The AS/NZS 3823 series comprises five Parts, as follows: AS/NZS 3823 Performance of electrical appliances—Airconditioners and heat pumps 3823.1.1 Part 1.1: Test methods—Non-ducted airconditioners and heat pumps—Testing and rating for performance 3823.1.2 Part 1.2: Test methods—Ducted airconditioners and air-to-air heat pumps— Testing and rating for performance 3823.1.3 Part 1.3 Water-source heat pumps—Testing 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. A c c e s s e d b y R M I T U N I V E R S I T Y L I B R A R Y o n 2 9 M a r 2 0 0 6 3 AS/NZS 3823.2:2005 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 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 labelling. 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 energy 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 structured 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 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 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 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 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 single-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 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 ‘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 figures, are deemed to be requirements of this Standard.

Products that have water-cooled condensers as well as water-source heat pumps fall within the scope of this Standard and shall meet the relevant labelling and/or MEPS requirements for the cooling function. For these products, the cooling and heating performance shall be determined and declared in accordance with AS/NZS 3823.1.3. Cooling only products with water-cooled condensers that are included within the scope of AS/NZS 3823.1.1 and AS/NZS 3823.1.2 shall be tested to AS/NZS 3823.1.3 wherever possible. 1.4 OBJECTIVE The objective of this Standard is to— (a) provide detailed information on the performance and energy labelling requirements which an airconditioning appliance has to meet in order to carry a valid energy efficiency label; (b) provide detailed information on the performance requirements which an airconditioning appliance has to meet in order meet minimum energy performance standard requirements; and (c) describe the circumstances in which alternatives to physical testing may be used to demonstrate and verify compliance with minimum energy performance standard requirements. 1.5 REFERENCED DOCUMENTS The following documents are referred to in this Standard: AS 2706 Numerical values—Rounding and interpretation of limiting values 2834 Computer accommodation AS/NZS 3823 Performance of household electrical appliances—Airconditioners and heat pumps 3823.1.1 Part 1.1: Test methods—Non-ducted airconditioners and heat pumps—Testing and rating for performance 3823.1.2 Part 1.2: Test methods—Ducted airconditioners and air-to-air heat pumps— Testing and rating for performance A c c e s s e d b y R M I T U N I V E R S I T Y L I B R A R Y o n 2 9 M a r 2 0 0 6 AS/NZS 3823.2:2005 8 COPYRIGHT 3823.1.3 Part 1.3: Water-source heat pumps—Testing and rating for performance: Water-to-air and brine-to-air heat pumps 3823.3 Part 3: Calculation of performance for minimum energy performance standard (MEPS) requirements 1.6 DEFINITIONS For the purposes of this Standard the definitions given in AS/NZS 3823.1.1, AS/NZS 3823.1.2, AS/NZS 3823.1.3 and those below apply. 1.6.1 Check test A full or part test in accordance with AS/NZS 3823.1.1, AS/NZS 3823.1.2, AS/NZS 3823.1.3 or AS/NZS 3823.3, as applicable, to verify the performance or energy consumption, or both, of an individual model. 1.6.2 Class A efficiency Rating for an airconditioner that meets the minimum EER cooling values specified in Clause 3.3. 1.6.3 Close controlled airconditioners An airconditioner that meets the requirements of AS 2834 for Environment Type 1 conditions and satisfies the requirements of the process carried out in the airconditioned room. 1.6.4 Comparative energy consumption (CEC) The nominal energy consumption of a model of airconditioner. It is the estimate of energy used by a single unit per hour of use at rated power for cooling and/or heating, as applicable. It assumes the unit operates under standard conditions (as defined in AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3) (see also Clause 2.3). The CEC appears on the energy label as ‘Power input’. (Units: kW.) 1.6.5 Ducted airconditioners An airconditioner model configuration where the indoor side is situated remote to the space to be conditioned. The conditioned air is supplied or extracted via a duct. 1.6.6 Family of models A range of models of the one brand, for which a single set of test reports is applicable and where each of the models has the same relevant physical characteristics, comparative energy consumption, energy efficiency rating, performance characteristics and refrigerant. The term ‘model’ is synonymous with ‘family of models’. NOTE: A product that has single-phase and three-phase variants will have to be separately registered and cannot be considered as one family (as MEPS requirements for single- and three- phase variants may be different). Single- and three-phase products may be separately registered using a single test report that covers these variants, as long as the product tested has the lowest EER and COP of all the relevant variants. 1.6.7 Multi-split system A split system airconditioner with a refrigeration system having a single outdoor unit and two or more indoor units, each indoor unit being independently controlled. 1.6.8 Non-ducted airconditioner An airconditioner model configuration where the indoor side is situated partly or wholly within the space to be conditioned. The conditioned air is supplied and extracted directly to and from the conditioned space.

(Units: W or kW.) (b) Rated heating capacity As claimed by the manufacturer in accordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3 for temperature condition H1. (Units: W or kW.) The rated capacity appears on the energy label as ‘Capacity Output’ (heating and/or cooling as applicable. (Units: kW). For variable output capacity equipment, the rated capacity of each model shall not exceed the maximum continuous output rating possible by the unit. Short term peak outputs shall not be used for rated capacity. 1.6.10 Rated power Effective power input of the airconditioner model as claimed by the manufacturer in accordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3 during the determination of rated cooling capacity and rated heating capacity, as applicable. (Units: W or kW.) 1.6.11 Split system An airconditioner with separate indoor and outdoor components that are connected with refrigerant piping. The indoor unit usually lies within the conditioned space and may be installed or portable/mobile. NOTE: The indoor unit in some configurations may feed into a duct system. Some split ducted system indoor units may have no fan and are designed to operate with an existing system (e.g., gas heater). 1.6.12 Spot cooler A unitary airconditioner that lies wholly within a conditioned space and that draws air for both the evaporator and condenser from the conditioned space and expels both of these back into the conditioned space. 1.6.13 Star rating The number of stars displayed on the energy label. Available stars are between a minimum of one and a maximum of six, shown in half star intervals. The star rating is calculated from the Star Rating Index (see Clause 2.6). (Dimensionless.) 1.6.14 Star rating index (SRI) An indication of the claimed energy efficiency of a model at rated conditions. A higher SRI indicates a higher energy efficiency. It is derived from the measured EER or measured COP, as applicable (see Clause 2.5). 1.6.15 Statements of intention 1.6.15.1 Shall Indicates that a statement is mandatory. 1.6.15.2 Should Indicates a recommendation.

NOTE: Some components of an airconditioner system may be supplied a.c. or d.c. power via internal wiring. 1.6.18 Twin (or triple) split A split system airconditioner comprising a single outdoor unit with two (or three) indoor units that are controlled by a single controller. 1.6.19 Unbalanced airconditioner An unbalanced airconditioner is a unitary airconditioner that lies wholly within a conditioned space and that draws air from the conditioned space and expels this to outdoors. An unbalanced airconditioner is usually ducted (where the exhaust air from the heat exchanger is expelled from the conditioned space via a flexible duct, pipe or opening) but may be connected to a pipe or other opening such as a window. These units are typically portable or mobile. 1.6.20 Unitary airconditioner An airconditioner where the evaporator, condenser and associated refrigeration components (e.g., compressor) are contained within a single casing. Unitary airconditioners may be non- ducted (e.g., window/wall units) or ducted (e.g., single packaged units). 1.7 MEASURED QUANTITIES Quantities used in this Standard shall be measured during tests carried out in accordance with AS/NZS 3823.1.1, AS/NZS 3823.1.2, AS/NZS 3823.1.3 or AS/NZS 3823.3, as applicable. 1.8 ROUNDING Unless otherwise stated, numbers shall be rounded and recorded to five significant figures in accordance with AS 2706. 1.9 CLAIMS OF CAPACITY AND ENERGY CONSUMPTION Any unqualified claims of capacity and energy consumption shall be rated values for condition T1 or H1, as applicable (see Clauses 1.6.9 and 1.6.10). Other claims of capacity and energy consumption shall be qualified by the conditions under which these values are determined. The use of 'horsepower' as a unit of measure for air conditioner output capacity shall not be used because it does not directly correlate to the output capacity in kW and is therefore misleading.

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 have records kept for energy labelling. 2.2 GENERAL Energy labels may not be fixed to appliances that do not comply with the requirements of this 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 means of 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 shall be consistent with the capacity on the model’s rating nameplate or all other data in any associated 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 conducted using 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 3823.1.3 Table 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 or heating and, where applicable, capacity, effective power input and COP on heating in accordance with AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3. At the supplier’s 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.

Rated power is in kilowatts. The CEC is determined for cooling and heating, as applicable. 2.5 STAR RATING INDEX (SRI) 2.5.1 General The equations for SRI in the following clauses are derived from a market analysis in 1998 and were introduced in 2000. The revised equations to be introduced in 2008 reflect improvements in airconditioner efficiency achieved since the introduction of Energy Labelling. These are documented in Appendix F. The original air conditioner equations were introduced in 1987.

Appliances with variable output compressors, which do not meet the minimum energy performance 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 EER cooling requirements of this standard if they achieve the minimum required EER when they are 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 3823.1.1 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. 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 where there 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 relevant application 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 to support an application for MEPS shall meet the validity criteria for cooling as set out in Clause 2.3.3. For product registered using simulation to AS/NZS 3823.3, the rated capacity shall not exceed the capacity obtained by simulation.

The report shall demonstrate that each appliance meets or exceeds the minimum EER cooling requirement for the appliance capacity. 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 case of 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 test results 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 criteria below, 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 meets all 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 applicant’s 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 refrigerant temperatures 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 air flow rates) specified in the application for registration for MEPS and energy labelling (where applicable).

These products may also claim EER and COP figures (as applicable) at 50% of the rated capacity for CONDITIONS TI and HI in AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3 (as applicable) for display on the www.energyrating.gov.au website. Performance data shall be displayed on the website only when the claim is supported by test data at the time of registration or listing. NOTE: Such products can have a high relative efficiency at part load. If these products are identified to the relevant regulatory authority and supporting test data is provided, the part load performance figures will be displayed on the www.energyrating.gov.au website. Generally, an output in the range of 50% to 60% is acceptable for this listing. 3.9 COEFFICIENT OF PERFORMANCE AT LOW TEMPERATURE NOTE: Minimum coefficient of performance of heat pumps at low ambient temperature is under consideration by regulatory authorities. 3.10 STANDBY POWER AND CRANK CASE HEATERS All products shall have the following data measured for the model as set out in AS/NZS 3823.1.1 or AS/NZS 3823.1.2 or AS/NZS 3823.1.3 (as applicable): (a) Off mode power consumption (Watts). (b) Passive standby mode power consumption, where applicable (Watts). (c) Whether or not the product has any form of crank case heating. (d) Where a crank case heater is present, the average crank case heater power consumption under outdoor conditions specified in the relevant standards for all airconditioner types (i.e., whether cooling only, heating only or reverse cycle). During registration or listing, the above data shall be provided as set out in Appendix C. Relevant data will be displayed on the www.energyrating.gov.au website. 3.11 LOAD CONTROL CAPABILITY Planning is under way to mandate facilities for external load control and communications capability for certain airconditioner types within the scope of this standard. These will be included in a future amendment to this Standard. 3.12 POWER FACTOR The average power factor during cooling and heating capacity rating tests shall be reported for all products.

The most up to date version can be obtained from the www.energyrating.gov.au website. 4.1.5 Energy label transitions Regulators 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 with energy labels to previous editions of this Standard which are manufactured or imported prior to the relevant MEPS implementation 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 2008 (refer Appendix F) and all products will require re-registration and new labels as defined in a future edition of this Standard from that date. Special provisions will apply to products on display in retailers during the 2008 energy transition. 4.1.6 Duration of registration Registrations for energy labelling and MEPS may have a validity of up to 5 years. Registration expiry dates are reviewed annually and records may be extended (up to the 5 year limit in 1 year increments) where there is no forthcoming change to regulatory requirements. Registrations of single phase products to previous editions of this Standard will expire no later than 30 September 2008.

Paragraphs A2 and A3 show the calculations involved in the determination of the energy label details for a hypothetical single-phase reverse cycle household airconditioner for MEPS and energy labelling and the determination of CEC, SRI and star rating. Paragraph A4 shows the calculations 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 is considered 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 A1 and 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 MEPS compliance. A2.1 Verification of MEPS requirements In order to verify that this particular model complies with MEPS, the unit is required to exceed the MEPS levels for that model as listed in Table 3.1. The tested EER in Table A1 is 2.689 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 not support 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 values as specified in Clause 2.3.3. For capacity and effective power input, the test value for the test 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 in Tables A3 and A4.

A c c e s s e d b y R M I T U N I V E R S I T Y L I B R A R Y o n 2 9 M a r 2 0 0 6 33 AS/NZS 3823.2:2005 COPYRIGHT TABLE A4 VERIFICATION OF RATED HEATING SPECIFICATIONS— (PROPORTION OF RATED RESULT) Tested/Rated Unit 1 Verification limit for each unit Heating capacity 1.005 ≥ 0.95 Effective power input 1.037 ≤ 1.05 NOTES: 1 The tested value for heating capacity is greater than 0.95 of the rated capacity for each unit, so the rated capacity is valid. 2 The tested value for effective power input is less than 1.05 the rated power for each unit, so the rated power is valid. 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.

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 a result of 28.0 kW heating capacity and an effective power input of 9.9 kW, yielding a tested COP 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 effective power 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 claimed values 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 than 2.45, 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.

These will be introduced in early 2008 and will apply to all products registered from April 2008. A transition period for the new label for product on display will apply until late 2008. SRI cooling—2008 The SRI cooling is calculated by the following equation: SRI cooling = [(Tested average EER × 8) −18]/4 . . . F(1) SRI heating—2008 The SRI for heating is calculated by the following equation: SRI heating = [(Tested average COP × 8) −18]/4 . . . F(2) This equates to a 1 star line at and EER/COP of 2.75 with an increase of 0.5 per additional star. These equations have been revised for adoption with the more stringent MEPS levels come into force in late 2008. These equations and associated changes to the energy label will be included in a revision of this Standard in 2006/2007.
