3、s Association Keeping Standards up-to-date Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be
4、withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Detailed information about Standards can be found by visiting the Standards Australia web site at .au and l
5、ooking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Global Standard, has a full listing of revisions and amendments published each month. We also welcome suggestions for impr
6、ovement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities.

9、Standard was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee ME-008, Refrigerated Display Cabinets, to supersede AS 1731.92000, Refrigerated display cabinets, Part 9: Electrical energy consumption test. After consultation with stakeholders in both
10、countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian, rather than an Australian/New Zealand Standard. This Standard is based on International Standard prEN ISO 23953-2:2003, Refrigerated display cabinets, Part 2: Classification, requirements and
11、test conditions. The Standard is Part 9 of a series of Standards on refrigerated display cabinets, as follows: AS 1731 Refrigerated display cabinets 1731.1 Part 1: Terms and definitions 1731.2 Part 2: General mechanical and physical requirements 1731.3 Part 3: Linear dimensions, areas and volumes 17

15、 Scope of Standard This Standard specifies terminology, general mechanical and physical requirements, test conditions as well as installation and maintenance, including a users guide, for refrigerated display cabinets for the sale or display, or both, of food products. This Standard does not cover r
16、efrigerated vending machines, cabinets intended for use in catering or similar non-retail applications, or food service cabinets. 1.2 Scope of Part 9 This Part of AS 1731 specifies the method of measuring the consumption of electrical energy of refrigerated display cabinets. 2 REFERENCED DOCUMENTS T
17、he following documents are referred in this Standard. AS 1731 Refrigerated display cabinets 1731.4 Part 4: General test conditions 1731.5 Part 5: Temperature test 1731.13 Part 13: Test report 3 OBJECTIVE The objective of this Standard is to establish a procedure for testing energy consumption in ref
18、rigerated display cabinets for use by manufacturers, suppliers, purchasers, operators and regulators of these systems. 4 TEST PROCEDURE 4.1 Test conditions Locate, load and operate the cabinet as for the temperature test (see AS 1731.4 and AS 1731.5) and in accordance with the manufacturers instruct
19、ions at the conditions appropriate to the test room climate class for which it is intended, in accordance with Clause 4.4. NOTE: This test may be carried out concurrently with the temperature test. 4.2 Lighting For cabinets supplied without night-covers, any built-in cabinet lighting shall be on con
20、tinuously during the test. 5 AS 1731.92003 .au Standards Australia 4.3 Night-covers Where night-covers are supplied, the night-covers and cabinet lighting shall be manipulated as follows: (a) First test Night-covers removed and cabinet lighting on continuously during the test period of 24 h. (b) Sec
21、ond test Night-covers removed and cabinet lighting switched on for a period of 12 h followed by a period of 12 h with the night-covers on and the cabinet lighting switched off. 4.4 Test period After the run-in period, the energy consumption shall be recorded for a test period beginning and ending at
22、 corresponding points on the time/temperature cycle. The duration of the test period shall be as follows: (a) Not less than 12 h for cabinets intended to be switched off at night. (b) Not less than 48 h for closed refrigerated cabinets under stable conditions. (c) Not less than 24 h for all other ca
23、binets under stable conditions. For all condensing units that are installed remote from the cabinet and for those applications in which the cabinet manufacturer specifies a suitable condensing unit, sufficient measurements shall be made during the test period, in accordance with AS 1731.4, to establ
24、ish that the actual heat extraction rate conforms to that stated by the cabinet manufacturer, for the operating conditions specified. 5 MEASUREMENTS 5.1 Cabinets fitted with incorporated condensing unit For cabinets with incorporated condensing unit the direct energy consumption (DEC) equals the tot
25、al energy consumption (TEC), as it includes the compressor energy consumption. REC is not defined for these cabinets. The TEC, here including the compressor energy consumption, reported in kWh/24 h, the compressor switching on/off frequency and the relative running time (ratio of running time to ove
26、rall duration of a measurement cycle) shall be measured; i.e., with all fitted electrical power-using components switched on. 5.2 Cabinets with remote condensing unit For cabinets with remote condensing unit the DEC does not include the refrigeration electrical energy consumption (REC). The DEC of t
27、he cabinet only shall be measured; i.e., with all fitted electrical power-using components switched on. The DEC recorded for each test shall be the summation of all electrical energy consumed by the refrigerated cabinet without the control unit during the test period. NOTE: If, for technical reasons
28、, it is too difficult to measure separately the component powers, it is possible to use the DEC directly measured. AS 1731.92003 6 Standards Australia .au 6 TEST REPORT The test report shall be as described in AS 1731.13. C6 Typical information that should be included in the test report is: (a) The
29、manufacturers name or trademark, or both. (b) The model and serial number of the cabinet, as well as the description of its internal fittings. (c) The test room climate class for which the cabinet is intended and in which the test has been made. (d) The method of temperature control, defrost process
30、, defrost termination, setting parameters and sensor locations. (e) Whether the test was made with or without night-covers. (f) The total energy consumption of the refrigerated cabinet during the test, expressed in kilowatt hours per 24 h. (g) The relative running time. (h) Reference to this test me

These standards are developed through a
32、n open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth government, Standards Australia is recognized as Australias peak national standards body. Australian Standards Australian Standards ar
33、e prepared by committees of experts from industry, governments, consumers and other relevant sectors. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They refl
34、ect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology. International Involvement Standards Australia is responsible for ensuring that the Australian viewpoint is cons
35、idered in the formulation of international Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both ISO (The International Organiz
36、ation for Standardization) and the International Electrotechnical Commission (IEC). Electronic Standards All Australian Standards are available in electronic editions, either downloaded individually from our Web site, or via on-line and CD ROM subscription services.
