For Suppliers

Commercial refrigeration applications include refrigerated cabinets, walk-in coolrooms, industrial cold storage, beverage cooling, vending machines and ice makers. 

Overview

Commercial or non-domestic refrigeration applications span a wide range of processes and applications in the food chain and consume approximately the same quantity of electricity as the combined total of all residential lighting and refrigeration in Australia and New Zealand.  Commercial refrigeration is estimated to account for 4% of emissions from Australia’s energy sector and 6% of emissions in New Zealand.

Examples of technologies include refrigerated cabinets, walk-in coolrooms, industrial cold storage, beverage cooling, vending machines and ice makers. End users  that would benefit from improved energy efficiency measures include supermarkets, food processer’s, dairy industry fishing fleets, schools, cafes and restaurants and refrigerated transport.

A ten year strategy for commercial refrigeration products, outlined in the paper “In From The Cold” and jointly developed by Australian and New Zealand governments, aims to improve the energy efficiency of equipment throughout the sector. By facilitating a market transformation, the strategy will deliver increased energy efficiency of systems, components and refrigerants.

As shown in Figure 1, the electricity consumption of commercial refrigeration is largest in supermarkets, and process and cold storage.

Current Commercial Refrigeration Work

Refrigerated display cabinets (RDCs) and refrigerated storage cabinets (RSCs) are used in supermarkets, petrol stations and smaller food and beverage vendors such as ‘corner stores’ and delicatessens to chill food and drink for sale. These technologies are a significant component of the supermarket and process & cold storage sectors. Some types of RDCs have been regulated for their energy use since 2004 with Minimum Energy Performance Standards (MEPS). Any increase or introduction of minimum energy performance standards will be subject to costs and benefits assessment and consultation

The E3 committee is focusing its efforts on energy efficiency improvements for these appliances.

Types of Refrigerated Cabinet Technologies

Refrigerated Display Cabinets (RDCs)

Refrigerated Display Cabinets (RDCs) are intended to store and display for sale chilled and/or frozen foodstuffs and beverages. These cabinets allow the stored products to be either directly viewed through an opening in the cabinet or through transparent doors, lids or covers. The doors are normally kept closed but enable users to access any of the contents without stepping inside the refrigerated space. They are typically used in retail applications such as supermarkets, petrol stations, liquor outlets and smaller food and beverage vendors such as ‘corner stores’, ‘dairies’ and delicatessens.

 

Refrigerated Storage Cabinets (RSCs)

Refrigerated Storage Cabinets (RSCs) are specifically designed to store, but not to display for sale, chilled and/or frozen foodstuffs. They predominantly have solid faced doors, lids or drawers that are generally kept closed, but allow access to the contents without having to step inside the refrigerated space. RSCs are typically used in catering applications and non-retail areas of supermarkets, butcheries, restaurants, hotels, cafes, professional kitchens and institutional facilities where they are used mainly for storage.

Latest news on commercial refrigeration

A consultation Regulation Impact Statement on Refrigerated Display Cabinets (RDCs) and Refrigerated Storage Cabinets (RSCs) has been released.

The consultation RIS examines issues raised by stakeholders during previous consultations and considers options to improve the current energy efficiency requirements for RDCs and RSCs.

Interested parties are asked to provide feedback on the consultation RIS. The closing date for any written submissions is 2 September 2016. For more information visit the consultation page.

Regulatory Requirements for Refrigerated Display Cabinets

When manufacturing or importing Refrigerated Display Cabinets (RDCs) in or into Australia, most equipment must comply with the requirements set out in the GEMS legislation. This includes the Minimum Energy Performance (MEPS) requirements set out in the GEMS determination.

 

Current regulation

On 1 October 2012, the Greenhouse and Energy Minimum Standards (GEMS) legislation came into effect, creating a national framework for appliance and equipment energy efficiency in Australia.  RDCs are one of the products that must be registered through an online database and meet a number of legal requirements before they can be sold in Australia or New Zealand. To find out the Minimum Energy Performance Standards (MEPS), check the relevant Australian GEMS determination or the New Zealand regulations.

 

Which MEPS do I need to comply with?

The MEPS for commercial refrigeration are set out as total energy consumption per total display area (TEC/TDA) in kWh/day/square meter for various unit types. The methods for measurement of total energy consumption are set out in the GEMS determination.

There is also a provision for “High Efficiency” refrigerated display cabinets which must meet more stringent MEPS levels to classify as ‘high efficiency’.

 

MEPS Levels

MEPS for regulated refrigerated display cabinets are set in the Greenhouse and Energy Minimum Standards (Refrigerated Display Cabinets) Determination 2012 (Determination).  The Determination calls up the levels specified in AS 1731.14-2003, and also sets the test methods by reference to AS 1731.14-2003 (which itself refers to other parts of AS 1731).

When measured in accordance with AS 1731.9 and AS 1731.12 the energy consumption of a remote or self-contained refrigerated cabinet shall not exceed that specified below (as applicable). For the purpose of testing compliance, tests are conducted under climate Class 3 conditions, with lighting and anti-sweat heaters running for the duration of test period, unless controlled by a time-clock, smart sensor or similar automatic device. Where night-covers are supplied as a permanent fixture of the cabinet, the test is conducted as described in AS 1731.9, Section 4. Reference should be made to the relevant parts of AS 1731 for detailed conditions and test methods.

High Efficiency Levels

High Efficiency levels for regulated refrigerated display cabinets are set in the Greenhouse and Energy Minimum Standards (Refrigerated Display Cabinets) Determination 2012 (Determination).  The Determination calls up the levels specified in AS 1731.14-2003, and also sets the test methods by reference to AS 1731.14-2003 (which itself refers to other parts of AS 1731).

A remote or self-contained refrigerated display cabinet may be designated ‘high efficiency only if its energy consumption, measured in accordance with AS 1731.9 and AS 1731.12 does not exceed that value specified below. For the purpose of testing compliance, tests are conducted under climate Class 3 conditions, with lighting and anti-sweat heaters running for the duration of test period, unless controlled by a time-clock, smart sensor or similar automatic device. Where night-covers are supplied as a permanent fixture of the cabinet, the test is conducted as described in AS 1731.9, Section 4. Reference should be made to the relevant parts of AS 1731 for detailed conditions and test methods.
