Energy use – Calculation of AEER and ACOP(1)[(3)] The energy efficiency metric for products in all product classes, other

than those in product classes 14 and 15, for assessing compliance with subsection (1) is the Annual Coefficient of Performance (ACOP) for heating and the Annual Energy Efficiency Ratio (AEER) for cooling. Unless subject to the requirements of subsection (2), these values must be at 100% of rated capacity at the standard cooling full capacity test and the standard heating full capacity test. These values must be calculated in accordance with the following formula:

AEER∨ACOP= Cooling∨heating output (rated∨tested ) ×2000(Cooling∨heating power input ×2000 )+(Pia× 6.76)

Where:Cooling or heating output (rated or tested) is the output (capacity) value in kW for the standard cooling full capacity test or standard heating full capacity test.Cooling or heating power input (rated or tested) is the power input value in kW for the standard cooling full capacity test or standard heating full capacity test.2000 is the assumed hours of operation per year in cooling or heating mode.Pia is the Weighted Average Inactive Power Consumption as defined in Annex B of AS/NZS 3823.4.1 and AS/NZS 3823.4.2.6.76 is a factor that converts power (watts) to energy (kWh) for (8760 – 2000) hours per year.Note 1: The calculation of both rated and tested values for AEER and ACOP are

required to meet MEPSthe specified GEMS level requirements using this formula.

Note 2: Unless subject to the requirements of subsection (8), these tested and rated values must be at 100% of capacity at the rated standard cooling full capacity test and the rated standard heating full capacity test.

Note 13: Pia represents a single, annual, inactive power consumption figure that applies equally to both cooling and heating cycles. It can be measured/calculated once using Annex B of either AS/NZS 3823.4.1 or AS/NZS 3823.4.2.

Note 2: The energy efficiency metric for products in product classes 14 and 15 is the Energy Efficiency Ratio (EER) and the Coefficient of Performance (COP).

splits.

Conducting tests – specific requirements for unitary double duct units

[(33)] Wall mounted unitary double duct units must be tested as peruse the test procedures of AS/NZS 3823.1.1. They must be installed on the wall ofin the test chamber with the air intake and exhaust ducts as short as possible as per the manufacturer’s installation instructions.

[(34)] Except for the provisions of subsections (18) and (19), unitary double duct air conditioners must be tested to the mandatory test points of Table 1 in AS/NZS 3823.4.1 for cooling as per their product type (i.e. fixed speed, two-stage, multi-stage or variable speed). Suppliers may also elect to perform any of the optional tests.

[(35)] Except for the provisions of subsection (19), unitary double duct heat pumps <30 kW rated cooling capacity must be tested to the mandatory test points of Table 1 in AS/NZS 3823.4.2 for heating as per their product type (i.e. fixed speed, two-stage, multi-stage or variable speed). Suppliers may also elect to perform any of the optional tests.

[(36)] Except for the provisions of subsection (19), unitary double duct heat pumps ≥30 kW rated cooling capacity may test to the mandatory test points of Table 1 in AS/NZS 3823.4.2 for heating as per their product type (i.e. fixed speed, two-stage, multi-stage or variable speed).

If necessary, condensate containers must be modified to drain away excess condensate into a larger container in the test chamber before the volume that activates the cut-off switch is reached.Note 1: Some portable unitary double duct units may have an in-built hose to

facilitate the draining of condensate.


35

DRAFT ONLY

Note 2: Some portable unitary double duct units are designed to collect condensate and evaporate it on the condenser. This process should be allowed to occur during testing.

Note 3: The testing requirements of this subclause mirror the requirements for unitary single duct products as detailed in AS/NZS 3823.1.5.

(16)[(38)] Portable unitary double ducts might contain a supplementary water tank designed to provide additional water to an evaporatively cooled condenser. All cooling tests may be performed using this feature as per the manufacturer’s instructions provided they meet the requirements of subsection (27). Water added to a unit’s supplementary water tank must be 35°C ± 1°C.Note 1: Some portable unitary double ducts are fitted with a supplementary water

evaporation feature designed to provide additional water for the evaporatively cooled condenser and/or compressor. They generally require the user to fill the water tank and manually select an operational mode via the unit’s control panel or remote control that turns this function on. This operational mode may override other thermostat and fan settings and is designed to achieve higher cooling capacities and greater energy efficiency while this feature is active. When these units deactivate their supplementary water evaporation feature (for instance, when insufficient water is detected in the supplementary water tank), they may automatically revert to cooling without the aid of the supplementary water evaporation feature, or they may automatically switch off.

Note 2: This provision is not applicable to wall mounted unitary double duct products within product class 13.

Note 3: The testing requirements of this subsection mirror the requirements for unitary single duct products as detailed in AS/NZS 3823.1.5.

Note 4: AS/NZS 3823.4 uses the test procedures of AS/NZS 3823.1.1 for unitary double ducts.

(17)[(39)] Portable unitary double duct units within product class 14 that contain a supplementary water tank must have the duration of the tank determined during the standard cooling full capacity test. While the test setup and test conditions (T1) must be as per AS/NZS 3823.1.1, determining the duration of the supplementary water evaporation feature must be performed as per Appendix B of AS/NZS 3823.1.5.

(18)[(40)] If the calculated run-time of the supplementary water tank during the standard cooling full capacity test is ≥ 4 hours, the cooling tests of subsection (28) may use the supplementary water evaporation feature. A dual rating for the standard cooling full capacity must be used if the product reverts to air-to-air cooling once the supplementary water tank is empty. A single rating based on the supplementary water evaporation feature must be used if the product ceases operation once the supplementary water tank is empty. Compliance to subsection (1) (the MEPS levels) is based on using the supplementary water evaporation feature for those products that have a calculated tank run time of ≥4 hours. These requirements are summarised, below:

Schedule 1 Format of label

1. Colour and text details for the energy label (1) The example labels in Item 2 of the Schedule show the parts of the label

referred to within these instructions. (2) The example labels in Item 3 of this Schedule show the colour and text

requirements for the energy label. (3) The label must be printed on a white background using the following colours:

a. for red—Pantone Warm red;b. for yellow—Pantone 116; andc. for black—Pantone Black.

(4) The entire label, excluding the star ratings, must be in only one font, which can be any one of the following:

a. Gill Sans (preferred);b. Humanist 521; orc. Hammersmith.

(5) The star ratings must be in the font Meta OT. (6) For each relevant heating and cooling function, a star rating must be shown in

numerals in a star, positioned as detailed below. There must be a set of such ratings for each geographical region. Further details on the rating star and star band are provided in Items 5 and 6. A product that does not provide either a cooling or heating service must not place a rating star on the star band for that service. See Item 8 labels (i) and (ii) for examples.

a. The cooling function star rating must be shown in a blue star within a square box with black outline; this is the ‘rating star’. A rating of 0 must be shown in a grey star. A rating of 0.5 must be shown in a star whose left half is blue and right half grey.

b. The heating function rating star must be shown as a red star within a square box with black outline. A rating of 0 must be shown in a grey star. A rating of 0.5 must be shown in a star whose left half is red and right half grey.

c. The rating star must be vertically centred on the centre of the relevant star in the star band. For example, if the rating is ‘4 stars’ then the rating star aligns with the fourth star in the band; this obscures the fourth star, and some of the third. Rating stars from 0 to 1 are placed in the same location; the centre of the rating star must sit on the centre of the first star in the star band. For a rating involving a half star, the rating star must bisect the gap between the stars that bracket the value.

d. The coloured band for the star rating must extend to the edge of the rating star box.

(7) The brand and model of the product must: a. be inserted where indicated by ‘a’ in Item 2 base label (i);b. be complete and concise;
