From July 1, 2009 Water and Air Cooled Packaged Water Chillers of 350 Kw in capacity and above are regulated for MEPS in Australia and New Zealand. The MEPS and compliance requirements are covered in AS/NZS 4776.2-2008. The method for Rating is covered in AS/NZS 4776 1.1-2008 and the method for Testing is covered in AS/NZS 4776 1.2-2008. Registration of products can be done on line at http://reg.energyrating.gov.au.
All chillers that are to be imported or manufactured in Australia and New Zealand after July 1, 2009 must be registered before being imported or sold.
A-The Standards cover water and air cooled packaged chillers with a capacity of 350kW and above:
B-The Standards do not cover:
C- The standards cover both full-load and part load performance
Note: that the referenced Standards are published jointly by Standards Australia and Standards New Zealand and are available from SAI Global www.saiglobal.com
The Rating and Testing Standards of the Air-Conditioning, Heating and Refrigeration Institute of the USA and the European Committee of Air Handling and Refrigeration Equipment Manufactures (Eurovent) were used as a basis for the Australian/New Zealand Standards. The objective of the Rating Standard is to establish methods of rating the performance of factory made liquid-chilling packages using the vapour compression cycle.
The objective of the Testing Standard is to prescribe the method of testing liquid-chilling packages using the vapour compression cycle to determine the capacity, power and efficiency of equipment under a specific set of conditions.
It is not the intent of this Standard to provide for testing in-field installations, where steady state and uniform conditions are difficult to achieve and provisions for measurements are not made.
The objectives of the MEPS Standard is to-
When rated and tested in accordance with AS/NZS 4776, Parts 1.1 and 1.2, the efficiency levels shall be not lower than those defined in Table 1. Future proposed efficiency levels are shown in Table 2.

| NOTE: Above capacities of 499, 699, 999 and 1499 cover all decimal values up to the next whole number.For liquid-chilling packages operating under non-standard rating conditions as define in Part 1.1, the MEPS COP and IPLV levels are adjusted in accordance with Appendix E. | ||||

| NOTE: 1. Path A is intended for applications where significant operating time is expected at full load and design ambient conditions. On the other hand, Path B is an alternative set of efficiency levels for water-cooled liquid-chilling packages intended for applications where significant time is expected at part load. All Path B liquid-chilling packages are required to be equipped with demand limiting controls. Compliance with the Standard can be achieved by either meeting the requirements of Path A or Path B. However, both full load and IPLV levels must be met to fulfil the requirements of Path A or Path B. 2. Above capacities of 499, 699, 999 and 1499 cover all decimal values up to the next whole number. |

In the case of liquid-chilling packages using vapour compression cycles that are listed on the AHRI website (www.ari.org) or the Eurovent website (www.euroventcertification.com), suppliers shall register each model using the form (in accordance with Appendix A) provided on the www.energyrating.gov.au website.
Products not certified by AHRI or Eurovent(a) Products from a range part of which is certified by AHRI or Eurovent In the case of liquid-chilling packages from a range that includes products listed on the AHRI website (www.ari.org) or the Eurovent website (www.eurovent-certification.com) but that are themselves outside of the scope of these programs owing to their capacity range or power supply frequency, suppliers shall register each model using the form (in accordance with Appendix B) provided on the www.energyrating.gov.au website. Products that qualify under this category shall have the same generic model number as the certified products in the range and shall also be manufactured at the same facility as the certified products in the range.
(b) Products from a range none of which is certified by AHRI or Eurovent In the case of liquid-chilling packages other than those specified in Clauses 6.2.1 and 6.2.2(a), suppliers shall register each model using the form (in accordance with Appendix C) provided on the www.energyrating.gov.au website. For such products, a test report prepared in accordance with AS/NZS 4776.1.1 and AS/NZS 4776.1.2 shall be provided. A sample of such a test report is provided in Section C6.
NOTE: For registration, contact the relevant state regulatory authority.
This letter, offering some clarification on the registration requirements for rental chillers, from the Chair of the Equipment Energy Efficiency Committee, was distributed to Commercial Building Chiller stakeholders in August 2009.
