How do IDVs work?

Figure 3: Intermediate Discharge Valve (IDV)

Danfoss Intermediate Discharge Valves (IDVs) are located close to the discharge side of the compressor. They reduce excessive compression of refrigerant under part-load conditions while maintaining the same cooling capacity. The IDVs open when discharge pressure falls below the built-in optimization point. They adapt the eort of the motor to the varying load and pressure conditions in the system, thus reducing the eort of the motor and its electrical consumption and improving the system’s seasonal energy eciency.

General Information

When choosing a refrigerant, dierent aspects must be taken into consideration:

• Legislation (now and in the future)

• Safety

• Application envelope in relation to expected running conditions

• Compressor capacity and eciency

• Compressor manufacturer recommendations & Guidelines

Additional points could inuence the nal choice:

• Environmental considerations

• Standardisation of refrigerants and lubricants

• Refrigerant cost

• Refrigerant availability

R410A

R410A is a HFC blend (R32: 50%; R125: 50%) with a zero Ozone Depletion Potential (ODP=0) and a Global Warming Potential of 1924/AR5 (2088/AR4). It is a near-azeotropic mixture with a temperature glide less than 0.2 K.

With its high net refrigeration eect coupled to a high density, the R410A has appeared in last decade to be the preferred refrigerant for use in commercial air conditioners and heat pumps.

R452B

R452B is a HFO/HFC blend (R32: 67%; R125: 7%; R1234yf: 26%) with a zero Ozone Depletion Potential(ODP=0) and a low Global Warming Potential (GWP: 676/AR5 ; 698/AR4). It is a near-azeotropic mixture with a temperature glide around 1 K.

R452B has very close capacities versus R410A and due to its very limited discharge temperature dierence it appears today as the best candidate for a direct drop in of R410A.

R452B is classied A2L with low ammability properties. Please refer to European regulations and directives about the use of refrigerant of the A2L safety group ( EN378, EN60335). Outside Europe refer to the local regulation.

R454B

R454B is a HFO/HFC blend (R32 :68.9%; R1234yf: 31.1%) with a zero Ozone Depletion Potential (ODP=0) and a low Global Warming Potential (GWP: 467/AR5; 466/AR4). It is a near-azeotropic mixture with a temperature glide around 1 K.

R454B has very close match to R410A in terms of capacity and discharge temperature dierence, and it oers better eciencies compared to R410A.

R454B is classied A2L with low ammability properties. Please refer to European regulations and directives about the use of refrigerant of the A2L safety group (EN378, EN60335). Outside Europe refer to the local regulation

Scroll compressors, DSH090 to DSH600 | Sound and vibration data

Sound and vibration data

Typical sounds and vibrations in systems can be broken down into the following three categories:

• Sound radiation (through air)

• Mechanical vibrations (through parts and structure)

• Gas pulsation (through refrigerant)

The following sections focus on the causes and methods of mitigation for each of the above sources.

Compressor sound radiation - Single

For sound radiating from the compressors, the emission path is air and the sound waves are travelling directly from the machine in all directions.

Mechanical vibrations

A compressor generates some vibrations that propagate into the surrounding parts and structure. The vibration level of a DSH compressor alone does not exceed 120µm peak to peak for DSH090 to DSH184, and 154µm peak to peak for DSH240 to DSH600. However, when system structure natural frequencies are close to running frequency, vibrations are amplied due to resonance phenomenon.

A high vibration level is damageable for piping reliability and generates high sound levels.

Design piping

General requirements

Proper piping practices should be employed to:

1.

Ensure adequate oil return, even under minimum load conditions (refrigerant speed, piping slopes…). For validation tests see section Manage oil in the circuit.

2.

Avoid condensed liquid refrigerant from draining back to the compressor when stopped (discharge piping upper loop). For validation tests see section Manage o cycle migration.

3.

Piping should be designed with adequate three-dimensional exibility to avoid excess vibration. It should not be in contact with the surrounding structure, unless a proper tubing mount has been installed. For more information on noise and vibration, see section Sound and vibration data.

Tandem and trio requirements (Static)

Tandem and trio use static oil balancing principle to equalize oil level between the compressors by gravity. This is ensured by a precise suction and oil equalization piping design.

The discharge line has no impact on oil balancing. It is shown with tee, to indicate that both left and right side discharge headers are possible.

By default, DSH tandems and trios are not factory-built. To complete an assembly in the eld, you will need:

• Tubings, according to specic outline drawings indicated in the following table.

• Manifolding accessory kit.

• Compressors.

Suction and oil equalization piping drawings must be respected (diameters, minimum straight lengths, …)

Suction washer position

Depending on manifold conguration, it is essential to equalize the pressure of compressor sumps. Hence, a suction washer must be added on certain compressors according to the table. Suction washers are included in tandem or trio accessory kits as described in the illustrations.

Figure 34: Suction washer position

By convention, the compressor order (No.1, No.2 ...) is dened counting from left to right, placed on the side facing the electrical boxes of the compressors (see example below on a trio)

NOTE:



Voltage range: Nominal voltage ± 10%. The voltage range indicates where the compressor can run in the majority of the application envelope. A boundary voltage supply which accumulates under specic conditions such as high ambiance, high superheat, or map boundary conditions, may lead to a compressor trip.

Voltage imbalance

The maximum allowable voltage imbalance is 2%. Voltage imbalance causes high amperage over one or several phases, which in turn leads to overheating and possible motor damage. Voltage imbalance is given by the formula:

IP rating

The compressor terminal box according to IEC60529 is IP54 for all models when correctly sized IP54 rated cable glands are used.

First numeral, level of protection against contact and foreign objects

5 - Dust protected

Second numeral, level of protection against water

4 - Protection against water splashing

Terminal box temperature

The temperature inside the terminal box must not exceed 70°C (158°F). Consequently, if the compressor is installed in an enclosure, precautions must be taken to avoid that the temperature around the compressor and in the terminal box would rise too much. A ventilation installation on the enclosure panels may be necessary. If not, the electronic protection module may not operate properly. Any compressor damage related to this will not be covered by Danfoss warranty. In the same manner, cables must be selected in a way that ensures the terminal box temperature does not exceed 70°C (158°F).

LRA (Locked Rotor Amp)

Locked Rotor Amp value is the higher average current as measured on mechanically blocked compressors tested under nominal voltage. The LRA value can be used as a rough estimation for the starting current. However, in most cases, the real starting current will be lower. A soft starter can be applied to reduce starting current (see section Soft

starts).

RLA (Rated Load Amperage)

The RLA values presented are simply calculated by dividing the maximum current before tripping at overload test conditions by 1.4.

MOC (Maximum Operating Current)

The max operating current is the amperage the compressor will draw when it operates at maximum load of operating envelope within the voltages printed on the nameplate.

Winding resistance

Winding resistance is the resistance between phases at 25°C (77°F) (resistance value +/- 7%). Winding resistance is generally low and it requires adapted tools for precise measurement. Use a digital ohm-meter, a “4 wires” method and measure under stabilised ambient temperature. Winding resistance varies strongly with winding temperature. If the compressor is stabilised at a dierent value than 25°C (77°F), the measured resistance must be corrected using the following formula:

Motor protection

DSH090 to DSH184

Compressor models DSH 090 to 184 are provided with internal overload motor protection to prevent against excessive current and temperature caused by overloading, low refrigerant ow or phase loss.

The protector is located in star point of motor and, should it be activated, will cut out all three phases. It will be reset automatically.

While not compulsory, an additional thermal magnetic motor circuit breaker is still advisable for either alarm or manual reset.

Then it must be set at the Max Operating Current value (MOC):

• When the motor temperature is too high, then the internal protector will trip.

• When the current is too high the thermal magnetic motor circuit breaker will trip before the internal protection therefore oering possibility of manual reset.

DSH240 to DSH600

Compressor models DSH240-295-381-485-600 are delivered with a pre-installed motor protection module inside the terminal box. This device provides ecient and reliable protection against overheating and overloading as well as phase loss/reversal.

The motor protector comprises a control module and PTC sensors embedded in the motor winding.

The motor temperature is being constantly measured by a PTC thermistor loop connected on S1-S2 . If any thermistor exceeds its response temperature, its resistance increases above the trip level (4.500 Ω) and the output relay then trips – i.e. contacts M1-M2 are open. After cooling to below the response temperature (resistance < 2.750 Ω), a 5-minute time delay is activated.

After this delay has elapsed, the relay is once again pulled in – i.e. contacts M1-M2 are closed. The time delay may be cancelled by means of resetting the mains (L-N -disconnect) for approximately 5 sec.

A red/green twin LED is visible on the module (except on DSH485-3). A solid green LED denotes a fault free condition. A blinking red LED indicates an identiable fault condition:

Figure 46: PTC Overheat

While not compulsory, an additional thermal magnetic motor circuit breaker is still advisable for either alarm or manual reset.

Then it must be set at the Max Operating Current value (MOC) :

• When the motor temperature is too high, then the internal PTC over temp. and module is activated.

• When the current is too high the thermal magnetic motor circuit breaker will trip before the module activate therefore oering possibility of manual reset.

Phase sequence and reverse rotation protection

Use a phase meter to establish the phase orders and connect line phases L1, L2 and L3 to terminals T1, T2 and T3, respectively.

DSH090 to DSH184

Compressor models DSH 090 to 184 incorporates an internal reverse vent valve which will react when the compressor is run in reverse and will allow refrigerant to circulate through a by-pass from the suction to the discharge. Although reverse rotation is not destructive for these models, it should be corrected as soon as possible. Repeated reverse rotation over 24 hours may have negative impact on the bearings.

Reverse rotation will be obvious to the user as soon as power is turned on: the compressor will not build up pressure, the sound level will be abnormally high and power consumption will be minimal. If reverse rotation symptoms occur, shut the compressor down and connect the phases to their proper terminals. If reverse rotation is not halted, the compressor will cycle o-on the motor protection.

DSH240 to DSH600

Use a phase meter to establish the phase orders and connect line phases L1, L2 and L3 to terminals T1, T2 and T3, respectively.

Compressor models DSH 240 to 600 are delivered with an electronic module which provides protection against phase reversal and phase loss at start-up.

The phase sequencing and phase loss monitoring functions are active during a 5-sec window 1 second after compressor start-up (power on L1-L2-L3).

Should one of these parameters be incorrect, the relay would lock out (contact M1-M2 open). The red LED on the module will show the following blink code (except on DSH485-3):

Check proper oil return

A

Lowest foreseeable evaporation, and highest foreseeable condensation. Minimum number of compressor running for 6 hours. For reversible system, perform test in both heating and cooling mode.

Oil level must be visible or full in the sight glass when the compressor is running and when all compressors of the circuit are stopped.

Top-up with oil, generally 3% of the total system refrigerant charge (in weight). Above 3% look for potential oil trap in the system. Integrate a function in control logic to run all compressors simultaneously in order to boost oil return (for more details see section Control logic) Oil separator can be added

Oil return in split systems

Since each installation is unique, test 1 and 2 can not fully validate the oil return. Oil level must be checked and adjusted at commissioning.

Oil level must be visible or full in the sight glass when the compressor is running and when all compressors of the circuit are stopped.

Pay special attention to “Piping design” Oil separator is strongly recommended, espacially in case of part load.

Table 27: Manage oil in the circuit - Test, criteria and solutions

Manage sound and vibration

Sound radiations

Mitigations methods: We can consider two means to reduce compressors sound radiations:

1.

Acoustic hoods are quick and easy to install and do not increase the overall size of the compressors. Acoustic hoods are available from Danfoss as accessories. Refer to the tables above for sound levels, attenuation and code numbers.

2.

Use of sound-insulation materials on the inside of unit panels is also an eective mean to reduce sound radiation.

Scroll compressors, DSH090 to DSH600 | Application

NOTE:



During compressor shut down, a short reverse rotation sound is generated. The duration of this sound depends on the pressure dierence at shut down and should be less than 3 seconds. This phenomenon has no impact on compressor reliability.

Gas pulsation

The compressor has been designed and tested to ensure that gas pulsation is optimized for the most commonly encountered air conditioning pressure ratio. Manifolded compressors are equivalents to lagged sources of gas pulsation. Therefore, pulse level can vary during time.

Mitigations methods: If an unacceptable level is identied, a discharge muer with the appropriate resonant volume and mass can be installed.

Mitigation Methods

1.

To ensure minimum vibrations transmission to the structure, strictly follow Danfoss mounting requirements (mounting feet, rails etc..). For further information on mounting requirements, please refer to section Design

compressor mounting.

2.

Ensure that there is no direct contact (without insulation) between vibrating components and structure.

3.

To avoid resonance phenomenon, pipings and frame must have natural frequencies as far as possible from running frequencies(50 or 60 Hz). Solutions to change natural frequencies are to work on structure stiness and mass (brackets, metal sheet thickness or shape…)

Manage Operating envelope

The Operating envelope for DSH scroll compressors guarantees reliable operations of the compressor for steady-

state operation.

Steady-state operation envelope is valid for a suction superheat within 5K to 30K range at nominal Voltage.

High and low pressure protection

Low-pressure (LP) and high-pressure (HP) safety switches must never be bypassed nor delayed and must stop all

the compressors.

LP switch auto restart must be limited to 5 times within 12 hours.

HP safety switch must be reset manually.

Depending on application operating envelope, you must dene HP and LP limits within operating envelope and pressure setting table above.

Discharge temperature protection

DSH240 to DSH600 include an integrated discharge temperature protection. Excessive discharge temperature will result in tripping of electronic module ouput relay.

This protection, eective for suction superheat above 5K (9°), should be considered as a compressor safety device and its purpose is not to ensure operation map control.

In case of basic map control by pressure switches that can not ensure totally that the compressor will remain in its operating envelope, an additionnal external discharge protection is required. (see below Figure 51: Discharge

temperature protection examples)

DSH090 to 184 have no integrated discharge temperature protection, an external protection is required.

This external protection device can be a thermostat or a temperature sensor. The discharge gas temperature protection must trip the power supply when it reaches the setting point to protect the compressor from overheating.

For R410A application the discharge gas protection should be set to open at a maximum discharge gas temperature of 135°C(275°F). The discharge gas thermostat accessory kit (code 7750009) is recommended.

For R452B/R454B application, the discharge gas protection should be set to open at a maximum discharge gas temperature of 150°C(302°F). A PT1000 is recommended.

The discharge gas thermostat or sensor must be attached to the discharge line within 150mm (5.91 inch) from the compressor discharge port and must be thermally insulated and tightly xed on the pipe (see Figure 52: Discharge

Manage o cycle migration

O -cycle refrigerant migration happens:

• when the compressor is located at the coldest part of the installation, refrigerant vapor condenses in the compressor.

• or directly in liquid-phase by gravity or pressure dierence. When the compressor restarts, the refrigerant diluted in the oil, or stored in evaporator, generates poor lubrication conditions, and may reduce bearings life time. In extreme situations, this leads to liquid slugging that can damage the compressor scroll set.

Requirement

• Compressor can tolerate occasional ooded start, but it should remain exceptional situation and unit design must prevent that this situation happen at each start.

• Right after start, liquid refrigerant must not ow massively to compressor

• The charge limit is a threshold beyond some protective measures must be taken to limit risk of liquid slugging and extreme dilution at start.

Surface Sump heater

The surface sump heater are designed to protect the compressor against o-cycle migration of refrigerant.

For DSH090-105-120-140-161-184, the surface sump heater is located on the compressor shell. For better standby energy consumption, Danfoss provides 48W and 80W two optional surface sump heater. The selection of surface sump heater could be refered to Table 32: surface sump selection principle

Figure 57: DSH090 to 184

Table 32: surface sump selection principle

For DSH240-295-381-485-600, the 56W surface sump seater is located below the sump, associated with a thermal insulation.

Figure 58: DSH240 to DSH485

The heater must be turned on whenever all the compressors are o. Surface sump heater accessories are available from Danfoss (see section Accessories and Spare parts).

Liquid line solenoid valve (LLSV)

A Liquid line solenoid valve (LLSV) is used to isolate the liquid charge on the condenser side, thereby preventing against charge transfer to the compressor during o -cycles. The quantity of refrigerant on the low-pressure side of the system can be further reduced by using a pump-down cycle in association with the LLSV.

Pump-down cycle

By decreasing pressure in the sump, pump down system:

• evacuates refrigerant from oil

• set the sump saturating pressure much lower than ambiance temperature and due to that, avoid refrigerant condensation in the compressor.

Wiring information Requirements

Protect the compressor from short circuit and overcurrent by a thermal magnetic motor circuit breaker set to Max.

• operating current or lower (see table in section Three phase electrical characteristics). For DSH090-105-120-140-161-184, phase sequence protection is strongly recommended.

• Compressor models DSH240-295-381-485-600 are delivered with a pre-installed motor protection module inside the terminal box that must be powered on.

• HP safety switch, DGT (only for DSH090 to DSH184) and electronic module relay output (M1-M2, only for DSH240 to DSH600) must be wired in the safety chain. Other safety devices such as LP can be either hardware or software managed.

• Provide separate electrical supply for the heaters so that they remain energized even when the machine is out of service (e.g. seasonal shutdown).

Soft starts

Soft starters are designed to reduce the starting current of 3-phase AC motors. Soft starters can be used on DSH compressor but, in order to ensure proper lubrication of compressor parts, the settings must ensure that the compressor start-up time is always less than 0.5 seconds.

Ramp-down must be set to minimum to ensure proper discharge valve closing.

In case of use with R454B or R452B make sure that the softstarter selected is compatible with A2L refrigerants.

Control logic

Safety control logic requirements

Table 36: Safety control logic requirements

(1)

Only for DSH240 to DSH600.

Cycle rate limit requirements

Danfoss requires a minimum compressor running time of 2 minutes to ensure proper oil return and sucient motor cooling.

Additionally, compressor must not exceed 12 starts per hour. 12 starts per hour must not be considered as an average, this is the maximum number of starts acceptable to keep a good regulation accuracy during low load.

Oil management logic recommendations

In some cases, oil management can be enhanced by control logic:

• If oil return test failed, a function can be integrated in control logic to run all compressors simultaneously during 2

minutes every hour in order to boost oil return. Time and delay can be ne-tuned by oil return test N°1 in section

Manage oil in the circuit. During oil boost, pay special attention to superheat management to avoid liquid ood

back.

• In trio system, after running long time in same state with 2 or 3 compressors, (1+2+3) or (1+2), (2+3) or (3+1), oil

unbalance may appears. A function can be implemented in control logic to stop all compressors during one minute every two hours in order to balance oil. Time and sequence can be ne-tuned during Oil balancing test in section Manage oil in the circuit.

Defrost logic recommendations / Reversible systems

In reversible systems, the defrost logic can be worked out to limit liquid ood back eect by:

1.

Running full load during defrost to share liquid refrigerant between all compressors.

2.

Reducing refrigerant ooding to compressor by transferring liquid refrigerant from one exchanger to the other before reversing valve thanks to pressures.

The following defrost logic combines both advantages:

Figure 63: Defrost logic advantages

In reversible systems, to ensure compressor reliability, the 4-way valve must not reverse when the compressor is stopped due to heating or cooling demand (stop on thermostat).

(1)

EXV Opening degree and time have to be set to keep a minimum pressure for 4 way valve moving. In any case, defrost logics must respect

EXV Opening degree and time have to be set to keep a minimum pressure for 4 way valve moving. In any case, defrost logics must respect requirements and tests described in sections Manage superheat and Operating envelope data.

requirements and tests described in sections Manage superheat and Operating envelope data.

Pump-down logic recommendations

Pump down is initiated prior to shutting down the last compressor on the circuit by de-energizing a liquid line solenoid valve or closing electronic expansion valve. When suction pressure reached the cut-out pressure, compressor is stopped, and liquid solenoid valve or electronic expansion valve remains closed.

Scroll compressors, DSH090 to DSH600 | Application

Two types of pump-down exist:

• One shot pump down (preferred): when last compressor of the circuit stops, suction presssure is decreased 1.5bar

(22psi) below nominal evaporating pressure with minimum of 1.7bar(g) (25psig). Even if suction pressure increases again, the compressor will not restart.

• Continuous pump-down: traditional pump-down, Compressor restarts automatically when suction pressure

increases up to 4 cycles maximum.

Non Return Valve (NRV)

DSH090 to DSH600 compressors integrate tight internal non return valve (INRV), therefore no external Non Return Valve (NRV) is needed.

Reduce moisture in the system

Excessive air and moisture

• can increase condensing pressure and cause high discharge temperatures.

• can create acid giving rise to copper platting.

• can destroy the lubricating properties of the oil.

All these phenomena can reduce service life and cause mechanical and electrical compressor failure.

Requirements

• The compressors are delivered with < 100ppm moisture level.

• At the time of commissioning, system moisture content may be up to 100ppm.

• During operation, the lter drier must reduce this to a level between 20 and 50ppm.

Solutions

To achieve this requirement, a properly sized and type of drier is required. Important selection criteria’s include:

• driers water content capacity,

• system refrigeration capacity,

• system refrigerant charge.

For new installations of compressors with polyolester oil, Danfoss recommends using the Danfoss DML (100% molecular sieve) solid core lter drier.

Assembly line procedure

Compressor storage

Store the compressor not exposed to rain, corrosive or ammable atmosphere between -35°C (-31°F) and 70°C (158°F) when charged with nitrogen and between -35°C (-31°F) and Ts max value (see section Pressure equipment

directive 2014/68/EU) when charged with refrigerant.

Compressor holding charge

Each compressor is shipped with a nominal dry nitrogen holding charge between 0.3bar (4 psi) and 0.7bar (10psi) and is sealed with elastomer plugs.

Respect the following sequence to avoid discharge check valve gets stuck in open position:

• Remove the suction plug rst

• Remove the discharge plug afterwards

An opened compressor must not be exposed to air for more than 20 minutes to avoid moisture is captured by the POE oil.

Scroll compressors, DSH090 to DSH600 | Application

Handling

Each Danfoss DSH scroll compressor is equipped with two lift rings on the top shell.

• Always use both these rings when lifting the compressor.

• Use lifting equipment rated and certied for the weight of the compressor or compressor assembly.

• A spreader bar rated for the weight of the compressor is highly recommended to ensure a better load distribution.

• The use of lifting hooks closed with a clasp is recommended.

• For tandem and trio assemblies, use a spreader bar and all compressor rings as shown in picture below.

• Never use the lift rings on the compressor to lift the full unit.

Maintain the compressor in an upright position during all handling manoeuvres (maximum of 15° from vertical).

Figure 67: Handling

Piping assembly

Good practices for piping assembly is a pre-requisite to ensure compressor life time (system cleanliness, brazing procedure etc.)

Table 37: System cleanliness

Brazing procedure:

• Brazing operations must be performed by qualied personnel.

• Make sure that no electrical wiring is connected to the compressor.

• To prevent compressor shell and electrical box overheating, use a heat shield and/or a heat-absorbent compound.

• Clean up connections with degreasing agent

• Flow nitrogen through the compressor.

• It is recommended to use double-tipped torch using acetylene to ensure a uniform heating of connection.

• For discharge connections brazing time should be less than 2 minutes to avoid NRVI damages if any.

• To enhance the resistance to rust, a varnish on the connection is recommended.

DSH compressors connectors are made of steel copper coated, which benet to protect against corrosion and facilitate adhesion during brazing operation.

Scroll compressors, DSH090 to DSH600 | Application

As per standards practice in the refrigeration industry, Danfoss Commercial Compressor recommend to use of silver cadmium free solder alloy and ux (added or ux coated rods). The signicant silver content in these brazing alloy will help the brazing operation, providing an excellent uidity and a limited heating temperature. It will bring also a good resistance to corrosion, a proper elongation compatible with system vibration, and good behavior under thermal variation improving the strength of connection and limiting fractures and refrigerant leaks. (Crucial with A2L refrigerants) A typical content of 34% Ag (Silver) is recommended by Danfoss.

The use of self-ux alloys (as phosphorous alloys) is not recommended by Danfoss. This type of brazing require a higher working temperature, that may overheat the connectors, damaging the thin layer of copper ,resulting in phosphides creation and joint zone embrittlement.

For more detailed information see “ Brazing technique for compressors connectors" AP192186420580.

Figure 68: Brazing procedure

Before eventual un-brazing of the compressor or any system component, the refrigerant charge must be removed and the installation vacuumed (especially with A2L refrigerants).

System pressure test and leak detection

The compressor has been strength tested and leak proof tested (<3g/year) at the factory. For system tests:

• Always use an inert gas such as Nitrogen or Helium.

• Pressurize the system on HP side rst then LP side.

• Do not exceed the following pressures indicated in table below

Table 38: System pressure test and leak detection

(1)

The maximum pressurizing speed must be respected to ensure pressure equalization between LP and HP side over scroll elements.

Vacuum evacuation and moisture removal

Requirements:

• Never use the compressor to evacuate the system.

• Connect a vacuum pump to both the LP and HP sides.

• Evacuate the system to a pressure of 500 μm Hg (0.67 mbar/0.02 in.Hg) absolute.

Scroll compressors, DSH090 to DSH600 | Application

Recommendations:

• Energized heaters improve moisture removal.

• Alternate vacuum phases and break vacuum with Nitrogen to improve moisture removal.

For more detailed information see “Vacuum pump-down and dehydration procedure” TI-026-0302.

Refrigerant charging

Initial charge:

• For the initial charge, the compressor must not run.

• Charge refrigerant as close as possible to the nominal system charge.

• This initial charging operation must be done in liquid phase between the condenser outlet and the lter drier.

If needed, a complement of charge can be done before evaporator, in liquid phase while compressor is running by slowly throttling liquid in.

Never bypass safety low pressure switch.

For more detailed information see “Recommended refrigerant system charging practice“ AP000086421422.

Dielectric strength and insulation resistance tests

Several tests have been performed on each compressor at the factory between each phase and ground.

• Dielectric strength test is done with a high potential voltage (hi-pot) of 2Un +1000V AC at least, and leakage

current must be less than 5 mA.

• Insulation resistance is measured with a 500 V DC megohm tester and must be higher than 1 megohm.

Recommendations:

• Additional dielectric test is not recommended as it may reduce motor lifetime. Nevertheless, if such as test is

necessary, it must be performed at a lower voltage.

• Insulation resistance test can be done.

• The presence of refrigerant around the motor windings will result in lower resistance values to ground and higher

leakage current readings. Such readings do not indicate a faulty compressor. To prevent this, the system can be rst operated briey to distribute refrigerant.

Do not use a megohm meter nor apply power to the compressor while it is under vacuum as this may cause internal damage.

Commissioning

Preliminary check

Check electrical power supply:

• Phase order: Reverse rotation is obvious if the compressor do not build up pressure and sound level is abnormal

high. For DSH090-184 compressors equipped with internal reverse vent valve which can protect compressor without damage within duration below 24h. For more details refer to section Phase sequence and reverse rotation protection.

For DSH240 to DSH600 compressors equipped with an electronic module, reverse rotation will be automatically detected. For more details refer to section Motor protection.

• Voltage and voltage unbalance within tolerance: For more details refer to section Motor voltage.

Scroll compressors, DSH090 to DSH600 | Application

Initial start-up

• Surface sump heaters must be energized at least 6 hours in advance to remove refrigerant.

• A quicker start-up is possible by “jogging” the compressor to evacuate refrigerant. Start the compressor for 1

second, then wait for 1 to 2 minutes. After 3 or 4 jogs the compressor can be started. This operation must be repeated for each compressor individually.

System monitoring

The system must be monitored after initial startup for a minimum of 60 minutes to ensure proper operating characteristics such as:

• Correct superheat and subcooling.

• Current draw of individual compressors within acceptable values (max operating current).

• No abnormal vibrations and noise.

• Correct oil level.

If Oil Top-up is needed, it must be done while the compressor is idle. Use the schrader connector or any other accessible connector on the compressor suction line. Always use original Danfoss POE oil 160SZ from new cans. For more detailed information see “Lubricants lling in instructions for Danfoss Commercial Compressors”

AP000086435866.

Dismantle and disposal

Danfoss recommends that compressors and compressor oil should be recycled by a suitable company at its

site.
