AS/NZS 3823.2:2001
Performance of electrical appliances - Airconditioners and heat pumps - Energy labelling and minimum energy performance standard (MEPS) requirements
Specifies the energy labelling requirements for single-phase ducted and non-ducted airconditioners of the vapour compression type intended for household and similar use. The Standard also specifies minimum energy performance standard (MEPS) requirements for three-phase ducted and non-ducted airconditioners of the vapour compression type intended for household, commercial and similar use, up to a rated cooling capacity of 65 kW. It does not cover multi-split systems or evaporative airconditioners. This Standard does not specify electrical safety requirements.

1.5.6 Rated power
1.5.7 Star rating
1.5.8 Statements of intention
1.5.8.1 Shall
1.5.8.2 Should
1.6 MEASURED QUANTITIES
1.7 ROUNDING
SECTION 2 CALCULATIONS FOR THE ENERGY LABEL
2.1 SCOPE
2.2 GENERAL
2.3 NUMBER OF TESTS AND PROCESSING OF DATA
2.3.1 Number of units required
2.3.2 Number of tests per unit
2.3.3 Verification of rated values
2.4 COMPARATIVE ENERGY CONSUMPTION (CEC)
2.5 STAR RATING INDEX (SRI)
NOTE: The equations for SRI in the following clauses are derived from a market analysis and reflect improvements in airconditioner efficiency achieved since the introduction of Energy Labelling.
2.5.1 General
2.5.2 SRI cooling
2.5.3 SRI heating
2.6 STAR RATING
2.7 EXAMPLE OF ENERGY EFFICIENCY CALCULATIONS
NOTE: For a complete example of calculations carried out on a typical set of test results refer to Appendix A.
2.8 ENERGY LABEL VALIDITY
SECTION 3 PERFORMANCE CRITERIA
3.1 GENERAL
NOTE: Where a system has more than one power supply (e.g. a split system), the whole system is considered to be three phase for the purposes of this Standard where at least one of the power supply systems are three phase.
3.2 MAXIMUM COOLING TEST

3.4 TEST CONDITIONS FOR DETERMINING MINIMUM ENERGY PERFORMANCE STANDARD OF THREE PHASE APPLIANCES
3.5 NUMBER OF TESTS AND PROCESSING OF DATA
3.6 MINIMUM ENERGY PERFORMANCE STANDARD REQUIREMENTS COMPLIANCE
NOTE: An example of airconditioner assessment for MEPS is provided in Appendix A.
3.7 CHECK TESTING
NOTE: 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, variables such as airflow across the coi...
SECTION 4 APPLICATION AND TEST RESULT FORMATS
4.1 APPLICATION FOR REGISTRATION
4.1.1 General
NOTE: Three phase heating only models do not require registration; however, data to support claimed performance are still required under Clause 4.2.
4.1.2 Registration
NOTES:
NOTE: Details of the relevant regulatory bodies are available from www.energyrating.gov.au.
4.1.3 Test report
