''Cooling means the transfer of thermal heat from a place where it is unwanted to a plaсewhere if does not disturb"

This is how the fаther of modernаir.сonditioning and refrigerationsystems defined the сooIingproсess' But in order to transferthermal heat from one p|aсe toanother, а trаnsport medium isrequired that аbsorbs the heаt atthe p|aсe where it is not wаntedand delivers it to the plaсe whereit does not disturb. Тhis is themain tаsk of any refrigerant,irrespeсtive of type, thermаI andсhemiсal properties orсomposition' No more, no less.Тhe driving forсe thаt makes therefrigerant move around in therefrigeration system is theсompressor' with the асtuаI heattransfer tаking plaсe in theevaporаtor (instаIled at the pIасewhere the heаt is unwanted)аndthe сondenser (instalIed at theрlасe where the heаt does notdisturb)' So it beсomes сIeаr thаtrefrigerants are essentia] mediаfor the funсtionаIity of anyrefrigeration system and shouldbe treated аs suсh.

Тhe purpose of this RefrigerаntHandling Guide is to assist youto proteсt both your investmentand the environment, and to pro-mote sаfetцonboаrd. !n addition,it сontains a refrigerаnt Iog thathelps you to асhieve improvedсontrol over your refrigera.tion сosts. continuous Ioggingof refrigerant сonsumption isrequired by some authorities(refer to the table on page 't5 inthis guide).

U1llт0вREFвIGЕЕAтION sERvlсЕ

Praсtiсal adviсe for safe and environmentally sound сharging and reсovery work on refrigeration

maсhinery:

1' Read the MаteriaI Safety Data Sheets (]vlsDs) on aI| сompounds inсIuding refrigerant and oil that you are

Iikely to сome in сontaсt with.

Refrigerant MSDS are avai|able from Unitor's Internet web site (www.unitor.сom).

2. Never overfill recovery сylinders. OverfiIling may сause the reсovery сyIinder to explode.

Safety сodes гeсommend that recovery сy|inders aгe not fi||ed over B0% of their vo|ume with |iquid (the remаining

20% is used for thermal expansion). Use weighing sсa|e for fi|ling сontro|. |f the reсovеry unit stops on high

pressure this is an indiсation of overfi|ling.

3' Use onIy approved reсovery сylinders.

Do not use the reсovery unit с|ose to an area with combustible substanсes.

4' Do not mix refrigerants in a reсovery сyIinder.

5. Keep the lengths of reсovery hoses аs short aЬ possible аnd when inсreаsed throughput is required use

Iаrger diameter hoses.

6' The key to quiсk reсovery is to reсover the |iquid refrigerant first.

The Unitor reсommended reсovery set-up for both reсovery as we|l аs сharging operаtions is shown on the sоhematiс

5. RЕFRIGЕRANт QUALIтY AND lTs IMPAст 0N RЕFRIGЕRAтIoN MAсHINERY

|n oгder to aIIow troub|e.free and safe operation of гefгigeration systems, refrigerants must сomp|y with сertain qua|ity

standards - just аs сomprеssors, the сontroI systems, the piping and othеr essentia| сomponents have to meet speсifiс

qua|ity standards. A major qua|ity aspeсt with гegards to refrigerants is their purity' Еspeсia||y the moisture сontent in the

refrigerant is of great importаnсe: too muсh moisture can сause serious operationa| prob|ems. It is the invisib|e moisture or

water vapour that сan сause grеatest troub|e in any refrigeration system. A drop of watеr may |ook harm|ess enough, but to a

refrigeгation system it is enemy number one, as it is vеry easy to get in (e.g' through sub-qua|ity refrigerant сontaminated

with moisture), but extreme|y hard to гemove again. lf not e|iminated, it сan сause а great dea| of diffiсu|ty.

|vOlsTURЕ |N A RЕFRIGERATION SYSТЕM MAY сAUsЕ FOUR ТYPЕs oF PROBLЕMS:

Freeze ups

Freeze ups oссUг Wnen moisture, piсkеd up by the refrigerant starts to freeze, bui|ding.iф'сrysta|s that b|oсk the refrigerant

passage in nаrrow passageways, for example in the expansion va|ve. Тhis effeсt is сaI|ed intermittent сoo|ing, as the

сompressor after а while stops due to the bloсkage in the expansion va|ve and starts again when the iсe сrysta|s have

me|ted and a||owed the гefrigerant to pass through again. Тhis is a periodiсa| proсess of сonstant freezing and me|ting of the

moisture inside the system, сausing periodiсa| stop/start operation of the сompressor.

Corrosion

Motsture alone in form of water сan сause сorrosion, however, moisture p|us a refrigerant сontaining ChIorine (|ike for

examp|e the HCFC R-22 and it.s mixtuгes) сreates muсh more serious сorrosion, as the Chlorine wi|| s|ow|y hydrolyse with

the wаter аnd form Hydroсh|oriс Aсid (HC|) whiсh is aggressive to most metals. Heat adds signifiсantly to the problem by

aссe1eгating the aсid4orming proсеss. When it сomes to the HFC refrigerants, it is the oi| (espeсia||y po|yo|ester oils thаt are

very hygrosсopiс) that may deсompose at high temperatures forming aggressive Hydrofluoriс aсid with the moisture

сontained in the refrigerant.

Oi l s ludging

As refrigeгation oiI is high|y hydrosсopiс, it rapid|y аbsorbs moisture. Еspeсia|ly moisture сhanged into aсid from the

hydгo|yses with a refгigerant (see abovе) сan bе vеry dangеrous, as it emu|sifies with the refrigeration oi| io form aggressive

oi| s|udge that greatly reduсes it's |ubriсation propeгties, whiсh сan resu|t in serious сompressoг dаmage.

Sludge formation

When sludge foгmation is pгesent, the metal|iс suгfaсe is еatеn awаy due to high aсid сontеnt inside the system, and a so|id,

detaсhab|e produсt is formed. |t exists аs s|imy Iiquids, fine powders and granu|ar or stiсky so|ids and is сommonly known as

s1udge. Тhis sIudge сan сause a variety of prob|ems suсh аs b|oсkages of fine strainers, expansion va|ves and сapil|ary

tubes. And bесause sludge usua||y сontains aсid, it сan aIso be strongly сorroslve.

",' {3rc}t*Ctyagjr i*vrstmФ{'t .*

To reсtify prob|ems сaused by too muсh moisture inside refгigerаtion systems сan be a сost|y exerсise. lf the moisture enteгs

the system with the refrigerant it wi|| lead to сontinuous сost|y repairs that reсtify the сonsequenсes but do not eltтninate the

сause.

It is therefore important that refrigerants сomp|y with appropriate qua|ity standards with regards to their puгity.

In order to ensure tгoub|e-freе and save operation of your onboard refrigeration mасhinery, a|l.refrigerants supp|ied by Unitor

throughout the woгld сomp|y with the stringent AR| 700-1999 standard that defines and benсhmаrks the purity of thesе

substanсes. Тhe standard e.g. demands the moistuгe сontent to be |ess than .l0 ppm.

The Unitor reсommended reсovery set-up for both, reсovery as we|l as сharging operation (P|еase see page 7).

Guidelines on Refrigeration Oils

Lubriсant se|eсtion for a гefrigeгation system is сritiсa| not on|y for the сompressor but also to ensure thаt the oi| does not

separate from the refгigeгant gas in any paгt of the p|ant.

|f the oi| type or supp|y manufасtuгeг is сhanged, inсompatibi|ity and henсe poor misсibitity within the p|ant сan сause

problems.

With the wide range of minera| and synthetiс produсts on the mаrket, сoup|ed with differеnt additive teсhnology, it is vita||y

importаnt to оheсk oi| misсibility prior to top-up with a different grade oiI. The a|ternative is to drain the oi| сomp|etely from a

refrigeгation system, whiсh сan be very diffiсu|t or even impossib|e without strenuous proсedures, During waгranty,

сomprеssor and/or system designers oftеn prohibit the use of non-approved refrigeration oi|s.

0il TestingA field test of oi| сan be done by visua||y inspeсting the oi| аnd use an oil aсid test kit to determine if the system has been

eхoosed to moisture. '} ],, 1-\1l]:

Oi| samp|es сan a|so be sent to a |aboratory for ana|ysis; this routine requires с|ean samp|e bottIes and is used for systems

сontaining large quantities of oi|.

0iI Changing ProсeduresRefеr to mаnufaсturers reсommendations on oi| сhange interva|s. Тhese may be annua||y or сou|d be more frequent if the oil

beсomes dark or сloudy.

A good ruIe is to renew the oi| if a majoг serviсe or гepair has been donе to the сompгessor or the system

Foг сhanging the oi| in a standаrd сondensing unit, it is normal to rep|асe the oi| сharge in the сompressoг сгаnkсase. |t is

also гeсommended to сIean or сhange the oiI fi|ter (if appliсab|e) and the refrigeгant drier fi|ter сorеs at the same time.

o|L сHARGING

Proсedure is as fo|lows:1. Run pump down and shut down the unit

2. C|ose the serviсe va|ves on the сompressor

3. Ensure that any сrаnkсase oi| heaters are switсhеd off

4' Drain oil сareful|y fгom the сompressor сrankсase

5. |f the oi| has been drained out with the сompressor prеssurised, new oiI саn be оharjЪd with an oi|-fi||ing pump

сapаb|e of working against pressure

6. Fit the oiI pump to the oi| сontainer aссording to manufасturers instгuctions, attaсh pump to сompressor with a

сharging hose and |eаve the hose сonneсtion to сompгessor |oose. Pump oi| into the сharging hose unti| it is fi|led

This is nесessary to e|iminate air from entering into the system and to еnsuгe proper pump funсtioning when

working against a pressurised system

lf the сompressor has been opened for inspeсtion or repair

т ' Еnsure thаt the сomprеssor сrankсase is cIean

B' Run deep VaсUUm on the сompressor using a Vaсuum pump, preferably down tо'Q00 miсгon

9. Charge oiI using the vaсuum to suоk up the oiI from the сontаiner into the сrankсase

10. Remembeг to switсh on the сrankсase oi| heater if app|iсab|e and a||ow time for the oi| to be heаted before the unit

is put baсk in operation

Used refгigeгation oil must be returned to a waste reсeption faсility.
