R-401A: A retrofit blend for R-12 refrigeration systems. The pressureand system capacity match R-12 when the blend is running in a 10°Fto 20°F evaporator, and there is typically an 8°F temperature glide inthe evaporator. Applications: direct expansion refrigeration and airconditioning systems designed for R-12 or R-500; good success in anysize system, minor adjustment of controls needed. Discharge pressureincreases compared to R-12, also slight increase in dischargetemperature, however the increases are not as severe as some otherretrofit blends. There is a drop in capacity at lower temperatures. R-152a content, an HFC, hurts the miscibility with mineral oil. It isrecommended to change some of the oil to alkylbenzene unless thesystem is small and running at higher evaporator temperatures.

R-401B: Similar to R-401A except higher in R-22 content. This blendhas higher capacity at lower temperatures (matches R-12 around -30°F), and also provides a closer match to R-500 at air conditioningtemperatures.

R-409A: A retrofit blend for R-12 refrigeration systems. The pressureand system capacity match R-12 when the blend is running in a 10°Fto 20°F evaporator, and there is typically 13°F temperature glide in theevaporator. Applications: direct expansion refrigeration and airconditioning systems designed for R-12 or R-500; good success in anysize system, minor adjustment of controls needed. Discharge pressureand temperature increases compared to R-12, which may be a problemin very hot ambient conditions. Capacity holds well into lowerapplication temperatures (-30°F). R-409A mixes well with mineral oildown to 0°F. As a result it may not be necessary to change oil insystems which do not run colder than 0°F in the evaporator (below 0°Falkylbenzene should replace some mineral oil).

R-414B: A retrofit blend for R-12 refrigeration and air conditioningsystems as well as automotive air conditioning systems. The pressureand system capacity match R-12 in 40°F to 50°F evaporators, and thedischarge pressure in hot condensers is only 5 to 10 psi higher than R-12 (a benefit in automotive AC and warmer refrigeration environments).The temperature glide runs about 13°F in the evaporator. The additionof isobutane to this blend significantly improves mineral oilcompatibility, particularly for high viscosity oils used in auto AC.

R417C: An HFC-based retrofit blend for R-12 and all HCFC retrofitblends intended for R-12 applications (for example, R-414B). Thissecond-generation blend contains a hydrocarbon additive and thereforecan be used with existing mineral oil or alkylbenzene.

General Provisions for Automotive Retrofit Blends: Automotive airconditioning retrofitting is governed by Section 609 of the Clean AirAct. The specific provisions of this section which apply to automotiveAC retrofit blends are 1) you can't top off R-12 with a blend, the originalcharge must be recovered first, 2) new fittings must be installed on thecar which are unique and specific to the blend being used, and 3) whenusing blends that contain R-22 the system must have nylon barrierhoses installed to prevent leakage. In stationary refrigeration systems running in high ambienttemperatures the use of an automotive blend can relieve problemsassociated with high discharge pressures, however capacity will suffercompared to R-12, especially as evaporator temperatures get lower.

R-134a: This HFC refrigerant has been the standard OEM choice forhousehold appliances, small self-contained refrigeration units, verylarge chillers, and automotive air conditioning. It is also being used asthe heat transfer fluid in secondary loop systems. R-134a is acomponent in many refrigerant blends on the market, including thenew lower GWP blends. Application Temperature Range: R-134a performance suffers atlower evaporator temperatures. In general it is not applied attemperatures below -10°F, and it is not necessarily the mosteconomical overall choice in some other applications. Traditional R-12type applications have adopted several products as alternatives,including R-134a, R-22, R-404A/R-507, and numerous retrofit blends.Lubrication: R-134a requires polyolester (POE) lubricants, primarilyfor their ability to mix with HFC refrigerants. Traditional mineral oilsand alkylbenzene do not mix with HFCs and will cause compressorfailures. In addition, automotive air conditioning systems may also usepolyalkylene glycol (PAG) lubricants (not typically seen in stationaryequipment).

Both POEs and PAGs will absorb moisture, and hold onto it, to a muchgreater extent than traditional lubricants. The moisture will promotereactions in the lubricant as well as the usual problems associatedwith water (corrosion, acid formation, etc.). The best way to dry a wetHFC system is to use a filter drier – run the system and change thedrier – instead of relying on evacuation to clear the water.Retrofitting Considerations: Equipment built for R-12 will be sized abit too small compared to equipment built for R-134a. In order to do thesame job, an R-134a system will need a larger compressor and largerheat exchangers. As a result, a system that is retrofitted from R-12 toR-134a will have lower capacity (run longer) and will probably develophigher head pressures (not enough condenser area). The lubricant willalso need to be flushed and replaced with POE.

R-11: Used in large, low pressure centrifugal chillers. This type ofchiller provides a very large amount of chilled water for air conditioningpurposes (office buildings, hotels, etc.) at the lowest operating costcompared to any other type of air conditioning system. R-11 productionwas phased out in 1995 but reclaimed R-11 is still available. Older R-11 chillers can continue to be serviced with available R-11 or beretrofitted to R-123 with engineering support from the equipmentmanufacturer.

R-113: Used in commercial and industrial air conditioning andindustrial water chillers. It is typically employed in an R-11 centrifugalchiller to generate less capacity to better match load conditions. It isnot possible to use solvent grade 113 for refrigeration purposesbecause of contaminants or additives used for solvents.

R-114: Before its production phaseout in 1995, it was used in positivepressure centrifugal chillers for air conditioning and industrial processcooling, as well as for air conditioning in very high ambienttemperature conditions. Its very good chemical stability made it usefulin highly corrosive applications, such as for shipboard chillers. Goodhigh temperature stability along with lower vapor pressures made it agood choice for high ambient air conditioning, for example in steel millcranes. Some applications have converted to R-124.

R-13B1 has properties that allow it work well in low temperaturerefrigeration systems with application temperatures from -40°F downto -60°F. R-13B1 was used in applications colder than R-22 whilemaintaining reasonable operating pressures, good capacity, and lowerdischarge temperatures in standard refrigeration equipment designs. Inmost cases, R-13B1 systems can be retrofitted to R-403B withadjustments in charge size, capillary tube length, and will result inlower suction pressures. The evaporator will operate in a vacuum whenthe low side temperature is below -55°F. The original lubricants can beused with R-403B, along with any additives the manufacturer mayrecommend.

R-12: Before its production phaseout in 1995, it was used in a varietyof applications from small hermetic refrigeration systems up throughlarge, positive pressure chillers. It was long-time industry standard forautomotive air conditioning, kitchen appliances, high/medium/lowtemperature refrigeration, and many other commercial and industrialapplications. Limited quantities of reclaimed R-12 is still available forservice of installed equipment.

R-22: The predominant refrigerant installed in residential andcommercial air conditioning and some very large centrifugal chillers forair conditioning and industrial process cooling. It has also beeninstalled more in refrigeration since the phaseout of CFCs, both as apure refrigerant and in blends. R-22 can no longer be used in newequipment, but available product can be used to service existingsystems.

R-123: Developed to replace R-11 in low pressure centrifugal chillers.New R-123 equipment has been engineered with the correct materialsof construction and sized properly for the intended application.Retrofitting existing R-11 chillers to R-123 may require replacement ofseals, gaskets, and other system components to obtain the correctoperation conditions and prevent leaks.

The ASHRAE safety rating for R-123 is B1, which indicates that lowerlevels for personal exposure are allowed in normal daily operation andservice conditions. Extra precautions and machinery roomrequirements must be observed (specific requirements are spelled outin ASHRAE Standard 15, Safety Code for Mechanical Refrigeration).

R-124: Used in refrigeration blends, primarily those used for R-12 typeapplications. Also used by itself to replace R-114 in chillers or highambient air conditioning applications, and for sterilant gasformulations.

R-407A: Has properties very similar to R-22 in refrigeration equipment.It has become a popular choice in the supermarket and refrigerationmarkets for retrofitting as well as new installations. Operatingpressure/temperature in the evaporator, run-time capacity, and flowcharacteristics through tubing and valves make this blend the closestproperty match to R-22 at lower evaporator temperatures.

R-407C: Has properties very similar to R-22 in air conditioningequipment and in medium temperature refrigeration. Operatingpressure/temperature in the evaporator, run-time capacity, and flowcharacteristics through tubing and valves make this blend the closestproperty match to R-22 for retrofitting at AC conditions.

R-407F: Has properties very similar to R-22 in refrigeration equipment.This blend is similar to R-407A, however it will generate higherdischarge temperatures.

R-410A: Used in new air conditioning and heat pump equipment. Thecomponents nearly form an azeotrope, which means it has extremelylow temperature glide and almost no fractionation potential. Thisblend has about 60% higher pressure than R-22 in air conditioningapplications, and therefore is only allowed to be used only in newequipment specifically designed to handle the pressure. Systemsdesigned for R-410A will have smaller components (heat exchangers,compressor, etc.) to perform the same cooling job compared to R-22.POE lubricant is required.

R-290: Propane (a hydrocarbon) used as the primary refrigerant insmall, stand alone refrigeration appliances such as drink machines anddisplay coolers. Propane is flammable and therefore is only allowed tobe used in new equipment that has been specially designed to reducethe risk of fire. In applications for which it is approved, charge size islimited. Follow all OEM guidelines for safe charging, and servicepractices.

R-422 Blends: With increased regulatory pressure on leak repair andrecordkeeping for HCFC refrigerants, the R-422 series of refrigerantsoffer an HFC-based retrofit solution that can be used with existingrefrigeration oils. Since no single refrigerant blend can replace R-22 inall applications, the R-422 series offers the best range of choices forretrofitting.

R-422B: A retrofit blend that is designed to match R-22 in airconditioning applications. There is a slight reduction in capacity whichwould result in slightly longer run times. Systems that were previouslyretrofitted to R-417A can operate with a replacement charge of R-422B. The hydrocarbon component in R-422B helps promote oil returnin systems containing mineral oil or alkylbenzene. Although HFCrefrigerants won't mix with these oils, the hydrocarbon componentthins the mineral oil and keeps it moving around the loop. Morecomplicated piping arrangements or large hold-up volumes mayrequire the addition of POE.

R-422C: A retrofit blend that is designed to match R-502, R-404A/507refrigeration systems. Equipment that was previously retrofitted withR-402A/B or R-408A can operate with a replacement charge of R-422C.The hydrocarbon component in R-422C helps promote oil return insystems containing mineral oil or alkylbenzene. Although HFCrefrigerants won't mix with these oils, the hydrocarbon componentthins the oil and keeps it moving around the loop. More complicatedpiping arrangements or large hold-up volumes may require thecomponent of POE.

R-422D: A retrofit blend that is designed to match R-22 in refrigerationapplications. There is a reduction in capacity which would result inlonger run times. There may also be excessive pressure drop in longpiping runs which may limit capacity further. The hydrocarboncomponent in R-422D helps promote oil return in systems containingmineral oil or alkylbenzene. Although HFC refrigerants won't mix withthese oils, the hydrocarbon component thins the oil and keeps itmoving around the loop. More complicated piping arrangements orlarge hold-up volumes may require the component of POE.

R-402A: This blend is formulated to match R-502 in medium to lowtemperature ranges and does not significantly increase dischargetemperature in R-502 retrofit situations. Discharge pressure, however,can increase from 25 to 40 psi over pressures seen with R-502.Although propane was included to improve oil circulation it is stillrecommended that some mineral oil be removed and replaced withalkylbenzene or POE.

R-402B: Similar components to R-402A but contains more R-22 andless R-125. This lowers the discharge pressure closer to R-502,however the discharge temperature increases compared to R-502. Thisis a benefit in ice machines, where the blend is primarily used,because it improves harvest times. Although propane was included toimprove oil circulation it is still recommended that some mineral oil beremoved and replaced with alkylbenzene or POE.

R-408A: A retrofit blend for R-502 refrigeration systems. This blendhas the closest pressure/temperature match to R-502 across the wholeoperating range of temperatures. Discharge temperature willincrease; however in most applications this will not impact systemperformance or long term reliability. In severe duty applications, suchas transport refrigeration into hot climates, this blend may not berecommended by the OEM.

AZEOTROPE: a mixture of two or more refrigerants in which the liquidand vapor have same composition at equilibrium. In addition, theresulting pressure of the mixture is either higher or lower than thepressure of any of the components. Azeotropes behave like purecomponent refrigerants because there is no change in boilingtemperature or shift in composition during phase change, equipmentoperation, or leakage.

R-500: Designed to be a higher capacity R-12 type refrigerant, R-500found some use in air conditioning and dehumidifier equipment and inpositive pressure centrifugal chillers.

R-502: Before its phaseout in 1995, it was used in low temperaturerefrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offered lower discharge temperature and improvedcapacity compared to R-22. Commercial refrigeration systems couldperform low temperature refrigeration in a single stage with relativelyinexpensive compressors.

R-13: Very low temperature refrigeration systems typically operate intwo or more stages (cascade type systems). It would be nearlyimpossible to achieve low temperatures in a single stage with aninexpensive compressor. Older cascade systems had a lowtemperature stage which used a lower boiling point gas, such as R-13or R-503, and a high stage which typically used R-12, R-22, or R-502.Hydrocarbons are often added to very low temperature systems tomake sure the oil stays fluid and returns from the very cold evaporator.R-13 can be replaced by R-23 or R-508B.

R-503: Very low temperature refrigeration systems typically operate intwo or more stages (cascade type systems). It would be nearlyimpossible to achieve low temperatures in a single stage with aninexpensive compressor. Older cascade systems had a lowtemperature stage which used a lower boiling point gas, such as R-13or R-503, and a high stage which traditionally used R-12, R-22, or R-502.

R-23: Used in very low temperature refrigeration systems, typically onthe low stage of a multi-stage system. Has properties similar to R-13and can be used to replace R-13 in an existing system. R-23 has higherdischarge temperatures than R-13, however, and equipment which isnot designed to take this into account may suffer related failures.Polyolester (POE) lubricants should be used, and it may still benecessary to charge hydrocarbon oil additives to ensure proper oilreturn. Check with OEM for specific oil and charging recommendations.

R-508B: Used in very-low-temperature refrigeration systems, typicallythe low stage of a multi-stage system. R-508B has properties similar toR-503 and can be used to replace either R-13 or R-503 in an existingsystem. The discharge temperature does not increase significantlycompared to R-23. POE lubricants should be used, and it may still benecessary to charge hydrocarbon oil additives to ensure proper oilreturn. Check with OEM for specific oil and charging recommendations.

R-403B: Used to replace R-13B1 in single stage, lower evaporatortemperature systems. With properties more similar to R-502 than R-13B1, the evaporator will operate in a vacuum when the low sidetemperature drops below -55°F. Existing R-13B1 systems that areretrofitted to R-403B will need the capillary tube replaced with alonger/more restrictive size. Similar lubricants can be used for R-403B,with any additives the manufacturer may recommend.

VERY LOW TEMPERATURE ALTERNATIVES

The low stage of a cascade system typically operates below -80°F. Atthese temperatures, standard refrigeration oils may begin to gum-upand lose their ability to flow around the sytem. Systems that run shortperiods of time, or cycle through warmer temperatures, may be able tokeep the oil returning to the compressor; however, systems that runlonger stretches of time at cold temperatures need to add

hydrocarbons to thin the oil and provide consistent oil return. In somecases, the hydrocarbons are used as the low stage refrigerant.National provides a variety of hydrocarbons in small quantities to beused for addition to very low temperature systems. Larger quantitiescan be specially ordered.

EZ ONE-SHOT™

Why is the EZ ONE-SHOT™ RecoveryCylinder different from traditionalrecovery cylinders?EZ ONE-SHOT™ cylinders use DOT-39disposable cylinder technology to

provide an inexpensive, lightweight cylinder for use in one-time fillrecovery situations.One-time fill means that once refrigerant has been put into thecylinder and then removed, the cylinder may no longer be used forfurther recovery operations. It must be scrapped or disposed ofproperly.Recovering refrigerant with an EZ ONE-SHOT™ recovery cylinder isconsidered the first filling operation. Recovery from several units, oneafter the other, until the cylinder is full represents one filling operation(for example, a dedicated shop machine).EZ ONE-SHOT™ recovery cylinders are subject to the same regulationsas the “disposable” refrigerant cylinder refrigerant is supplied in.Federal law forbids transportation if REFILLED. Federal law alsorequires that cylinders be filled and transported in the box provided.Penalty up to $500,000 fine and 5 years imprisonment (49 U.S.C. 5124).Applications for the EZ ONE-SHOT™• Temporary storage receiver (where policy demands a clean cylinder

for each job)• Single recovery job where gas will need to be returned or stored.• Dedicated shop machines.• Download everyday cylinder to return refrigerant.There are many situations in which you will still need your traditionalrecovery cylinders. The EZ ONE-SHOT™ cylinder will complement,butnot replace, your current recovery cylinder program.Applications where EZ ONE-SHOT™ should NOT be used:• Multiple small jobs at different locations or at different times —

back flow prevention valves will not allow additional recovery afterthe valves have been closed.

• “Everyday” service (can’t be filled more than once).

Carries the load between moving surfaces. The oil must separate the two moving surfaces so they do not comeinto contact, which results in excessive wear. The higher the viscosity of the oil, the more load the oil can carrybetween the two surfaces. If the compressor surfaces transfer more load than the oil can carry, the two movingsurfaces will come into contact with each other and may stick, weld together, or grind away at each other.

Friction reduction between two moving surfaces. The oil must help the two moving surfaces slide easily acrosseach other when under normal loads. Even at normal loads there may be some slight contact between the highpoints of each surface. The ‘slipperiness’ of the oil reduces the amount of friction between the two moving surfaces.

Cooling of internal compressor parts. The oil carries heat generated by internal friction and the compressionprocess away from the compressor. Since the oil is in such close contact with the internal components of thecompressor, it easily absorbs the heat generated there. As the oil flows back into the compressor sump, it cantransfer that absorbed heat outside the compressor. Some systems have an oil cooler to transfer large amounts ofheat, while others rely on transferring the heat through air moving over the compressor shell.

Prevents corrosion. The oil coats the metal surfaces and can prevent oxygen from attacking the metal surfaces.If the oil completely drains away from the surface during a prolonged off period, it may no longer protect thesurfaces. Very low viscosity oils will not provide as much corrosion protection as thicker oils.

Noise reduction. The oil helps make the compressor run much quieter by helping cushion metal surfaces that arecontacting each other. The oil helps prevent surfaces, like valves closing against their seats, from slamming intoeach other. The film of oil acts like a shock absorber to slow down the speed of the initial surface just before itmakes contact with the other surface.

Holds contaminants from the system. The oil acts as the holding area for many of the contaminants in thesystem. Acidity, particles, moisture and oil breakdown products are concentrated in the oil sump in many systems.This is normally why changing the oil is a good practice when the system is contaminated. The fresh oil will alsocollect the contaminants from the rest of the system after it is restarted, which is why multiple oil changes workwell to clean up badly contaminated systems.

POLYVINYLETHER OIL

PVE or polyvinylether lubricants arefinding increased application and useby compressor and equipmentmanufacturers. The list of OEM’s thathave tested and approved Idemitsu’sPVE Lubricants is impressive. PVE

lubricants exhibit excellent performance characteristics in airconditioning and refrigeration applications, and they are particularlywell suited for use with HFC refrigerants such as R-134a, R-404, R-407C, and R-410A. In fact, PVE lubricants are compatible with all HFCrefrigerants.In addition to its solubility and miscibily characteristics, the PVElubricant provides for increased stability and lubrication. In particular,PVE lubricants do not hydrolyze in the presence of moisture, a veryimportant feature in HVAC/R applications. Additionally, they arecompatible with other refrigeration oils and process fluids. PVElubricants also exhibit compatibility and performance with frequentlyused anti-wear additives.

WD40

Known as "the can with a thousanduses," WD-40 protects metal from rustand corrosion, penetrates stuck parts,displaces moisture, and lubricates justabout anything. WD-40 is also greatwhen it comes to cleaning grease,

grime, and other marks from most surfaces.• Gets under dirt, grime and grease to clean. It also dissolves

adhesives, allowing easy removal of labels, tape, stickers, andexcess bonding material.

• Because WD-40 displaces moisture, it quickly dries out electricalsystems to eliminate moisture-induced short circuits.

• Loosens rust-to-metal bonds and frees stuck, frozen or rusted metalparts.

• Lubricating ingredients are widely dispersed and hold firmly to allmoving parts.

• Protects metal surfaces with corrosion-resistant ingredientsto shield against moisture and other corrosive elements.

AEROKROIL

The oil that creeps and loosens frozenmetal parts. Reduces the surface tensionso that this amazing solvent creeps intoopenings as small as one millionth of aninch. Dissolves gum, dried grease, andoil -- without attacking the metal.
