13、tandards Australia/Standards New Zealand Committee EL/15, Quality and Performance of Household Electrical Appliances. This Standard incorporates Amendment No. 1 (September 2006) and Amendment No. 2 (April 2007). The changes required by the Amendments are indicated in the text by a marginal bar and a
14、mendment number against the clause, note, table, figure or part thereof affected. The AS/NZS 2442 series is comprised of two Parts as follows: AS/NZS 2442 Performance of household electrical appliancesRotary clothes dryers 2442.1 Part 1: Energy consumption and performance 2442.2 Part 2: Energy label
15、ling requirements (this Standard) The overall objective of the AS/NZS 2442 series of Standards is to promote high levels of quality, performance and energy efficiency in rotary clothes dryers. The Parts of AS/NZS 2442 are summarized as follows: (a) Part 1 Includes performance test procedures and min
16、imum performance criteria for rotary clothes dryers. (b) Part 2 Includes algorithms for the calculation of the energy efficiency star rating and projected energy usage, performance requirements, details of the energy label and requirements for the valid application thereof. It has been structured to
17、 be suitable for reference in regulatory legislation and to be used in conjunction with Part 1. This edition contains the new star rating algorithms developed during 1999 which will be introduced together with the new energy label for clothes dryers during mid to late 2000. Part 1 of this Standard r
18、emains largely unchanged, except for some amendments which have been passed subsequent to its original publication (including a change in the ambient temperature from 23C to 20C to align with clothes washers and dishwashers and changes to the test procedure for the maximum temperature test for autos
19、ensing dryers). The main changes in this Part 2 Standard are as follows: (i) Introduction of new energy labelling algorithms to regrade star ratings. (ii) Introduction of redesigned more consumer friendly energy label. The terms normative and informative have been used in this Standard to define the
20、 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. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard. This
21、Standard is published with the approval of 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. All registrations submitted and records kept from 1 October 2000 will require test
22、reports in accordance with AS/NZS 2442.1. Check testing, where applicable, will be undertaken to the version of the test standard which has been used to support the current energy label for that model.

The process consists of measuring the tested energy cons
45、umption (Et) and moisture removed (mr) of each unit tested, then calculating the tested energy performance (TEP) and the projected annual energy consumption (PAEC) of the unit. The values of PAEC for the units tested are used to determine the comparative energy consumption (CEC) for the model. The C
46、EC and the rated capacity are then used to calculate the star rating index (SRI) and hence the star rating. NOTE: For examples of energy efficiency calculations, see Appendix A. 2.2 NUMBER OF TESTS AND PROCESSING OF DATA 2.2.1 Number of units required For the purpose of determining the CEC of a mode
47、l, three separate units of a nominated model shall be tested for energy consumption in accordance with AS/NZS 2442.1. At the suppliers discretion, more than three units may be tested. 2.2.2 Number of tests per unit Each unit shall be subjected to at least one test run to obtain a valid value for eac
48、h of Et for that unit. This determination shall be documented in a test report. (Refer to AS/NZS 2442.1). 2.2.3 Multiple test runs Where more than one test run is performed on a unit, the values of Et and mr shall be recorded for each run. For subsequent calculations, the values of Et and mr shall e
49、ach be averaged and treated as the result for that unit. 2.2.4 Results After testing three or more separate units in accordance with Clause 2.2.1, the separate values of mr and PAEC shall be averaged and referred to as mr(av.) and PAECav respectively. 2.3 PROJECTED ANNUAL ENERGY CONSUMPTION The PAEC for a single clothes dryer unit is given by the following equation: PAEC = 52 Ff Et (kWh/year) . . . 2(1) where Ff = field use factor. It accounts for the over-drying of clothes by timer and manual dryers. (It
