    ozone layer forced scheduledphaseouts of ozone-depletingrefrigerants, among them chlo-rofluorocarbons (CFCs), suchas R-12, andin the futurealso hydrochlorofluorocarbons(HCFCs), such as R-22. Themeasures also addressed similar

    chemicals for other applications, such as manywidely used aerosol propellants, foam blowingagents, fire suppression agents (notably halons), and

  • a more significantor at least muchmore challengingenvironmental issuenow heralds a looming fourth generationto address global warming. This term is abit misleading, as the impacts of climatechange include warming in most regionsbut cooling in some (for example, inparts of Europe). It also includes sea levelrise and attendant coastal land loss,changes in growing seasons and soilmoisture retention (and, therefore, cropyields), and spread of diseases such asmalaria now nearly localized to equato-rial regions. In short, global climatechange may impact virtually all aspects oflife and raises significant internationaland intergenerational equity issues.

    Interestingly, some of the fluids con-sidered natural refrigerants (primarilyammonia, carbon dioxide, hydrocar-bons, and water) in the first generationare being re-examined to replace syn-thetic refrigerants (primarily fluoro-chemicals) because of environmentalconcerns. Many of the claims and coun-terclaims for such fluids are more emo-tional or marketing-based than technical.

    Most of the safety, durability, and per-formance issues that drove early refriger-ant shifts remain concerns today, compli-cated by focus on low ozone depletionpotential (ODP), low global warmingpotential (GWP), short atmospheric life-time (atm), and, perhaps most impor-tantly, high efficiency. There are linkagesthat force trade-offs among these criteria,but none of them can be ignored.1

    Manufacturers have commercializedmore than 30 new refrigerants in the pastdecade, and they are examining addi-tional candidates. Most new refrigerantsare blends, because the options for suit-able single-compound refrigerants aremuch more limited and generally alreadyexploited. Users should expect a numberof additional introductions as the phase-out approaches for R-22, now the mostwidely used refrigerant. A similar flurryof service fluid introductions occurredwith the earlier phaseout of R-12 (then,the most widely used refrigerant) and R-502. Data refinement continues for both

    existing and new refrigerants with im-provements in measurement methods,further studies, and new understanding,especially of environmental impacts.

    REFRIGERANT DATA TABLESThis article provides two tables that

    update2,3,4 and expand selected physical,safety, and environmental data for com-mon refrigerants (retired and current)and leading candidates. The two tablescontain the same data sorted differently.Table 1 is arranged by standard refriger-ant designations, while Table 2 is sortedby refrigerant boiling points. Table 1lends itself to finding information on aspecific refrigerant. The sort order forTable 2 rearranges the refrigerants incoarse proximity of candidacy for similarapplications, to facilitate comparisons.

    The parameter descriptions that fol-low are in the same sequence as presentedin Tables 1 and 2, going from the left tothe right columns.

    IdentifiersThe number shown is the standard

    designation based on those assigned byor recommended for addition toANSI/ASHRAE Standard 34-2004,Designation and Safety Classification ofRefrigerants,5 and addenda thereto for an-ticipated consistency with 34-2007when published. These familiar designa-tions are used almost universally, usuallypreceded by R-, R, the word Refrigerant,composition-designating prefixes (for ex-ample CFC, HCFC, HFC, or HC), ormanufacturer trade names.

    The chemical formula indicates themolecular makeup of the single-com-pound refrigerants, namely those consist-ing of only one chemical substance. Theblend composition is shown for refrigerantblends, namely those consisting of two ormore chemicals that are mixed to obtaindesired characteristics. The compositionconsists of two parts. The first identifiesthe components, in order of increasingnormal boiling points and separated byslashes. The second part, enclosed in pa-rentheses, indicates the mass fractions (aspercentages) of those components in the

    same order. The tables also indicate com-mon names by which some refrigerantsare frequently identified.

    Physical propertiesThe molecular mass is a calculated

    value based on the atomic weights recog-nized by International Union of Pure andApplied Chemists (IUPAC).6 It indicatesthe mass in grams of a mole of the refrig-erant or, for blends, the mass-weightedaverage of a mole of the mixture.

    The normal boiling point (NBP) is thetemperature at which liquid refrigerantboils at standard atmospheric pressure,namely 101.325 kPa (14.6959 psia). TheNBP and most dimensional units in thetables are shown in both metric (SI) andinch-pound (IP) units of measure. Thetemperature of the sublimation point isshown for refrigerants that sublimate,such as R-744 (carbon dioxide). Thebubble point temperatureat which abubble first appears and boiling beginsis shown as the NBP for blends. Unlikesingle-compound refrigerants that boil ata single temperature for a given pressure,the dissimilar volatilities of componentscause mixture boiling to span a range be-tween the bubble point and dew pointtemperatures. The dew point is so namedbecause it is the condition at which con-densation begins when the blend iscooled.

    The critical temperature (Tc) is thetemperature at the critical point of the re-frigerant, namely where the properties ofthe liquid and vapor phases are identical.Unless actually determined, the Tc valuesshown for blends are the mass weightedaverages of the component Tcs, some-times referred to as the pseudo-criticaltemperature.

    The critical pressure (Pc) is the pressureat the critical point.

    The NBP and critical properties sug-gest the application range for which anindividual refrigerant might be suitable.Those with extremely low NBPs lendthemselves to ultralow temperature re-frigeration including cryogenic applica-tions. Those with high NBPs generallyare limited to high-temperature applica-

  • tions, such as chillers and industrial heatpumps. Both capacity and efficiency de-cline when condensing temperatures ap-proach the Tc in a typical vapor-compres-sion (reverse-Rankine) cycle, the onemost commonly used. Pc will exceed theoperating pressure except in transcriticalcycles, which are uncommon except forR-744 (carbon dioxide). It is useful tocompare relative operating pressures be-cause practical cycles usually are designedto condense at 70 to 90 percent of the Tc(on an absolute basis) and, therefore, atcorresponding fractions of the Pc.1,7

    Safety dataThe first safety column included in

    the tables tabulates the occupational expo-sure limit (OEL). It is an indication ofchronic (long-term, repeat exposure) tox-icity of the refrigerant for trained individ-uals likely to be exposed during theirwork. Common OELs include theAmerican Conference of GovernmentalIndustrial Hygienists (ACGIH) Thresh-old Limit Value-Time Weighted Average(TLV-TWA), the American IndustrialHygiene Association (AIHA) WorkplaceEnvironmental Exposure Level (WEEL)guide, the Deutsche Forschungsgemein-schaft (DFG) maximale ArbeitsplatzKonzentration (MAK, the maximumworkplace concentration), the Japan So-ciety of Occupational Health (JSOH)OEL, and the U.S. Occupational Safetyand Health Administration (OSHA)Permissible Exposure Limit (PEL). Somecountries and manufacturers refer tothem as the acceptable exposure limit(AEL), industrial exposure limit (IEL),workplace exposure standard, or withsimilar terms. These measures indicaterecommended or adopted limits forworkplace exposures for trained person-nel for typical workdays and work weeks.OELs normally are expressed in ppm byvolume (ppm v/v) on a time-weightedaverage (TWA) basis for a normal work-day and workweek, unless preceded by aC to designate a ceiling limit.

    The lower flammability limit (LFL) isthe lowest concentration at which the re-frigerant burns in air under prescribed

    test conditions. It is an indication offlammability.

    The heat of combustion (HOC) is anindicator of how much energy the refrig-erant releases when it burns in air, assum-ing complete reaction to the most stableproducts in their vapor state. Negativevalues indicate endothermic reactions(those that require heat to proceed),while positive values indicate exothermicreactions (those that liberate heat).

    The ASHRAE Standard 34 safetygroup is an assigned classification that isbased on data used to determine theTLV-TWA (or consistent measure), LFL,and HOC. It comprises a letter (A or B)that indicates relative toxicity followed bya number (1, 2, or 3) that indicates rela-tive flammability. These classificationsare widely used in mechanical and fireconstruction codes to determine require-ments to promote safe use. Most of thesecode provisions are based on ASHRAEStandard 15, Safety Standard for Refriger-ation Systems. Some of the classificationsshown are followed by the lower case let-ter r. It signifies that the committee re-sponsible for ASHRAE 34 has recom-mended revision or addition of theclassification shown, but final approvaland/or publication is still pending. Simi-larly, a d indicates a deletion.

    Blends were assigned dual classifica-tions, such as A1/A2, in the past to indi-cate the safety groups both as formulatedand for the worst case of fractionation.That practice changed to assignment of asingle safety group reflecting the worstcase of fractionation for specified leakand refill scenarios.

    Environmental dataThe atmospheric lifetime (atm) is an in-

    dication of the average persistence of re-frigerant released into the atmosphereuntil it decomposes, reacts with otherchemicals, or is otherwise removed.While atm factors into additional envi-ronmental parameters, it also is signifi-cant in its own right. It suggests the po-tential for atmospheric accumulation ofreleased refrigerants (and other chemi-cals). Long atmospheric lifetime implies

    the potential for slow recovery from envi-ronmental problems, both those alreadyknown and additional concerns identi-fied in the future.

    The values shown for the refrigerantlives are composite atmospheric life-times. The lifetimes also can be shownseparately for the tropospheric (lower at-mosphere, where we live), stratospheric(next layer, where global depletion ofozone is a concern), and higher layers be-cause the dominant atmospheric chem-istry changes between layers.

    The ozone depletion potential (ODP) isa normalized indicator, based on a valueof one for R-11, of the ability of refriger-ants (and other chemicals) to destroystratospheric ozone molecules.

    The values shown in Tables 1 and 2 aresemi-empirical ODPs, calculated valuesthat incorporate adjustments for ob-served atmospheric measurements.8 TheODPs shown for blends are mass-weighted averages. The semi-empiricalapproach is conceptually more accuratethan other measures, though it is stillevolving with further and improvedmeasurements and understanding.

    Previous summaries2,3,4 focused onmodeled ODP values, then deemed themost indicative of environmental im-pacts based on consensus internationalassessments. There are several otherODP indices, including time-dependentand regulatory variations.

    Time-dependent ODPs use chemicalsother than R-11 as the reference. Nor-malizing values to short-lived com-pounds emphasizes near-term impacts,but discounts long-term effects. Time-dependent ODPs are not cited often, be-cause release of ozone-depleting sub-stances already has peaked, and recoveryof the stratospheric ozone layer is underway.

    The global warming potential (GWP)is a normalized indicator of the potencyto warm the planet by action as a green-house gas. The values shown are relativeto carbon dioxide (CO2) for an integra-tion period of 100 years, again based on
