Introduction

This report provides data summaries from the ARTI Refrigerant Database. Volumes 1 and 2present refrigerant profiles for single-compound refrigerants and refrigerant profiles, respec-tively. Volume 3 presents data summaries for compatibility and toxicity. They are part of a se-ries to provide a record of the database entries in printed form.

Purpose

The Refrigerant Database is an information system on alternative refrigerants, associated lu-bricants, and their use in air conditioning and refrigeration. It consolidates and facilitates accessto property, compatibility, environmental, safety, application, and other information. It providescorresponding information on older refrigerants, to assist manufacturers and those usingalternative refrigerants to make comparisons and determine differences. The underlyingpurpose is to accelerate phase out of chemical compounds of environmental concern.

Contents

The database identifies sources of specific information on R-22, R-23, R-32, R-41, R-116, R-123, R-124, R-125, R-134, R-134a, R-141b, R-142b, R-143a, R-152a, R-218, R-227ea, R-236fa, R-245ca, R-245fa, R-290 (propane), R-C318, R-717 (ammonia), R-718 (water), R-744(carbon dioxide), R-1270 (propylene), ethers, and others as well as azeotropic and zeotropicblends of these fluids. These blends include R-400, R-401A, R-401B, R-401C, R-402A, R-402B, R-403A, R-403B, R-404A, R-405A, R-406A, R-407A, R-407B, R-407C, R-407D, R-408A,R-409A, R-409B, R-410A, R-410B, R-411A, R-411B, R-412A, R-413A, R-414A, R-414B,R-415A, R-416A, R-500, R-501, R-502, R-503, R-504, R-505, R-506, R-507A, R-508A,R-508B, R-509A, and others for which information is available even though standard designa-tions may not have been assigned yet. It addresses lubricants including alkylbenzene, polyal-kylene glycol, polyolester, and other synthetics as well as mineral oils. It also referencesdocuments addressing compatibility of refrigerants and lubricants with metals, plastics, elas-tomers, motor insulation, and other materials used in refrigerant circuits.

The database provides bibliographic citations and abstracts for publications that may be usefulin research and design of air-conditioning and refrigeration equipment. The complete docu-

Page 1

ments are not included, though some may be added at a later date. Incomplete citations orabstracts are provided for some documents. They are included to accelerate availability of theinformation and will be completed or replaced in future updates.

Limitations

The Refrigerant Database is intended as a means to assist users in locating sources of infor-mation on alternative refrigerants. But, the database is:

• neither a comprehensive nor authoritative reference source,

• not a substitute for independent data collection by users,

• not a substitute for examination of the data, information on how they were arrived at,assumptions, and caveats in the cited documents, and

• not an endorsement of suitability or accuracy of the referenced publications.

The information in the database was obtained from published and unpublished sources, orcalculated from them, without verification. Some of the data may be imprecise or incorrect, asmanifested - in some cases - by inclusion of conflicting data based on disagreement amongidentified sources. Similarly, errors may have occurred in assembling and processing the da-tabase. Users are cautioned to check the data and associated limitations and caveats in thereferenced documents and other sources before use, particularly if such use might risk harm tolife or property. Newer or more complete data may be available from refrigerant suppliers orelsewhere.

Materials compatibility, properties, safety considerations, and other characteristics affectingsuitability or desirability may be influenced by a number of factors. Among them are specificapplication conditions, preparation such as drying before use, additives including fillers, impu-rities, catalytic interactions with other materials used, and changes in compounding betweenone source or batch and another. Similarly, new findings or corrections may supersede previ-ously published data. The database is an aid in locating data that may be pertinent; it is not andshould not be viewed as the source of data for research, design, analysis, or other purposes.

Database Form

The database is available in both computerized ("electronic") and report ("manual" or "listing")versions.

Computerized Version

The computerized version includes both data summaries and bibliographic citations organizedinto a number of segments ("files"). These segments can be searched individually or together,in any combination.

The computerized database provides 606 specially-prepared data summaries, including refrig-erant (single compound and blend) profiles, tabular compatibility summaries for plastics and

Distribution of the Refrigerant Database

a Data summaries, citations, and synopses may be printed with the computer-ized version.

b The Copper Development Association (CDA) sponsored supplement providesadditional citations and synopses, most of which address compatibility with oruse of copper in air-conditioning and refrigeration systems. The supplement isincluded and searchable with the computerized version, but published as aseparate report.

c Use of the search and retrieval software is subject to acceptance of the licenseagreement for it; both accompany the computerized version.

d Distribution is limited to documents in the public domain or for which authori-zation has been obtained. Others may be ordered from their publishers, whichare identified in the bibliographic citations.

elastomers, and toxicity reviews for refrigerants. The refrigerant profiles cover designations,common uses, chemical and trade names, other identifiers, molecular mass, critical properties(pressure, temperature, specific volume, and density at the critical point), physical and thermo-physical properties for selected conditions, safety classifications, toxicity and flammability data,exposure limits, atmospheric lifetime, ozone depletion potential, global warming potential,halogen global warming potential, commercialization, phaseout, and other data.

The computerized version also provides more than 6,100 citations. They are organized into aprimary file that includes recently added and key references, a supplement on copper in airconditioning and refrigeration, and an archival group covering historical and supersededdocuments.

The search and retrieval software provided with the computerized version enables very fastsearches for user-selected terms or combinations of terms. The search program offers severalautomated features to simplify use. They include optional prompting by search category, anautomated "thesaurus" of synonyms and related terms, chain searches to broaden or narrowprior searches, a "wildcard" capability to allow entry of word segments, and a configuration ca-pability to customize a number of options. The program also allows printing of selected portionsof the database. Printing the entire database would yield more than 8,000 pages, so a printedversion is available for those who prefer to use the database manually.

Report Version

A listing of the recent and key citations is provided in report form. The citations are groupedunder the primary or first subject addressed; they are not cross-referenced under other topics.The computerized version, therefore, is better suited to search for information by subject.

Citations and summaries from the supplement on copper in air conditioning and refrigerationare published separately. They also are arranged by subject.

Archival and historic citations are included in a third report. They are presented in reversechronological order, beginning with the most recent. These citations remain accessible throughthe computerized version.

Documents

The database also includes a collection of published and unpublished documents, copies ofwhich can be ordered individually. Approximately one third of the documents cited in the data-base are included in this collection. They include documents that are not protected by copyrightor proprietary restrictions. They also include documents for which the authors or copyrightowners granted permission for reproduction and distribution. Documents that are not dis-

tributed through the database can be obtained from their publishers, libraries, and othersources (please refer to the database User's Manual for suggestions).

Ordering Information

The computerized version of the database and the report version for recently added and keyreferences can be ordered along with a subscription for updates. The report versions of thecopper supplement, archival citations, and data summaries are available as separate docu-ments distributed through the database.

ARTI Refrigerant Database - Data Summaries

The parameter descriptions that follow summarize the information included in data summariesfor refrigerants, also referred to as refrigerant profiles. Each entry consists of the followingparts:

• a label to identify and/or explain the data,

• a data value, typically rounded to common representation or limits of precision, gen-erally expressed metric units or dimensionless form (metric units conform to the In-ternational System, SI, modified to use the Celsius scale for temperatures in place ofthe Kelvin scale),

• units of measure if applicable,

• converted data and units in the inch-pound (IP) system for data expressed in metricunits,

• qualifying information on the data such as the animal species, exposure duration, andfraction of responses for toxicity test results, exposure periods, or manufactureridentity where the source is a safety data sheet, and

• four-digit alphanumeric Refrigerant Database ("RDB") number (discussed below).

The specific data included for each single-compound refrigerant or blend depend upon avail-ability. Multiple values are cited for the same or related parameters in some cases, for examplewhen conflicting data were published by multiple credible sources. The purpose of the databaseis to assist users in locating data rather than to endorse or verify specific data or to resolveinconsistencies and conflicts. Older data generally are deleted for simplification when theoriginal source reports later results or when scientific consensus is reported, but that does notsuggest endorsement of the newer data. Please refer to the discussion of data limitations onpage 2. The data values shown are included to assist users, but the primary information foreach entry is the four alphanumeric digit "RDB" number in the right-most column, which indi-cates the document or other source from which the data were taken. Those sources may belocated by searching for the number prefixed by "RDB" (for example RDB9901) in the database.

Identifiers

The refrigerant number shown in the heading is the standard designation based on those as-signed by or recommended for addition to ANSI/ASHRAE Standard 34-1997, Designation andSafety Classification of Refrigerants, as well as pending addenda and common industry exten-sions thereto. These familiar designations are used almost universally, usually preceded by"R-", "R", the word "Refrigerant", composition-designating prefixes (for example "CFC-","HCFC-", "HFC-", or "HC-"), or manufacturer trade names. Nonstandard and pending designa-tions generally are flagged as such or identified in notes included with the common uses.

The chemical formula indicates the molecular makeup of the single-compound refrigerants,namely those consisting of a single chemical substance. The blend composition is substitutedfor refrigerant blends, namely those consisting of two or more chemicals that are mixed to ob-tain desired characteristics. The composition consists of two parts. The first identifies thecomponents, in order of increasing normal boiling points and separated by slashes. The secondpart, which is enclosed in parentheses, indicates the mass fractions (as percentages) of thosecomponents in the same order. The profiles also indicate alternative chemical names, thecommon and historic names, index numbers for common reference databases, empirical andstructural chemical formulae, and standard container colors. Among the identifiers shown arethe:

• standard designation following American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), Standard 34-1997 (Designation and Safety Clas-sification of Refrigerants) as well as addenda, pending addenda (flagged), and com-mon industry extensions to it (flagged),

• variants using the "R-", "R", "R ", composition-designating prefixes (for example"CFC-", "HCFC-", or "HFC-"),

• common fluorochemical number and variants,

• halon number for chemicals also used or considered as fire suppressants,

• chemical name following the International Union of Pure and Applied Chemistry(IUPAC) convention,

• chemical name following other common conventions,

• common names,

• structural formula following the IUPAC convention,

• structural formula following other common conventions,

• empirical formula following the Hill convention,

• other formulae including some flagged as "not recommended" to enable location bythem

• Chemical Abstracts Service (CAS) registry number,

• Beilstein registry number,

• European Inventory of Existing Chemical Substances (EINECS) number,

• Merck index (volume and number),

• National Institute of Occupational Safety and Health (NIOSH) Registry of Toxic Effectsof Chemical Substances (RTECS) index number,

• trade name(s),

• historical name(s),

• names used for rule making notices for proprietary refrigerants in U.S. EnvironmentalProtection Agency (EPA) Significant New Alternatives Program (SNAP) notices,

• standard container color name and Pantone number as assigned by Air-Conditioningand Refrigeration Institute (ARI) Guideline N (Assignment of Refrigeration ContainerColors),

• composition for blends

• both mass and mole formulations for blends, and

• standard mass formulation tolerances for blends with ASHRAE safety classifications.

In some cases, primarily for proprietary blends, additional identifying information is included inthe description of common uses.

Common Uses

The uses focus on application as refrigerants followed, if applicable, by terse indications ofother applications if known. Limiting considerations such as toxicity, flammability, reactivity, orenvironmental concerns are cited for some substances.

This section also includes notes on pending changes in standard designations and safetyclassifications.

Physical Properties

The refrigerant profiles indicate key physical, thermodynamic, and transport properties at rep-resentative conditions, including the normal boiling point, 20 °C (68 °F), 60 °C (140 °F), and thecritical point.

Page 9

The molecular mass is a calculated value based on the atomic weights recognized by Interna-tional Union of Pure and Applied Chemists (IUPAC). It indicates the mass in grams of a mole ofthe refrigerant or, for blends, the mass-weighted average of a mole of the mixture.

The normal boiling point (NBP) is the temperature at which liquid refrigerant will boil at standardatmospheric pressure, namely 101.325 kPa (14.6959 psia). The NBP and most dimensionalunits in the tables are shown in both metric (SI) and inch-pound units of measure. Both thebubble point (temperature at which a bubble first appears, hence the temperature at whichboiling begins, for a blend) and dew point typically are shown for blends.

The critical temperature (Tc) is the temperature at the critical point of the refrigerant. The Tc

values shown for blends are the mass weighted averages of the component Tcs unless actualvalues have been determined.

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

The NBP and critical properties suggest the application range for which an individual refrigerantmight be suitable. Those with extremely low NBP lend themselves to ultra-low temperaturerefrigeration, for example in cryogenic applications. Those with high NBPs generally are limitedto high-temperature applications, such as for use in chillers or high-temperature heat pumps.Both capacity and efficiency decline in a typical vapor-compression (reverse Rankine) cycle, theone most commonly used, when condensing temperatures approach the Tc. The Pc will exceedthe operating pressure, except in transcritical cycles, which are uncommon except for R-744(carbon dioxide).

Environmental Data

The atmospheric lifetime (τatm) is an indication of the average persistence of the refrigerant, ifreleased into the atmosphere, until it decomposes or reacts with other chemicals. The valuesshown are composite atmospheric lifetimes. Separate lifetimes also are shown if known for thetropospheric (lower atmosphere where we live), stratospheric (next layer where global depletionof ozone is a concern), and higher layers, since the atmospheric chemistry changes betweenlayers.

The ozone depletion potential (ODP) is a normalized indicator, based on a value of 1.000 forR-11, of the ability of refrigerants (and other chemicals) to destroy stratospheric ozone mole-cules. The data shown are the modeled values adopted by the international scientific assess-ment. The ODPs shown for blends are mass-weighted averages. The values shown typicallyare modeled ODP values, the most indicative of environmental impacts. Semi-empirical ODPand regulatory values adopted in the Montreal Protocol also are indicated for some refrigerants.

Page 10

The semi-empirical ODPs are calculated values that incorporate adjustments for observed at-mospheric measurements. The concept is conceptually more accurate, but it is difficult tomeasure the data needed for representative adjustments accurately.

The regulatory values generally are required for specific purposes, but may not be updated withnewer findings after adoption. The ODP values listed in the annexes to the Montreal Protocol,for example, have not been updated since 1987 for chlorofluorocarbons (CFCs) and 1992 forhydrochlorofluorocarbons (HCFCs). A note in the Protocol indicates that the values "areestimates based on existing knowledge and will be reviewed and revised periodically."

The global warming potential (GWP) is a similar indicator of the potency to warm the planet byaction as a greenhouse gas. The values shown are relative to carbon dioxide (CO2) for an in-tegration period of 100 yr. Both the ODP and GWP are calculated from the τatm, measuredchemical properties, and other atmospheric data. The GWPs shown for blends are mass-weighted averages.

The τatm, ODP, and GWP values indicated for blends were calculated for the nominal blendcompositions.

The database also indicates halocarbon global warming potential (HGWP) and photochemicalreactivity at ground level if known.

Safety Data

The safety section is subdivided into classifications, recommended exposure limits, acute(short-term, single exposure) and chronic (long-term, repeated exposure) toxicity data, flam-mability data, and detection (appearance and odor) information. The exposure limits are furtherseparated into short-term occupational, long-term occupational, and emergency exposures.Depending on the refrigerant, more than 100 parameters - some with differing values forspecies or exposure durations in toxicity tests - are reported. The following brief summaryaddresses only the chronic toxicity and flammability indices used to determine standard refrig-erant safety classifications.

The first value is an occupational exposure limit, namely the Threshold Limit Value - TimeWeighted Average (TLV-TWA) or a consistent measure. It is an indication of chronic (long-term,repeat exposure) toxicity of the refrigerant. Some of the consistent toxicity indices are theworkplace Environmental Exposure Level (WEEL) guides and the Permissible Exposure Limit(PEL). These measures indicate adopted limits for workplace exposures for trained personnelfor typical workdays and work weeks.

Page 11

The Lower Flammability Limit (LFL) is the lowest concentration at which the refrigerant will burnin air under prescribed test conditions. It is an indication of flammability. The absence of an LFLor even an indication of nonflammable does not assure that a substance will not burn orexacerbate an existing fire under some conditions, such as when mixed with other fuels (suchas lubricants) or at elevated pressures and temperatures.

The Heat of Combustion (HOC) is an indicator of how much energy the refrigerant will releasewhen it burns in air, assuming complete reaction to the most stable products in their vaporstate. Negative values indicate endothermic reactions (those that require heat to proceed) whilepositive values indicate exothermic reactions (those that liberate heat).

The ASHRAE Standard 34 safety group is an assigned classification that is based on the TLV-TWA (or consistent measure), LFL, and HOC. It comprises a letter (A or B) that indicates rela-tive toxicity followed by a number (1, 2, or 3) that indicates relative flammability. These classi-fications are widely used in mechanical and fire construction codes, to determine requirementsto promote safe use. Most of these code provisions are based on ASHRAE Standard 15, SafetyCode for Mechanical Refrigeration.

Production Data

The final section of the refrigerant profiles indicates initial commercialization if known and thelast year production is allowed in developed countries under the Montreal Protocol.
