Item | For: | the energy consumption, or E24h, is equal to the amount: | as determined in accordance with: | at test room climate class: |
1 | an RDC | TEC | clauses 5 and 6 of ISO 23953‑2 | 3 |
2 | an ice cream freezer cabinet | TEC | clauses 6 and 7 of EN 16901 | 4 |
3 | a scooping cabinet | TEC | clauses 6 and 7 of EN 16838 | 4 |
4 | a light duty RSC, other than one covered by item 5 | E24h | clauses 5, 6 and 7 of EN 16825 | 3 |

13 Meaning of low sales volume and oversize
Note 1: For the purposes of this determination:
· models of ice cream freezer cabinets and scooping cabinets cannot be “low sales volume”; and
· models of ice cream freezer cabinets, scooping cabinets and RSCs cannot be “oversize”.
Note 2: A model of an RDC could be “low sales volume”, “oversize”, both, or neither. A model of an RSC might or might not be “low sales volume”.
Note 3: Under this determination, the annual energy consumption (AEC) and reference annual energy consumption (RAEC), and hence the energy efficiency index (EEI), of “low sales volume” and/or “oversize” RDCs, and of “low sales volume” RSCs, are calculated differently from other RDCs and RSCs (see sections 24 and 25). There is also an additional testing requirement for some “low sales volume” RDCs and RSCs (see section 27).
Note 4: For “low sales volume” RDCs and RSCs, the GEMS Regulator may request evidence of annual sales volumes under section 56 of the Act.
Note 5: A model of an RDC or an RSC may be registered on the basis that it is “low sales volume”. For such a model, annual sales must not exceed the threshold sales volumes specified in this section in order for the model to continue to be classified as “low sales volume”.
For an RDC, if at some time after registration, its annual sales exceed the threshold sales volumes, unless models of the product are also “oversize”, they will need to comply with the requirements of this determination that apply to RDCs generally.
For an RSC, if at some time after registration, its annual sales exceed the threshold sales volumes, models of the product will need to comply with the requirements of this determination that apply to RSCs generally.
If the models do not satisfy these general requirements, the GEMS Regulator might consider suspending or cancelling the model’s registration under Division 6 of Part 5 of the Act, or might consider commencing enforcement action.
In this determination:
low sales volume: an RDC or an RSC is low sales volume at a particular date:
(a) for an RDC or an RSC of a model that belongs to a family of models—if:
(i) the family of models is registered as a low sales volume family of models; and
(ii) no more than 25 units of the models that belong to the family of models are sold in the calendar year that includes that date; or
(b) for an RDC or an RSC of a model that that does not belong to a family of models—if:
(i) the model is registered as a low sales volume model; and
(ii) no more than 10 units of the model are sold in the calendar year that includes that date.
oversize: an RDC is oversize if, at the time of:
(a) if the model of the product was registered as a result of an application under section 41 of the Act—that application; or
(b) if the model of the product was registered as a result of a subsequent application under section 46 of the Act—that application;
as a result of its size, there is no testing laboratory:
(c) in which the RDC is able to be tested in accordance with ISO 23953‑2; and
(d) that has been approved by the National Association of Testing Authorities, Australia.
Note: Section 1 of Schedule 3 to this determination:
· sets out variations to ISO 23953‑2 that apply for the purposes of this determination; and
· provides for how ISO 23953‑2 applies in relation to low sales volume RSCs.

Specific energy consumption
(9) For subparagraph (2)(a)(i), the specific energy consumption of a refrigerated cabinet is equal to:

Note 1: For paragraph (a), section 1 of Schedule 3 to this determination sets out variations to ISO 23953‑2 that apply for the purposes of this determination.
Note 2: For paragraph (d), section 3 of Schedule 3 to this determination sets out variations to EN 16901 that apply for the purposes of this determination. Unlike RSCs, under EN 16901, the amount SEC for an ice cream freezer cabinet is calculated by dividing the energy consumption by the “equivalent volume” (rather than the net volume). The “equivalent volume” of an ice cream freezer cabinet is related to the cabinet’s net volume, but is normalised by factors that depend on the M‑package temperature class and test room climate class.
(10) For paragraph (9)(b), for an RSC, the amount SEC is given by the following formula:

where:
energy consumption is the cabinet’s energy consumption in kWh per 24 hours (see section 12).
net volume is the cabinet’s net volume in cubic metres (see section 5).
16 Product category
For section 29 of the Act, the products covered by this determination are category A products.

22 Definitions
(1) In this Part:
low-efficiency reference set: see reference low‑efficiency version.
reference low‑efficiency version of an RDC or an RSC means a hypothetical version of the cabinet in which the set of relevant components is replaced by a set of components (the low-efficiency reference set):
(a) each of which is of a kind listed in column 2 of the table to subsection (2); and

relevant component of a particular RDC or RSC means any component of the cabinet that is of a kind listed in column 1 of the table to subsection (2).
Note: A particular RDC or RSC will have only a single set of relevant components.
(2) For subsection (1), the table is:
| Column 1 Kinds of relevant components | Column 2 Kinds of low‑efficiency reference components |
1 | Fan motor | A shaded pole fan motor with an efficiency of 35% or lower |
2 | Lighting | Fluorescent lamps with B2 ballasts |

Note 2: For items 2 and 3 of the table, the product class could be any of product classes 3, 4, 9 or 10.
Note 3: For the product classes, see section 19 and Schedule 1.
24 Calculation of energy efficiency index or EEI
The energy efficiency index, EEI, of a refrigerated cabinet that is covered by this determination is calculated in accordance with the following formula:

where:
AEC is the refrigerated cabinet’s annual energy consumption, in kWh per year, and is calculated in accordance with section 25.
RAEC is the refrigerated cabinet’s reference annual energy consumption, in kWh per year, and is calculated in accordance with section 25.
Note: For refrigerated cabinets that are covered by this determination, other than low sales volume and/or oversize RDCs and low sales volume RSCs, the reference annual energy consumption is equal to the standard annual energy consumption, which represents the energy consumption of a standard cabinet of the relevant type.
For low sales volume and/or oversize RDCs and low sales volume RSCs, the reference annual energy consumption is equal to the base annual energy consumption, which reflects the energy consumption of a reference low‑efficiency version of a cabinet of the relevant type.
25 Calculation of annual energy consumption (AEC) and reference annual energy consumption (RAEC)
Note 1: Most calculations for the purposes of this section rely on calculation of the amount E24h (see section 12).
Note 2: For RDCs that are low sales volume and/or oversize, and for RSCs that are low sales volume, the calculations involve determination of various amounts on the basis of:
· the RDC or RSC with the actual components (the relevant components); and
· a hypothetical reference low‑efficiency version of the cabinet with a low‑efficiency reference set of components.
Note 3: In the case of low sales volume and/or oversize RDCs that are remote, the amounts are:
· the DEC (short for direct electrical energy consumption), which is a measure of the energy consumption of the electrical components of the RDC, and which excludes the energy consumption of the remote refrigeration system that runs the RDC (the REC); and
· the REC (short for refrigeration electrical energy consumption), which is a measure of the energy consumption of the refrigeration system that runs the RDC.
The sum of the DEC and the REC is a measure of the total energy consumption (the TEC) of the RDC.
Note 4: In the case of low sales volume and/or oversize RDCs that are integral, or low sales volume RSCs (which, in order to be covered by this determination, must be integral), only the amount TEC is determined (and not the separate amounts DEC and REC), and this amount is the total energy consumption of the RDC or RSC, including the integral refrigeration system.
