13、w Zealand Committee EL-015, Quality and Performance of Household Electrical Appliances to supersede AS/NZS 4474.2:2001 on publication. The AS/NZS 4474 series comprises two Parts, as follows: AS/NZS 4474 Performance of household electrical appliancesRefrigerating appliances 4474.1 Part 1: Energy cons
14、umption and performance 4474.2 Part 2: Energy labelling and minimum energy performance standard requirements (this Standard) The overall objective of this series of Standards is to promote high levels of quality, performance and energy efficiency in refrigerating appliances. The Parts of AS/NZS 4474
15、 are summarized as follows: (a) Part 1 includes performance test procedures and minimum performance criteria for refrigerating appliances. (b) Part 2 includes algorithms for the calculation of the energy efficiency star rating and projected energy usage, performance requirements (including MEPS), de
16、tails of the energy label and requirements for the valid application thereof. It has been structured to be suitable for reference in regulatory legislation and to be used in conjunction with Part 1. This revision is to allow for the introduction of a new energy labelling algorithm and new energy lab
17、el design. The new energy labelling algorithms and label design were developed and agreed on by industry and government representatives during 2007/2008 and were canvassed widely in various discussion papers, a costbenefit analysis and a regulatory impact statement. The new energy label includes a l
18、abel variant which awards additional stars for very efficient products where they rate 7 or more stars under the new algorithm. This revision also mandates the use of AS/NZS 4474.1:2007 for test reports and energy labelling and MEPS registrations for registrations to this Standard. New Zealand has r
19、equired the use of this Standard for new registrations and re-registrations since April 2008. The use of AS/NZS 4474.1:2007 is critical as it contains new rules for temperature sensor placements in some cases, differences in calculation of compartment temperature for frost free products and a number
20、 of anti-circumvention measures. For some refrigerating appliances, it may be possible to reissue a test report to the new Standard without the need for retesting if the original source data is still available and other settings and rules remain compatible. Another important change in this Standard
21、is a small adjustment to the MEPS levels to take account of the expected changes to the tested energy consumption when using AS/NZS 4474.1:2007. This occurs because the temperature determination period now includes the defrost and recovery period. The adjustment is 1% or less and only applies to Gro
22、ups 5T, 5B, 5S and 7. The technical details are contained in a discussion paper released by the Equipment Energy Efficiency (E3, which is made up of officials from State and Federal governments in Australia and New Zealand) in October 2007 and is available from www.energyrating.gov.au in the electro
23、nic library. The Standard is downloaded from Standard Sharing 3 AS/NZS 4474.2:2009 This Standard also changes the definition of MEPS for all products within its scope from a value based on the average PAEC (as defined in AS/NZS 4474.2:2001 and previous editions) to a maximum permitted energy for an
24、y individual unit of a model. The Kf, Kv and feature allowances for MEPS have all been adjusted to reflect this change in MEPS definition. While the new MEPS levels are adjusted to be equivalent to the previously published 2005 levels, it is necessary to re-register all products to the newly defined
25、 levels when making an application for the new energy label as there may be small variations at a model level. This change of MEPS definition (called MEPS 2010 in this Standard) also means that there is a change in the verification procedure for MEPS for refrigerators and freezers which are register
26、ed to this Standard. These procedures are included in the E3 Administrative Guidelines. From April 2009, it is anticipated that regulatory authorities will begin accepting applications to register for AS/NZS 4474.2:2009. In Australia, all appliances within the scope of this Standard, manufactured or
27、 imported for sale in Australia on or after 1 April 2010, are required to be registered to this Standard. In New Zealand, this Standard is expected to be incorporated by reference into New Zealand law prior to 1 April 2010 to align with the Australian regulatory processes. Once incorporated all item
28、s that are within the scope of AS/NZS 4474.2:2009, that are manufactured in, or imported into New Zealand may not be sold to a consumer unless they comply with this Standard. An overview of the regulatory requirements in New Zealand for energy labelling and MEPS is included in Appendix F. Administra
29、tive arrangements during the transition period may vary so registration holders should contact their regulator to obtain detailed requirements with respect to labelling and registration requirements (see also Section 4 and Appendix F of this Standard). This Standard is published with the approval of
30、 the combined state regulatory authorities and is structured to be suitable for reference in energy labelling regulatory legislation. It refers to Part 1 for test procedures. Check testing, where applicable, will be undertaken to the version of the test Standard or the appropriate MEPS levels which
31、have been used to support the current energy label for that model. A summary of the Administrative Guidelines has been included in Appendix F for the information of users of this Standard. From 2009 it is anticipated that Fiji and other South Pacific Island nations may use the Australian/New Zealand
32、 energy labelling and MEPS system within their own jurisdictions on a cooperative basis. The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative a
33、ppendix is only for information and guidance.

39、9 6 FOREWORD The desire of governments to improve the energy efficiency of appliances has led to the development of Minimum Energy Performance Standards (MEPS) and the associated energy labelling scheme. The first MEPS levels (MEPS 1999) for refrigerators and freezers were implemented on 1 October 1
40、999 and revised MEPS levels (MEPS 2005) became applicable on 1 January 2005 (refer also to Clause 1.1). In this edition, the MEPS definition, which was previously based on a model average energy value, is altered to become a maximum energy value for any unit within a model (republished as MEPS 2010)
41、 in this Standard. MEPS 2010 levels are intended to be technically equivalent to MEPS 2005. In this Standard, MEPS have allowances for special features such as extra doors and through-the-door water/ice dispensers which are excluded from the star rating calculations and associated labelling requirem
42、ents. The original energy labelling algorithm was introduced in 1986 and this was revised from a linear progression (fixed energy reduction per additional star) to a geometric progression in 2000 (fixed percentage reduction per addition star) and was implemented in conjunction with a new label desig
43、n and format. The function for calculating the star rating of an appliance group in 2000 was broadly set at a one star rating generally coinciding with the 1999 MEPS requirements for groups that performed similar energy service. The 2010 algorithm introduced in this edition is a new approach which d
44、etermines the Base Energy Consumption (BEC) using a volume function to the power of 0.67 to better reflect the surface area change (which is a key driver for energy consumption) as volume changes. The same geometric progression previously used has been retained but the energy reduction factor has be
45、en set to 0.23 (23% energy reduction per star) for all groups. Some refined label design elements have been included in this Standard and a new label variant has also been introduced to award products that achieve at least 7 stars under the new energy labelling algorithm. This will also extend the l
46、ife of the algorithm and will allow a longer period between future energy label algorithm regrades.
