Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology andsystems. To maintain their currency, all Standards are periodically reviewed, andnew editions are published. Between editions, amendments may be issued.Standards may also be withdrawn. It is important that readers assure themselvesthey are using a current Standard, which should include any amendments whichmay have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found byvisiting the Standards Web Shop at www.standards.com.au or Standards NewZealand web site at www.standards.co.nz and looking up the relevant Standard inthe on-line catalogue.

Alternatively, both organizations publish an annual printed Catalogue with fulldetails of all current Standards. For more frequent listings or notification ofrevisions, amendments and withdrawals, Standards Australia and Standards NewZealand offer a number of update options.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand

Committee EL-15, Quality and Performance of Household Electrical Appliances, tosupersede AS/NZS 3823.2:2003 (including Amendment 1).

The AS/NZS 3823 series 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 pumps

Testing and rating for performance

3823.1.3 Part 1.3 Water-source heat pumpsTesting and rating for performance:

Water-to-air and brine-to-air heat pumps

3823.2 Part 2: Energy labelling and minimum energy performance standard (MEPS)requirements (this Standard)

3823.3 Part 3: Calculation of performance 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 1.1 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 performance 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 rating,

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 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 labelling algorithm for introduction from

2008. This edition also includes references to Part 1.3 for water sourced heat pumps.

Similar to the previous revisions of this Standard it is possible to use either physical tests or

simulated performance tests (described in AS/NZS 3823.3) to demonstrate compliance withthe 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 todemonstrate compliance with energy labelling. Suppliers of three-phase, single-phase

ducted and single-phase commercial units may choose to fix energy labels to products; ifso, then all of the usual requirements for energy labelling will apply (including therequirement for a physical test). The status of energy labelling and minimum energyperformance 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 structured to be suitable for reference in legislation calling up minimum

energy performance standards and also for reference in energy labelling regulatorylegislation.

Key regulatory dates in this Standard and other changes are as follows:(a) The change in scope of the mandatory energy labelling program 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-phase ducted units, which are registered to any relevant MEPS level under thisStandard, 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 categories 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 label for variable output compressors.

Section 4 of this Standard sets out the transition provisions for energy labelling and MEPSunder this Standard.

New Zealand Energy Efficiency (Energy Using Products) Regulations 2002 had a

commencement date of 1 April 2002 for energy performance labelling of single-phaseairconditioners and 1 July 2002 for MEPS for three-phase airconditioners which currentlyincludes 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 anamendment to this Standard, 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 normativeappendix is an integral partof a Standard, whereas an informativeappendix is only for information and guidance.

Statements expressed in mandatory terms in notes to figures, are deemed to be requirements

of this Standard.

2.1 SCOPE

This Section sets out the equations and procedures for calculating the CEC, SRI values andthe star rating, which appear on an energy label. This Section applies to all single-phase

non-ducted appliances that fall within the Scope of this Standard, and to three-phase

appliances and ducted single-phase appliances which the supplier elects to register or haverecords kept for energy labelling.

2.2 GENERAL

Energy labels may not be fixed to appliances that do not comply with the requirements ofthis Section. Energy labels are provided for cooling only units, heating only units and

heating and cooling units. Units that have the capability to both heat and cool shall be

labelled as a heating and cooling unit, except where the heating is provided only by meansof resistive heating, in which case it shall be labelled as cooling only (refer to Clause 5.3.4).

The capacity and energy values shown on the energy label are based on the rated capacity

and the rated power, as claimed by the manufacturer. The values on the energy label shallbe consistent with the capacity on the models rating nameplate or all other data in anyassociated product literature (or both) for the specified conditions. The Star Rating Index of

the airconditioner shall be based on the tested average energy efficiency ratio (EER), and

the tested average coefficient of performance (COP), as applicable, for the unit(s) tested.

The results of the unit(s) tested are used to assess the validity of the rated capacity and the

rated power. The determination of tested capacity (cooling and heating) and tested total

power input for the unit(s) used for the purposes of energy labelling shall be conductedusing the calorimeter test method as specified in AS/NZS 3823.1.1 or AS/NZS 3823.1.2 for

condition T1 for cooling or condition H1 for heating, as applicable, or AS/NZS 3823.1.3Table 1 for cooling and Table 2 for heating. Determinations using the outdoor air-

enthalpy/psychrometric test method of these Standards or determinations using the

simulation method specified in AS/NZS 3823 are not acceptable.

2.3 NUMBER OF TESTS AND PROCESSING OF DATA

2.3.1 Number of units required

For the purposes of verification of the rated values of a model at least one unit of the

nominated model shall be tested for capacity, effective power input and EER on cooling orheating and, where applicable, capacity, effective power input and COP on heating inaccordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3. At the

suppliers discretion more than one unit may be tested.

2.3.2 Number of tests per unit

Only one valid test from each unit tested shall be considered when determining the energy

label data in accordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3.

2.3.3 Verification of rated values

As a prerequisite to the determination of values for an energy label, the unit(s) tested shall

each comply with the following validity criteria for cooling and heating, as applicable:

(a) Tested effective power input for each unit ......... .......... ......... ...... 1.05 rated power.

(b) Tested cooling and heating capacity for each unit .......... ......... . 0.95 rated capacity.Accessedb

3.4 TEST CONDITIONS FOR DETERMINING MINIMUM ENERGY

PERFORMANCE STANDARDS AND HIGH EFFICIENCY CLAIMS

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 orAS/NZS 3823.1.3 for the determination of cooling capacity, effective power input, energy

efficiency ratio and compliance with minimum EER cooling requirements.

Appliances with variable output compressors, which do not meet the minimum energyperformance standard requirements at rated capacity under CONDITION T1 in

AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3, may be tested at part load

operation. Variable output compressors shall be deemed to comply with the minimum EERcooling requirements of this standard if they achieve the minimum required EER when theyare operated at not less than 50% of their rated cooling capacity, under CONDITION T1. A

separate test report with supporting data is required if compliance with MEPS is not at

100% of rated capacity.

3.5 NUMBER OF TESTS AND PROCESSING OF DATA

For the purposes of demonstrating compliance with minimum energy performance standard

requirements a report shall be prepared as follows:

(a) For units registered for energy labelling (on either a mandatory or voluntary basis)and MEPS: one physical test conducted in accordance with AS/NZS 3823.1.1 or

AS/NZS 3823.1.2 for CONDITION T1 for cooling and CONDITION H1 for heating,or one physical test conducted in accordance with AS/NZS 3823.1.3 to Table 1 for

cooling and Table 2 for heating, as applicable:

or

(b) For units registered for MEPS only: either a simulation of performance as specified in

AS/NZS 3823.3, or one physical test conducted in accordance with ASNZS 3823.1.1or AS/NZS 3823.1.2 for CONDITION T1 for cooling and CONDITION H1 for

heating, or one physical test conducted in accordance with AS/NZS 3823.1.3 to Table1 for cooling and Table 2 for heating, as applicable.

Where appliances are of a configuration not within the scope of AS/NZS 3823.3 (e.g.,

where technology that cannot be accurately modelled is used, such as unitary systems wherethere is thermal interaction between internal components, water cooled units, non steady

state behaviour such as defrosting) there is no alternative to a physical test.

The applicability of energy labelling and MEPS program elements together with relevantapplication dates shall be in accordance with the provisions of Appendix E.

As a prerequisite to the verification of MEPS compliance, any physical test result used tosupport an application for MEPS shall meet the validity criteria for cooling as set out inClause 2.3.3. For product registered using simulation to AS/NZS 3823.3, the rated capacity

shall not exceed the capacity obtained by simulation.

3.6 MINIMUM ENERGY PERFORMANCE STANDARD REQUIREMENTS

COMPLIANCE

Evidence of minimum energy performance standard requirements compliance can be

provided by a report on a physical test to AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or

AS/NZS 3823.1.3 requirements or for certain product types a report on a simulation test toAS/NZS 3823.3 requirements as specified in Clause 3.5. The report shall demonstrate that

each appliance meets or exceeds the minimum EER cooling requirement for the appliancecapacity. The claimed capacity and power consumption for both cooling and heating, if

applicable, shall be substantiated by physical testing or simulation of appliance

performance for the standard rating conditions set out in Clause 3.5.

NOTE: An example of airconditioner assessment for MEPS is provided in Appendix A.

3.7 MEPS VALIDITY (CHECK TESTING)

Check testing of a product may be either by a physical test or a simulation test. In the caseof dispute, test results obtained by physical testing, using the procedures defined in

AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3, take precedence over testresults obtained using a simulation model. In the case of a physical test, check testing will

be undertaken using the calorimeter method wherever possible as this provides a more

reliable result for verification purposes.

Generally a screening test is conducted on a single model and if this fails any of the criteriabelow, up to 3 additional units are tested in Stage 2. The rated data shall be accepted as

valid if the product satisfies the EER requirement and data from the verification test meetsall of the following criteria.

(a) Tested effective power input ......... .......... ......... ......... ......... ........ 1.10 rated power.

(b) Tested cooling and heating capacity .......... ......... ......... ......... ... 0.90 rated capacity.

(c) Tested EER .......................................................MEPS limit and 0.90 rated EER.

(d) Tested COP ..................................................................................0.90 rated COP.

NOTES:

1 Simulation models provide an estimate of system optimum performance under idealized

operating conditions. Modelling may not take into account variables introduced in the

physical manufacture of a system, such as airflow across the coils. For this reason actual tests

may show a performance lower than that estimated by the simulation model. Physical tests

take priority in this Standard and performance claims based on a simulation model are made

at the applicants own risk.

2 More details on check testing and validity criteria can be found in the Administrative

Guidelines. The most up to date version can be obtained from the www.energyrating.gov.au

website.

Where a physical check test is undertaken to validate a registration, the laboratory should

provide all relevant physical measurements (such as pressure drops and refrigeranttemperatures etc.) that will allow the physical check test to be fully compared with the

original test report or the simulation result (refer to Appendix C).

Check testing will be undertaken using the conditions (e.g. settings, duct pressure and airflow rates) specified in the application for registration for MEPS and energy labelling

(where applicable).

APPENDIX A

EXAMPLES OF ENERGY EFFICIENCY CALCULATIONS

(Informative)

A1 GENERAL

This Appendix provides an example of energy efficiency calculations. Paragraphs A2 andA3 show the calculations involved in the determination of the energy label details for a

hypothetical single-phase reverse cycle household airconditioner for MEPS and energylabelling and the determination of CEC, SRI and star rating. Paragraph A4 shows thecalculations involved in the determination of MEPS testing and compliance for a

hypothetical reverse-cycle three-phase split packaged airconditioner.

A2 TEST RESULTS, AVERAGES AND RATED VALUES

A hypothetical single-phase reverse cycle window/wall household airconditioner isconsidered for MEPS and energy labelling.

On cooling, it has a rated capacity of 4.45 kW with a rated power input of 1.61 kW.

On heating, it has a rated capacity of 4.75 kW with a rated power input of 1.64 kW.

This unit is a single-phase airconditioner within the scope of AS/NZS 3823.1.1 and

according to Appendix E, compliance requirements are for labelling and MEPS (L).

Data from testing one sample in accordance with AS/NZS 3823.1.1 is shown in Tables A1and A2. Values are for CONDITION T1 for cooling and CONDITION H1 for heating.

Before the energy labelling details are calculated, the unit should be checked for MEPScompliance.

A2.1 Verification of MEPS requirements

In order to verify that this particular model complies with MEPS, the unit is required toexceed the MEPS levels for that model as listed in Table 3.1. The tested EER in Table A1 is2.689 while the rated EER is 2.764.

This unit complies with the MEPS requirements for 2004 (single-phase reverse cycle non-ducted) as the rated and tested EER exceed the minimum EER specified in Table 3.1 (i.e.,EER >2.3). While the rated value for EER just meets the MEPS 2006 requirements for

single-phase non-ducted non-split reverse cycle (i.e., EER >2.75), the test result does notsupport this claim, so compliance with this requirement cannot be claimed.

A2.2 Verification of rated values

The test results should now be analysed to ensure that they verify the claimed rated valuesas specified in Clause 2.3.3. For capacity and effective power input, the test value for thetest unit is compared with the rated values to ensure that they lie within the required units.

A summary of the verification comparisons for cooling and heating are contained inTables A3 and A4.

A3 CALCULATION OF ENERGY LABEL VALUES

A3.1 Calculation of comparative energy consumption (CEC)

When the rated specifications have been verified, the CEC can be calculated from the rated

power.

CEC is calculated in accordance with Clause 2.4.

Example:

(a) CEC cooling = rated power

= 1.61 kW

(b) CEC heating = rated power

= 1.64 kW

A3.2 Calculation of Star Rating Index (SRI)

SRI for cooling and heating are calculated from the applicable equations in Clause 2.5.Note that the tested values for EER and COP (not the rated values) are used to calculate

SRI.

Example:(a) SRI cooling = [ (EERav 10)17 ] / 3

= [ (2.689 10) 17 ] / 3

= 3.2967

(b) SRI heating = [ (COPav 10) 20 ] / 3

= [ (2.805 10) 20 ] / 3

= 2.6833

Star rating is as given in Table 2.1. Therefore, the cooling star rating for this model is 3.0

and the heating star rating for this model is 2.5.

A4 MEPS FOR AIRCONDITIONERS

A hypothetical reverse cycle three-phase split packaged airconditioner is considered forMEPS.

On cooling, it has a rated capacity of 23.3 kW with a rated power input of 9.2 kW.

On heating, it has a rated capacity of 28.6 kW with a rated power input of 9.7 kW.

This unit is an airconditioner within the scope of AS/NZS 3823.1.1 and according to

Appendix E, and compliance requirements are for MEPS (M).

Data from testing a single sample in accordance with AS/NZS 3823.1.1 yields a result of

22.9 kW cooling capacity and an effective power input of 9.31 kW, yielding a tested EER

of 2.4597. Data from testing a single sample in accordance with AS/NZS 3823.1.1 yields aresult of 28.0 kW heating capacity and an effective power input of 9.9 kW, yielding a testedCOP of 2.8283.

Before MEPS compliance is verified, the test results should be analysed to ensure that they

verify the claimed rated values as specified in Clause 2.3.3. For capacity and effectivepower input, the test values for each test unit are compared with the rated values to ensure

that they lie within the required limits. In this case the measured cooling capacity is 0.983

of the rated value and the effective power input is 1.012 of the rated value, so the claimedvalues are valid. Similarly, the claimed heating results are valid.

The rated capacity of the model is 23.3 kW, therefore from Table 3.1 the MEPS 2001

requirement is that EER shall be > 2.45. As the tested value is 2.4597, which is greater than2.45, the model complies with MEPS 2001. This unit does not comply with the MEPS

requirements for 2007, or the Class A Efficiency requirements specified in Table 3.3.
