6、tyof Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Consensus is defined by the American National Standards Institute (ANSI),of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reached by directly and materiallyaffected interest cate
7、gories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity. Consensus requiresthat all views and objections be considered, and that an effort be made toward their resolution.” Compliance with this standard is voluntary untiland unless a legal jurisdiction ma
8、kes 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 Standard. The Proj
9、ectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, all mustbe technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all Project Committees. The Manager of Standar
10、ds of ASHRAE should be contacted for:a. interpretation of the contents of this Standard,b. participation in the next review of the Standard,c. offering constructive criticism for improving the Standard,d. permission to reprint portions of the Standard.ARI SAFETY DISCLAIMERARI does not set safety sta

23、wide federation of national standards bodies (ISOmember bodies). The work of preparing International Stan-dards is normally carried out through ISO technical commit-tees. Each member body interested in a subject for which atechnical committee has been established has the right to berepresented on th
24、at committee. International organizations,governmental and non-governmental, in liaison with ISO, alsotake part in the work. ISO collaborates closely with the Inter-national Electrotechnical Commission (IEC) on all matters ofelectrotechnical standardization.Draft International Standards adopted by t
25、he technicalcommittees are circulated to the member bodies for voting.Publication as an International Standard requires approval byat least 75% of the member bodies casting a vote.This part of ISO 13256 was developed by ISO TechnicalCommittee TC 86, Refrigeration, Subcommittee SC 6, Testingand ratin
26、g of air-conditioners and heat pumps.ISO 13256 consists of the following parts, under the gen-eral title Water-source heat pumpsTesting and rating forperformance:Part 1: Water-to-air and brine-to-air heat pumpsPart 2: Water-to-water and brine-to-water heat pumpsAnnexes A, B, C, D, and E form an inte
27、gral part of thispart of ISO 13256. Annexes F, G, and H are for informationonly.IntroductionThis part of ISO 13256 covers heating and coolingsystems which are generally referred to as “water-source heatpumps.” These systems generally include an indoor coil withair-moving means, a compressor, and a r
28、efrigerant-to-water orrefrigerant-to-brine heat exchanger. A system may provideboth heating and cooling, cooling-only, or heating-only func-tions.1. Scope1.1 This part of ISO 13256 establishes performance testingand rating criteria for factory-made residential, commercialand industrial, electrically
29、-driven, mechanical-compressiontype, water-to-air and brine-to-air heat pumps. The require-ments for testing and rating contained in this part ofISO 13256 are based on the use of matched assemblies.1.2 Equipment designed for rating at one application underthis part of ISO 13256 may not be suitable a
30、t all applicationscovered in this part of ISO 13256.1.3 This part of ISO 13256 does not apply to the testing andrating of individual assemblies for separate use, nor to thetesting and rating of heat pumps covered in ISO 5151, ISO13253 or ISO 13256-2.NoteFor the purpose of the remaining clauses, the
31、terms“equipment” or “heat pumps” may be used to mean “water-to-air heat pumps” or “brine-to-air heat pumps” and the term“liquid” refers to either “water” or “brine.”2.
