2、2005 edition of AS/NZS 3823.2 is amended as follows; the amendment(s) should be inserted in the appropriate place(s). SUMMARY: This Amendment applies to the Preface, Clauses 1.1, 1.2, 2.3.3, 2.10, 3.2, 3.4, 3.8, 4.1.2, 4.1.3, 4.1.4, 4.1.5, 4.1.6, 4.2.2, 4.2.3, 5.4, Appendices B, D and F and Table 3.
3、1. Published on 29 February 2008. Approved for publication in New Zealand on behalf of the Standards Council of New Zealand on 22 February 2008. PREFACE 1Last paragraph, Page 2, delete the first sentence. 2Delete Item (f) on Page 3 and replace with the following: (f) More stringent single-phase MEPS
4、 levels for some categories of products were introduced on 1 April 2006 while MEPS levels for remaining single-phase products became more stringent on 1 October 2007. 3Page 3, after the third last paragraph beginning Section 4 of this Standard, add the following: Amendment No. 3 to this Standard del
5、etes single-phase MEPS requirements for all products from 2008 which were included in the 2005 revision of this Standard. These levels will be reviewed and a new implementation date proposed following the release of new Regulatory Impact Statement (RIS) due in late 2007. This will be confirmed once
6、it has been approved by the Ministerial Council for Energy. Amendment No. 3 introduces more stringent requirements for variable output airconditioners where these products do not meet MEPS at rated output. There are also additional reporting requirements for variable output products. Amendment No. 3
7、 requires a specific written approval from regulators where a supplier is seeking an exemption from energy labelling for commercial non-ducted single-phase airconditioners. Amendment No. 3 also provides an updated indicative timing of the likely transition to a new energy label algorithm in 2009. Cl

AMDT No. 3 FEB 2008 AMDT No. 3 FEB 2008 Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 22 Apr 2008 Clause 1.2 Add new Item (h) as follows: (h) Models may be granted exemption from
9、the requirement to carry an energy label by the relevant Australian/New Zealand regulatory authority due to their specific design for commercial applications. In these cases, the supplier will be required to make an application for each model where an exemption is sought and provide documentation to
10、 satisfy regulators that an exemption from mandatory energy labelling is warranted because the product is (i)designed for and used only in non-residential applications; and/or (ii)not on display for sale through retail outlets; and/or (iii)not promoted in any catalogue or advertising material that c
11、ould be interpreted as suitable for some residential applications. Clause 2.3.3 Add the following new paragraph after Item (b): The unit shall be operated at rated capacity under the cooling capacity test with CONDITION T1 in accordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3 for
12、the determination of cooling capacity, effective power input, energy efficiency ratio and compliance with minimum EER cooling requirements. Clause 2.10 Delete this Clause. Clause 3.2 Add new Note after first paragraph, as follows: NOTE: An analysis of the impacts of MEPS levels for single- and three
13、-phase airconditioners is being conducted during 2007 and a cost benefit analysis is also expected in 2007. This will propose a revised implementation date for the levels that are scheduled for October 2008 (deleted from this amendment) as well as revised MEPS levels for some other product types. An
14、nouncements of MEPS for close control and multi-split systems are expected in the near future.

16、ONDITION T1 in AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3, are deemed to comply with MEPS if they meet both of the following requirements: (a)The tested EER at rated capacity is not less than 95% of specified MEPS level. (b)The tested EER of a part load point selected by the supplier and
17、documented with a test report supplied with the registration demonstrates that the model meets or exceeds either one of the following two requirements: (i)For an output in the range 83.3% to 100% of rated capacity, the tested EER meets or exceeds the MEPS level. (ii)For an output in the range 50% to
18、 83.3% of rated capacity, the tested EER meets or exceeds the following equation: MEPS Output Output EER 3 . 025. 1 capacityrate loadpart tested NOTE: Australian and New Zealand regulators intend to carefully review and possibly remove the part load MEPS compliance option for variable output product
19、s as part of the next MEPS level (nominally October 2009). Clause 3.8 Add the following new paragraph after the Note: While it will remain a requirement to supply to regulators any information on how to lock the speed of variable output systems during testing as part of the registration process, man
20、ufacturers should make such information readily available to facilitate third party testing. Wherever possible, manufacturers should design their products in a way that the capacity of variable output systems can be locked for testing purposes using controls on the product or using equipment normall
21、y supplied with the product (i.e., without the need for special test equipment supplied by the manufacturer). Clauses 4.1.2 to 4.1.6 Delete Clauses 4.1.2 to 4.1.6 and replace with the following: 4.1.2 Registration For an energy labelling and/or MEPS application in accordance with Appendix B, a test

For a MEPS application in accordance with Appendix B, a test report to AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3, or a summary
23、 report in accordance with Appendix C shall be provided where physical tests have been conducted for the relevant test points. Where a simulation to AS/NZS 3823.3 has been conducted for a MEPS application in accordance with Appendix B, a report in accordance with Appendices A and B of AS/NZS 3823.3
24、shall be provided. AMDT No. 3 FEB 2008 AMDT No. 3 FEB 2008 AMDT No. 3 FEB 2008 Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 22 Apr 2008 Where a supplier wishes to indicate the heating capacity on the energy label at 2C in accordance with Section 5, this shall be indicated in the energy labelling app
25、lication in Appendix B. To support the claimed heating capacity output and to verify the performance requirements in Clause 3.9, a test report to AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or a summary report in accordance with Appendix C of this Standard shall be provided for Condition H2. NOTES: 1Applicat
26、ions in the form of computer printouts, which present all the application data in a similar layout to the forms in Appendix B, are valid. 2Where HPRATE has been used for a simulation to support a MEPS application, a copy of the project (sys) file is regarded as equivalent to a report in accordance w
27、ith Appendices A and B of AS/NZS 3823.3:2002. Where values other than the defaults for pressure drop, subcooling or superheating are used in the project file (see Appendix A), test data to support the use of these values will be required. Simulations for heating may not be valid where defrosting cou

The documents required by this Section shall be made available to the relevant regulatory authority upon request. Records shall be retained for at least five years afte
30、r the last date of manufacture or import, whichever is applicable. 4.1.4 MEPS transition All products within the scope of MEPS manufactured or imported for sale in Australia on or after the relevant MEPS date shall meet the relevant MEPS requirements. Such units shall hold a valid registration at th
31、e time of sale, which shall indicate compliance with these MEPS requirements. Variable output products which have used the part load provisions of Clause 3.4 up to and including Amendment No. 1 of this Standard to claim MEPS compliance will expire on 31 March 2009. Only new registrations to Amendmen
32、t No. 3 of this Standard will be permitted from 1 February 2008. NOTE: More details on the duration and validity of registrations can be found in the Administrative Guidelines.

33、tors have advised that products with existing registrations for energy labelling to a previous edition of this Standard can continue to affix and display these previously approved labels until the product requires re-registration for MEPS or energy labelling as defined in this Standard. Products wit
34、h energy labels to previous editions of this Standard, which are manufactured or imported prior to the relevant regulatory date, may be supplied directly from a warehouse without the need to re-label for an indefinite period. NOTE: Energy labelling algorithms are due to change in 2009 (refer to Appe
35、ndix F) and are to be defined in a future edition of this Standard. Special provisions will apply to products on display in retailers during the 2009 energy transition period. Details of these provisions will be contained in a forthcoming revision of this Standard. Accessed by UNIVERSITY OF SOUTH AU
