21、processed according to the ANSI requirements for astandard and may contain material that has not beensubject to public review or a consensus process.Unresolved objectors on informative material are notoffered the right to appeal at ASHRAE or ANSI.)FOREWORDASHRAE Standard 182 is a method of test (MOT

22、) stan-dard for use in factory-performance testing of absorptionchillers/heaters. It was developed as a result of an agree-ment between ASHRAE and the Air Conditioning andRefrigeration Institute (ARI) (now the Air Conditioning,Heating and Refrigeration Institute AHRI), resulting inASHRAE ownership o

23、f MOT standards for use in conjunc-tion with ARI rating procedures. This standard is intendedfor use in conjunction with absorption chiller rating proce-dures such as ANSI/AHRI Standard 560, Absorption WaterChilling and Water Heating Packages.Absorption chillers are used for producing chilled waterf

24、rom a hot fluid. Natural gas or other combustible sub-stances can also be used as a heat source with direct-firedchillers. In the latter case, chillers may be designed to pro-vide a water-heating capability in addition to the water-chilling capability. There are three different modes that achiller c

25、ould potentially be operated in: cooling-only mode,heating-only mode, and simultaneous heating/cooling mode.This MOT can be applied to any of these test modes,although each mode should be considered as a separate anddistinct test. The most commonly prescribed test mode iscooling-only. Test facilitie

26、s that are designed for cooling-only operation may not be capable of performing heating-only or simultaneous heating/cooling tests. As a result, usersof this standard need to carefully consider facility capabili-ties when prescribing heating-only or simultaneous heating/cooling tests.This standard i

27、s targeted toward commercially availableproducts, including products employing single- and double-effect absorption cycles. Although lithium-bromide/waterchillers are the most common type, absorption chillers usingother fluids, such as ammonia/water, can be tested using thisstandard as well. Further

28、, this standard is intended for usewith water-cooled products and does not include provisionsfor the testing of air-cooled products.This is a reaffirmation of Standard 182-2008. This stan-dard was prepared under the auspices of ASHRAE. It may beused, in whole or in part, by an association or governm

29、entagency with due credit to ASHRAE. Adherence is strictly ona voluntary basis and merely in the interests of obtaininguniform standards throughout the industry.The changes made for the 2013 reaffirmation wereChanged “ARI” to “AHRI”Moved Informative Example art to Informative Appen-dix B1. PURPOSETh

30、e purpose of this standard is to prescribe a method oftesting absorption water-chilling and water-heating packagesto verify capacity and thermal energy input requirements at aspecific set of operating conditions.2. SCOPEThis standard applies toa. absorption packages used to chill and/or heat water,

31、asdefined in Section 3, Definitions, andb. testing that will occur where proper instrumentation andload stability can be provided.c. It is not the intent of this standard to provide for testingin typical field installations, where steady-state condi-tions are often difficult to achieve and adequate

32、provi-sions for measurement are not made.3. DEFINITIONSThefollowingkeytermsaredefinedinthissection.Forallother terms, refer to ASHRAE Terminology of Heating, Venti-lation, Air Conditioning, and Refrigeration.1absorption package: a factory-designed and pre-fabricatedassembly used for chilling and/or

33、heating water that consistsof an evaporator, absorber, condenser, generator(s), and solu-tion heat exchanger(s), with interconnections and accessories.Thepackageutilizesamixtureofatleasttwocomponents.Themore volatile component is the refrigerant, and the less vola-tile mixture with high affinity to

34、the refrigerant is the absor-bent solution. Either single or multiple reconcentrations of anabsorbent solution, known as effects, can be used. A single-effect package employs a one-step reconcentration of theabsorbent in the generator. Refrigerant vapor is released whenthermal energy is introduced i

35、nto the generator. The concen-tratedabsorbentisreturnedtotheabsorberwhereitcanabsorbrefrigerant vapor flashed off in the evaporator, and the cyclerepeats. A double-effect package employs a two-step recon-centration of the absorbent through the use of an additionalhigh-temperature generator.Absorptio
