AS/NZS 3823.2:2005 2 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL-15, Quality and Performance of Household Electrical Appliances, to supersede AS/NZS 3823.2:2003 (including Amendment 1). The AS/NZS 3823 se
15、ries comprises five Parts, as follows: AS/NZS 3823 Performance of electrical appliancesAirconditioners and heat pumps 3823.1.1 Part 1.1: Test methodsNon-ducted airconditioners and heat pumpsTesting and rating for performance 3823.1.2 Part 1.2: Test methodsDucted airconditioners and air-to-air heat p

17、ormance for minimum energy performance standard (MEPS) requirements The overall objective of the AS/NZS 3823 series of Standards is to promote high levels of performance and energy efficiency in airconditioners and heat pumps. The Parts of the AS/NZS 3823 series are summarized as follows: (a) Part 1
18、.1 includes performance test procedures for rating non-ducted airconditioners and heat pumps, to be used in conjunction with Part 2. (b) Part 1.2 includes performance test procedures for rating ducted airconditioners and heat pumps, to be used in conjunction with Part 2. (c) Part 1.3 includes perfor
19、mance test procedures for rating water-to-air heat pumps and airconditioners with water cooled condensers, to be used in conjunction with Part 2. (d) Part 2 specifies minimum energy performance standard (MEPS) requirements and includes algorithms for the calculation of the energy efficiency star rat
20、ing, performance requirements, details of energy labels and requirements for valid applications for registration. (e) Part 3 specifies procedures for calculating the performance (simulation) of airconditioners of the vapour compression type up to a rated cooling capacity of 65 kW, for minimum energy
21、 performance standard (MEPS) requirements, in lieu of physical tests. The main changes in this Standard are the introduction of a revised timetable and levels for minimum energy performance standard requirements for single-phase units in the years up to 2008 and the notification of a revised energy
22、labelling algorithm for introduction from 2008. This edition also includes references to Part 1.3 for water sourced heat pumps. The Standard is downloaded from Standard Sharing 3 AS/NZS 3823.2:2005 Similar to the previous revisions of this Standard it is possible to use either physical tests or sim
23、ulated performance tests (described in AS/NZS 3823.3) to demonstrate compliance with the minimum energy performance standard requirements for three-phase and some single- phase units (units which do not carry an energy label). Only physical tests can be used to demonstrate compliance with energy lab
24、elling. Suppliers of three-phase, single-phase ducted and single-phase commercial units may choose to fix energy labels to products; if so, then all of the usual requirements for energy labelling will apply (including the requirement for a physical test). The status of energy labelling and minimum e
25、nergy performance standard (MEPS) Australian regulatory programs and their date of implementation, for the various airconditioning equipment configurations, is provided in Appendix E. This Standard is published with the approval of the combined state and territory regulatory authorities and is struc
26、tured to be suitable for reference in legislation calling up minimum energy performance standards and also for reference in energy labelling regulatory legislation. Key regulatory dates in this Standard and other changes are as follows: (a) The change in scope of the mandatory energy labelling progr
27、am for household airconditioners and heat pumps from a 7.5 kW cooling requirement to a single-phase requirement was 1 October 2001. (b) Introduction of MEPS for three-phase airconditioners was 1 October 2001. (c) Introduction of MEPS for single-phase airconditioners was 1 October 2004. (d) Single-ph
28、ase ducted units, which are registered to any relevant MEPS level under this Standard, may carry an energy label on a voluntary basis. (e) Revised three-phase MEPS levels will be introduced on 1 October 2007 (no change from 2003 edition of this Standard). (f) Single-phase MEPS levels for some catego
29、ries of products originally proposed for 1 October 2007 have been advanced to 1 April 2006 and an additional MEPS level for 1 October 2008 has also been included. (g) Class A efficiency levels will be valid for the next iteration of MEPS after 2008. (h) A minor change to the wording on the energy la
30、bel for variable output compressors. Section 4 of this Standard sets out the transition provisions for energy labelling and MEPS under this Standard. New Zealand Energy Efficiency (Energy Using Products) Regulations 2002 had a commencement date of 1 April 2002 for energy performance labelling of sin
31、gle-phase airconditioners and 1 July 2002 for MEPS for three-phase airconditioners which currently includes only the requirements of the 2003 edition of this Standard. The revised MEPS levels and introductory dates for single phase units in New Zealand will be addressed by an amendment to this Stand
32、ard, which is expected in early 2006. 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 appendix is only for information and guidance. State
33、ments expressed in mandatory terms in notes to figures, are deemed to be requirements of this Standard.
