8、s an adoption, with Canadian deviations, of the identically titled IS0 (International Organization for Standardization) Standard 13256-2:1998 (first edition, 1998-08-l 5). It is one of two Standards that establish performance testing and rating criteria for factory-made residential, commercial and i
9、ndustrial, electrically driven, mechanical compression type heat pumps. The other Standard in the series is IS0 13256-1, Water-source heat pumps - Testing and rating for performance - Part 7: Water-to-air and brine-to-air heat pumps, which has been adopted as CAN/CSA-C13256-l-01. These two standards
10、 together supersede CANKSA-C446-94, Performance of Ground Source Heut Pumps, and CANKSA-C655-M91, Performance Standard for lnternul Water-Loop Heat Pumps. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Internal Water Loop Heat Pumps under the jurisdiction of the CSA Tech
11、nical Committee on Heating, Ventilation, and Air Conditioning Equipment and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard

CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products
16、of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis fo
17、r acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for which certification is desired by producers, consumers, or other interests.

International Organization for Standardization Case postale 56 l CH-1211 Geneve 20 l Switzerland Internet isoiso.ch ii 0 IS0 IS0 13256-2:1998(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national
34、 standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internationa
35、l organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft international Standards adopted by the technical committee
36、s are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. This part of IS0 13256 was developed by IS0 Technical Committee TC 86, Refrigeration, Subcommittee SC 6, Testing and rating of air-condit
37、ioners and heat pumps. IS0 13256 consists of the following parts, under the general title Wafer- source heat pumps - Tesfing and rating for performance: - Part 7: Wafer-to-air and brine-to-air heat pumps - Part 2: Water-to-wafer and brine-to-wafer heat pumps Annexes A and B form an integral part of
38、this part of IS0 13256. Annexes C and D are for information only. . III IS0 13256-2:1998(E) IS0 Introduction This part of IS0 13256 covers heating and cooling systems which are generally referred to as “water-source heat pumps.” These systems generally include an indoor coil with air-moving means, a
39、 compressor, and a refrigerant-to-water or refrigerant-to-brine heat exchanger. A system may provide both heating and cooling, cooling-only, or heating-only functions. iv INTERNATIONAL STANDARD o ISO IS0 13256-2:1998(E) Water-source heat pumps - Testing and rating for performance - Part 2: Water-to-
40、water and brine-to-water heat pumps 1 Scope 1.1 This part of IS0 13256 establishes performance testing and rating criteria for factory-made residential, commercial and industrial, electrically driven, mechanical-compression type, water-to-water and brine-to-water heat pumps. The requirements for tes
41、ting and rating contained in this part of IS0 13256 are based on the use of matched assemblies. 1.2 Equipment designed for rating at one application under this part of IS0 13256 may not be suitable for rating at all applications covered in this part of IS0 13256. 1.3 This part of IS0 13256 does not
42、apply to the testing and rating of individual assemblies for separate use or to units having two or more indoor sections connected to a single outdoor section. It does not apply to heat pumps covered in IS0 5151, IS0 13253 or lSO13256-1. NOTE - For the purpose of the remaining clauses, the terms “eq
43、uipment” or “heat pump” may be used to mean “water-to- water heat pumps” or brine-to-water heat pumps”, and the term “liquid” refers to either “water” or “brine.” 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this par
44、t of IS0 13256. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of IS0 13256 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of
45、IEC and IS0 maintain registers of currently valid International Standards.
