5、he AmericanSociety of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Consensus is defined by the American National StandardsInstitute (ANSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reached bydirectly and materially affec
6、ted interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity.Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.” Compliance with thisstandard is voluntary until and unless a lega
7、l jurisdiction makes compliance mandatory through legislation.ASHRAE obtains consensus through participation of its national and international members, associated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the S
8、tandard. The ProjectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all ProjectCommittees. The Ma

It is
20、merelyinformative and does not contain requirements necessaryfor conformance to the standard. It has not beenprocessed 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 materi
21、al are notoffered the right to appeal at ASHRAE or ANSI.)FOREWORDThis standard is a revision of ANSI/ASHRAE Standard128-2001, Method of Rating Unitary Spot Air Conditioners.The title has been changed in this edition of the standard toreflect the more common description of these products, “por-table
22、air conditioners.” The scope of the standard has alsobeen revised; instead of covering units of all sizes, it nowapplies only to units with a cooling capacity of 19,000 W(65,000 Btu/h) and greater. This change reflects the fact thatsmaller portable air conditioners are now covered by ANSI/AHAM Stand
23、ard PAC-1 of the Association of Home Appli-ance Manufactures, and a similar standard, Standard C370,has been issued by the Canadian Standards Association. Bothof these cover portable air conditioners with capacities up to19,000 W (65,000 Btu/h). Finally, this new edition of Stan-dard 128 adopts the
24、rating methodology of C370 (which theAHAM standard also uses) so that all portable air condition-ers can be rated in the same way.Note: This standard is adapted from Standard C370-09by the Canadian Standards Association, with appropriatemodifications due to the difference in scope. Much of the texta
25、nd all of the figures and tables are reproduced with thepermission of Canadian Standards Association from C370-09,Cooling Performance of Portable Air Conditioners, which iscopyrighted by CSA Standards, 5060 Spectrum Way, Missis-sauga ON, L4W5N6 Canada. While use of this material hasbeen authorized,
26、CSA shall not be responsible for the mannerin which the information is presented, nor for any interpreta-tions thereof.1. PURPOSEThe purpose of this standard is to establish a uniform setof requirements for rating the cooling capacity of portable airconditioners.2. SCOPE2.1 This standard applies to
27、portable air conditioners with arated cooling capacity of 19,000 W (65,000 Btu/h) and above,including those with heating capacity.2.2 The standard does not apply toa. the testing and rating of individual assemblies, such ascondensing units or direct expansion fan-coil units forseparate use;b. comput
28、er or data-processing-room air conditionerswithin the scope of ASHRAE Standard 1271; andc. room air conditioners within the scope of CAN/CSA-C368.12or AHAM RAC-1.33. TERMINOLOGYIn this standard, “shall” is used to express a requirement,i.e., a provision that the user is obliged to satisfy in order t
29、ocomply with the standard; “should” is used to express a recom-mendation or that which is advised but not required; and“may” is used to express an option or that which is permissiblewithin the limits of the standard. Notes accompanyingsections do not include requirements or alternative require-ments
30、; the purpose of a note accompanying a section is toseparate from the text explanatory or informative material.Notes to tables and figures are considered part of the table orfigure and may be written as requirements. Legends to equa-tions and figures are considered requirements.4. GENERAL REQUIREMEN

The pub-lished ratings shall reference t
39、he configuration type as definedin Section 8.5.6.2 The Cooling Capacity and Spot Cooling Capacityratings shall be expressed in watts (Btu/h) in accordance withthe tests defined in Section 6.3.
