17、ganization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activitie

18、s, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject deal

19、t with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined

20、 by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

21、 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they

22、are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and

23、 the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not respon

24、sible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical comm

25、ittees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publicati

26、ons. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of pate

27、nt rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a Technical Report when it has collected data of a different kind

28、 from that which is normally published as an International Standard, for example “state of the art“. IEC TR 63061, which is a Technical Report, has been prepared by subcommittee 59M: Performance of electrical household and similar cooling and freezing appliances, of IEC technical committee 59: Perfo

29、rmance of household and similar electrical appliances. The text of this Technical Report is based on the following documents: Enquiry draft Report on voting 59M/71/DTR 59M/79/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated i

30、n the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC TR 63061:2017 IEC 2017 The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in

31、the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates tha

IEC TR 63061:2017 IEC 2017 5 INTRODUCTION A recent international review of energy efficiency standards and energy labelling progra

33、ms around the world found that refrigerators and freezers were covered by programs in some 75 countries, which included some 185 separate program measures. The report 1found that household refrigerators and freezers were the most frequently covered products around the world in terms of programs to i

34、mprove energy efficiency. Despite being the most commonly covered products in energy efficiency programs, there are a range of different approaches used in different countries to define energy efficiency for refrigerators and freezers. Besides specifying methods of energy measurement, IEC 62552-3 de

35、fines a clear and accurate method for the measurement and determination of compartment volume of household refrigerators and freezers. It is hoped that this international test method will be adopted by all countries in their local energy efficiency programs. However, a uniform approach to volume mea

36、surement is not always sufficient for energy efficiency policies, as this fails to take into account the impact of compartments that operate at different temperatures. One of the most common approaches used to define the energy efficiency of refrigerators and freezers is the concept of adjusted volu

37、me. This approach was developed in the 1980s and essentially weights the volume of each compartment in proportion to the temperature difference between the compartment temperature and the ambient temperature outside of the appliance. This provides a method that takes into account, at least to some e

38、xtent, the effect of variations in the relative size of different temperature compartments between different models. While there is a range of other possible approaches that can be used, adjusted volume is one method that is widely used around the world. While the concept of adjusted volume is widel

39、y used and well accepted, it appears that there are some variations and differences in how this parameter is calculated and applied in different countries. This creates anomalies in how energy efficiency parameters are calculated between countries. While the exact approach used to define adjusted vo

40、lume is ultimately a matter for individual countries, it is hoped that this document will provide a clear explanation of the approach and will provide a sound basis for how this can be applied in different conditions, as dictated by local policies. The purpose of this document is therefore to encour

41、age alignment in national approaches to the definition and application of adjusted volume. IEC 62552-3 defines two ambient temperatures for energy consumption measurement. Many countries, especially those with more temperate climates, will want to use this additional data to more accurately reflect

42、the likely energy consumption of refrigeration appliances during normal use. This document assumes that the adjusted volume is calculated using the ambient air temperature expected during normal use of the refrigerating appliance. It is hoped that this will further encourage alignment of approaches

43、across countries. Ultimately, it is hoped that this document will foster dialogue and cooperation between countries and encourage the use of more uniform approaches to the calculation and application of adjusted volume, where this is used in energy efficiency policies and programs. This will further

44、 encourage trade, development of more uniform efficiency benchmarks and overall improvements in energy efficiency globally. _ 1 Energy Standards and Labelling Programs Throughout The World In 2013, see http:/www.iea-4e.org/publications or http:/www.iea-4e.org/document/343/energy-standards-labelling-
