aside from
tubing and connection damage, excess vibration
may be transmitted to the surrounding structure
and generate an unacceptable noise level within
that structure as well. For more information on
noise and vibration, see the section on: «Sound
and vibration management».
Suction lines
If the evaporator lies above the compressor, as
is often the case in split or remote condenser
systems, the addition of a pump-down cycle is
strongly recommended. If a pump-down cycle
were to be omitted, the suction line must have a
loop at the evaporator outlet to prevent refrigerant from draining into the compressor during off cycles.
If the evaporator were situated below the compressor, the suction riser must be trapped so as
to prevent liquid refrigerant from collecting at the
outlet of the evaporator while the system is idle,
which would mislead the expansion valve’s sensor (thermal bulb) at start-up.

Heat exchangers
When the condenser is mounted at a higher position than the compressor, a suitably sized «U»shaped trap close to the compressor is necessary
to prevent oil leaving the compressor from draining back to the discharge side of the compressor
during off cycle. The upper loop also helps avoid
condensed liquid refrigerant from draining back
to the compressor when stopped.
To obtain optimum effi ciency of the complete refrigerant system, optimised R410A heat exchangers must be used. R410A refrigerant has good
heat transfer properties: it is worthwhile designing specifi c heat exchangers to gain in size and
effi ciency.

Condenser
A sub-cooler circuit in the condenser that creates high sub cooling will increase effi ciency at
high condensing pressure. In R410A systems the
positive eff ect of sub cooling on system effi ciency will be signifi cantly larger than in R22/R407C
systems.
An evaporator with optimised R410A distributor
and circuit will give correct superheat at outlet
and optimal use of the exchange surface. This is
critical for plate evaporators that have generally
a shorter circuit and a lower volume than shell &
tubes and air cooled coils.
For all evaporator types a special care is required
for superheat control leaving the evaporator and
oil return.
Refrigerant charge limit Performer® SH compressors can tolerate liquid
refrigerant up to a certain extend without major
problems. However, excessive liquid refrigerant in
the compressor is always unfavourable for service
life. Besides, the installation cooling capacity may
be reduced because of the evaporation taking
place in the compressor and/or the suction line
instead of the evaporator. System design must be
such that the amount of liquid refrigerant in the
compressor is limited. In this respect, follow the
guidelines given in the section: “essential piping
design recommendations” in priority.
Furthermore, for good operation of the expansion device and to maintain good effi ciency in the
evaporator it is important to have a high degree
of liquid sub cooling. Without adequate sub cooling, fl ash gas will be formed at the expansion device resulting in a high degree of vapour at the
evaporator inlet leading to low effi ciency.
Use the tables below to quickly evaluate the required compressor protection in relation with the

Off -cycle migration Off -cycle refrigerant migration is likely to occur
when the compressor is located at the coldest
part of the installation, when the system uses a
bleed-type expansion device, or if liquid is allowed to migrate from the evaporator into the
compressor sump by gravity. If too much liquid
refrigerant accumulates in the sump it will saturate the oil and lead to a fl ooded start: when the
compressor starts running again, the refrigerant
evaporates abruptly under the sudden decrease
of the bottom shell pressure, causing the oil to
foam. In extreme situations, this might result
in liquid slugging (liquid entering the scroll elements), which must be avoided as it causes irreversible damage to the compressor.
Performer® SH scroll compressors can tolerate occasional fl ooded starts as long as the total system
charge does not exceed the maximum compressor refrigerant charge.

SYSTEM DESIGN RECOMMENDATIONS
Sump heater The surface sump heaters are designed to protect
the compressor against off -cycle migration of
refrigerant.
When the compressor is idle, the oil temperature
in the sump of the compressor must be maintained at no lower than 10 K above the saturation temperature of the refrigerant on the lowpressure side. This requirement ensures that
the liquid refrigerant is not accumulating in the
sump. A sump heater is only eff ective if capable
of sustaining this level of temperature diff erence.
Tests must be conducted to ensure that the appropriate oil temperature is maintained under
all ambient conditions (temperature and wind).
Note that below –5°C ambient temperature and a
wind speed of above 5m/second, we recommend
that the heaters be thermally insulated in order to
limit the surrounding energy losses.
Since the total system charge may be undefi ned,
a sump heater is recommended on all standalone compressors and split systems. In addition, any system containing a refrigerant charge
in excess of the maximum recommended system
charge for compressors requires a sump heater. A
sump heater is also required on all reversible cycle
applications.
SH180-240-300-380 initial start-up: For large
commercial platform initial start-up, it is not recommended to energize the crankcase heater in
advance, but quick starts may be needed to evacuate refrigerant in the system.
Then the heater must be energized whenever the
compressor is off to avoid liquid refrigerant entering the compressor.
Provide separate electrical supply for the heaters
so that they remain energized even when the machine is out of service (eg. Seasonal shutdown).
Surface sump heater accessories are available
from Danfoss (see section "Accessories").
SH090-105-120-140-161-184 initial start-up: Due
to light commercial platform compact design, it
is recommended to energize surface sump heater
in advance to remove refrigerant at initial start-up
only 6 hours in advance.

Pump-down cycle A pump-down cycle represents one of the most
eff ective ways to protect against the off -cycle migration of liquid refrigerant. Once the system has
reached its set point and is about to shut off , the
LLSV on the condenser outlet closes. The compressor then pumps the majority of the refrigerant charge into the condenser and receiver before
the system stops on the low pressure p ump-down
switch. This step reduces the amount of charge
on the low side in order to prevent off -cycle migration. The recommended low-pressure pumpdown switch setting is 1.5 bar below the nominal
evaporating pressure. It shall not be s et lower than
2.3 bar(g). For suggested wiring diagrams, please

In certain conditions, the discharge valve in the

be installed.
Tests for pump down cycle approval:
As the pump-down switch setting is inside the •
application envelope, tests should be carried
out to check unexpected cut-out during transient conditions (ie. defrost – cold starting).
When unwanted cut-outs occur, the low pressure pump-down switch can be delayed. In this
case a low pressure safety switch without any
delay timer is mandatory.

Liquid fl ood back
While the thermostat is off , the number of pres-•
sure switch resets should be limited to avoid
short cycling of the compressor. Use dedicated
wiring and an additional relay which allows for
one shot pump-down.
The pump-down allows to store all the refrigerant in the high pressure side circuit. On unitary or
close-coupled systems, where the system refrigerant charge is expected to be both correct and
defi nable the entire system charge may be stored
in the condenser during pump-down if all components have been properly sized.
During normal operation, refrigerant enters the
compressor as a superheated vapour. Liquid fl ood
back occurs when a part of the refrigerant entering the compressor is still in liquid state.
Performer SH scroll compressors can tolerate occasional liquid fl ood back. However system de-

Low ambient application
SPECIFIC APPLICATION RECOMMENDATIONS
Low ambient start-up
Low ambient operations
Under cold ambient conditions (<0°C), upon startup the pressure in the condenser may be so low
that a suffi cient pressure diff erential across the
expansion device cannot be developed to properly feed the evaporator.
As a result, the compressor may go into a deep
vacuum, which can lead to compressor failure
due to internal arcing and instability in the scroll
wraps. Under no circumstances should the compressor be allowed to operate under vacuum. The
low-pressure control must be set in accordance
with the table section "Low pressure" in order to
prevent this from happening.
The Performer® SH scroll compressor requires a
minimum pressure diff erential of 6 to 7 bar between the suction and discharge pressures to
force the orbiting scroll down against the oil fi lm
on the thrust bearing. Anything less than this differential and the orbiting scroll can lift up, causing
a metal-to-metal contact. It is therefore necessary
to maintain suffi cient discharge pressure in order
to ensure this pressure diff erential. Care should
be taken during low ambient operations when
heat removal from air-cooled condensers is greatest and head pressure control may be required for
low ambient temperature applications. Operation
under low pressure diff erential may be observed
by a signifi cant increase in the sound power level
generated by the compressor.
It is recommended that the unit be tested and
monitored at minimum load and low ambient
conditions as well. The following considerations
should be taken into account to ensure proper
system operating characteristics.
Expansion device: The expansion device should
be sized to ensure proper control of the refrigerant fl ow into the evaporator. An oversized valve
may result in erratic control. This consideration is
especially important in manifolded units where
low load conditions may require the frequent
cycling of compressors. This can lead to liquid
refrigerant entering the compressor if the expansion valve does not provide stable refrigerant
super-heat control under varying loads.
Early feeding of the evaporator and management
of the discharge pressure could help to attenuate
these eff ects.
Low pressure diff erentials can also cause the expansion device to «hunt» erratically, which might
cause surging conditions within the evaporator,
with liquid spillover into the compressor. This effect is most pronounced during low load conditions, which frequently occur during low ambient
conditions.
levels during low loading periods. A minimum of
5 K stable superheat is required.
Head pressure control under low ambient
conditions: Several possible solutions are avail-
able to prevent the risk of compressor to vacuum
and low pressure diff erential between the suction
and discharge pressures.
In air-cooled machines, cycling the fans with a
head pressure controller will ensure that the fans
remain off until the condensing pressure has
reached a satisfactory level. Variable speed fans
can also be used to control the condensing pressure. In water-cooled units, the same can be performed using a water regulator valve that is also
operated by head pressure, thereby ensuring that
the water valve does not open until the condensing pressure reaches a satisfactory level.
The minimum condensing pressure must be set
at the minimum saturated condensing temperature shown in the application envelopes.
Under very low ambient conditions, in which testing has revealed that the above procedures might
not ensure satisfactory condensing and suction
pressures, the use of a head pressure control valve
is recommended. Note: This solution requires extra refrigerant charge, which can introduce other
problems. A non-return valve in the discharge
line is recommended and special care should be
taken when designing the discharge line.
The superheat setting of the expansion device
should be suffi cient to ensure proper superheat

Due to the small volume of the brazed plate heat
exchanger, no pump-down cycle is normally required. The suction line running from the heat
exchanger to the compressor must be trapped to
avoid refrigerant migration to the compressor.
When using a brazed plate condenser heat exchanger, a suffi cient free volume for the discharge
gas to accumulate is required in order to avoid
excess pressure build-up. At least 1 meter of discharge line is necessary to generate this volume.
To help reduce the gas volume immediately after

SPECIFIC APPLICATION RECOMMENDATIONS
Water utilizing systems
Apart from residual moisture in the system after
commissioning, water could also enter the refrigeration circuit during operation. Water in the
system shall always be avoided. Not only because
it can shortly lead to electrical failure, sludge in
sump and corrosion but in particular because it
can cause serious safety risks.
Common causes for water leaks are corrosion and
freezing.
Corrosion: Materials in the system shall be compliant with water and protected against corrosion.
Freezing: When water freezes into ice its volume
expands which can damage heat exchanger walls
and cause leaks. During off periods water inside
heat exchangers could start freezing when ambient temperature is lower than 0°C. During on periods ice banking could occur when the circuit is
running continuously at too low load. Both situations should be avoided by connecting a pressure
and thermostat switch in the safety line.

Stopping sound level
Sound generation in a
refrigeration or air
conditioning system
SH compressors are equipped with a discharge
valve which closes at compressor shut down and
thus prevents the compressor from running backwards. This reduces the stopping sound to a metallic click caused by the closing valve.
Typical sound and vibration in refrigeration and
air conditioning systems encountered by design
and service engineers may be broken down into
the following three source categories.
Sound radiation: this generally takes an airborne
path.
When the pressure diff erence or gas fl ow at shut
down should be very low, this can delay the discharge valve from closing and lead to a longer
noise duration.
Mechanical vibrations: these generally extend
along the parts of the unit and structure.
Gas pulsation: this tends to travel through the
cooling medium, i.e. the refrigerant.
The following sections focus on the causes and
methods of mitigation for each of the above
sources.
FRCC.PC.007.B5.02

APPLICATION GUIDELINES
SOUND AND VIBRATION MANAGEMENT
Compressor sound radiation For sound radiating from the compressor, the
emission path is airborne and the sound waves
are travelling directly from the machine in all
directions.
The Performer® SH scroll compressor is designed
to be quiet and the frequency of the sound generated is pushed into the higher ranges, which
not only are easier to reduce but also do not generate the penetrating power of lower-frequency
sound.
Use of sound-insulation materials on the inside
of unit panels is an eff ective means of substantially reducing the sound being transmitted to
the outside. Ensure that no components capable
of transmitting sound/vibration within the unit
come into direct contact with any non-insulated
parts on the walls of the unit.
Mechanical vibrations
Vibration isolation constitutes the primary method for controlling structural vibration. Performer®
SH scroll compressors are designed to produce
minimal vibration during operations. The use of
rubber isolators on the compressor base plate or
on the frame of a manifolded unit is very eff ective in reducing vibration being transmitted from
the compressor(s) to the unit. Once the supplied
rubber grommets have been properly mounted,
vibrations transmitted from the compressor base
plate to the unit are held to a strict minimum. In
addition, it is extremely important that the frame
supporting the mounted compressor be of suffi cient mass and stiff ness to help dampen any
residual vibration potentially transmitted to the
Because of the Performer®’s unique design of a

Note: for parallel assemblies see specifi c recommendations in Performer® SH parallel application
guidelines FRCC.PC.008 (rigid mounting).
The tubing should be designed so as to both reduce the transmission of vibrations to other structures and withstand vibration without incurring
any damage. Tubing should also be designed for
three-dimensional fl exibility. For more information on piping design, please see the section entitled “Essential piping design considerations”.
Gas pulsation

The Performer® SH scroll compressor has been
designed and tested to ensure that gas pulsation
has been optimised for the most commonly encountered air conditioning pressure ratio. On heat
pump installations and other installations where
the pressure ratio lies beyond the typical range,
testing should be conducted under all expected

Each Performer ® SH scroll compressor is equipped
with two lif t rings on the top shell. Always use both
these rings when lifting the compressor. Use lifting equipment rated and certifi ed for the weight
of the compressor. A spreader bar rated for the

the weight of the compressor is also highly recommended. Always respect the appropriate rules
concerning lifting objects of the type and weight
of these compressors. Maintain the compressor in
an upright position during all handling manoeuvres (maximum of 15° from vertical).
Never use only one lifting lug to lift the compressor. The compressor is too heavy for the single lug to handle, and the risk is run that the lug
could separate from the compressor with extensive damage and possible personal injury as a
result.

When the compressor is mounted as part of
an installation, never use the lift rings on the compressor to lift the installation. The risk is run that
the lugs could separate from the compressor or
that the compressor could separate from the base
frame with extensive damage and possible personal injury as a result.
Never apply force to the terminal box with the
intention of moving the compressor, as the force
placed upon the terminal box can cause extensive damage to both the box and the components

System cleanliness The refrigerant compression system, regardless
of the type of compressor used, will only provide high effi ciency and good reliability, along
with a long operating life, if the system contains
solely the refrigerant and oil it was designed for.
Any other substances within the system will not
improve performance and, in most cases, will be
highly detrimental to system operations.
The presence of non-condensable substances
and system contaminants such as metal shavings,
solder and fl ux, have a negative impact on compressor service life. Many of these contaminants
are small enough to pass through a mesh screen
and can cause considerable damage within a
bearing assembly.
The use of highly hygroscopic polyolester oil in
R410A compressors requires that the oil be exposed to the atmosphere as little as possible.
Tubing Only use clean and dehydrated refrigeration-
grade copper tubing. Tube-cutting must be carried out so as not to deform the tubing roundness and to ensure that no foreign debris remains
within the tubing. Only refrigerant grade fi ttings
should be used and these must be of both a de-

Compressor connection
When brazing the compressor fi ttings, do not
overheat the compressor shell, which could severely damage certain internal components due
to excessive heating. Use of a heat shield and/
or a heat-absorbent compound is highly recommended. Due to the relatively sizable tubing and
fi tting diameters a double-tipped torch using
acetylene is recommended for brazing operation
on SH compressors.
For rotolock version compressors, solder sleeves
are available.
For brazing the suction and discharge connections, the following procedure is advised:
y
.Make sure that no electrical wiring is connected
to the compressor.
.Protect the terminal box and compressor
y
painted surfaces from torch heat damage (see
diagram).
y
.Remove the Tefl on gaskets when brazing ro-

not be exposed to the open air for extended
periods.

y
.Move the torch to area only long enough to

y
.Remove all remaining fl ux once the joint has

Remaining fl ux would cause corrosion of the
tubing.
Ensure that no fl ux is allowed to enter into the
tubing or compressor. Flux is acidic and can cause
substantial damage to the internal parts of the
system and compressor.
The polyolester oil used in SH compressors is
highly hygroscopic and will rapidly absorb moisture from the air. The compressor must therefore
not be left open to the atmosphere for a long period of time. The compressor fi tting plugs shall be
removed just before brazing the compressor. The
compressor should always be the last component
brazed into the system
Before eventual unbrazing the compressor or
any system component, the refrigerant charge
must be removed from both the high- and lowpressure sides. Failure to do so may result in serious personal injury. Pressure gauges must be
used to ensure all pressures are at atmospheric
level.

Important selection criteria include the driers
water content capacity, the system refrigeration
capacity and the system refrigerant charge. The

For new installations with SH compressors with
polyolester oil, Danfoss recommends using the
Danfoss DML (100% molecular sieve) solid core
fi lter drier. Molecular sieve fi lter driers with loose
beads from third party suppliers shall be avoided. For servicing of existing installations where
acid formation is present the Danfoss DCL (solid
core) fi lter driers containing activated alumina are
recommended.
Do not use a megohm meter nor apply power to
the compressor while it’s under vacuum as this
may cause internal damage.
The drier is to be oversized rather than under
sized. When selecting a drier, always take into ac-

For the initial charge the compressor must not
run and eventual service valves must be closed.
Charge refrigerant as close as possible to the
nominal system charge before starting the compressor. This initial charging operation must be
done in liquid phase. The best location is on the
liquid line between the condenser outlet and the
fi lter drier. Then during commissioning, when
needed, a complement of charge can be done
in liquid phase: slowly throttling liquid in on the
low pressure side as far away as possible from
the compressor suction connection while compressor is running. The refrigerant charge quan-
Insulation resistance must be higher than 1 megohm when measured with a 500 volt direct current megohm tester.
Each compressor motor is tested at the factory
with a high potential voltage (hi-pot) that exceeds
the UL requirement both in potential and in duration. Leakage current is less than 0.5 mA.
SH scroll compressors are confi gured with the
pump assembly at the top of the shell, and the
motor below. As a result, the motor can be partially immersed in refrigerant and oil. The presence of refrigerant around the motor windings

operations.
Vacuum or charge from one side can seal the scro lls
and result in a non-starting compressor. When
