SCHEDULE 3

PART C

CALCULATION OF ENERGY RATINGS, EFFICIENCY RATINGS AND STAR

RATINGS

Calculation 1

Class 1, 2, 3 of Domestic Appliances

The energy rating is to be derived from formula (1) below, and the result rounded off to one decimal place. The formula includes the following adjustment factors:

(i)            Defrost Energy Adjustment Factors, a and b

These factors are applied to compensate for the fact that defrost energy is included in the AS2575.2 test results for refrigerators incorporating frost free freezer compartments and auto defrost (frost free and cyclic defrost) fresh food compartments, whereas defrost energy is not included in the test results for refrigerators incorporating manual defrost freezer or fresh food compartments.

(ii)           Freezer Volume Adjustment Factor, d

This factor is applied to freezer volume, so that total refrigerator gross volume can be expressed in terms of a fresh food compartment equivalent. The application of this adjustment factor, recognises the different tasks performed by the fresh food and freezer compartments, and weights the freezer volume accordingly.

The Energy Rating Formula is—

Energy rating = W + (Vf × a) + (Vff × b) (1)

(Wh/litre/24 hours) Vff + (Vf × d)

Where W = Total energy consumption as determined in accordance with Appendix B of

AS2575.2 testing in Watt hours per 24 hours (Wh/24 hrs).

Vf	=	Frozen food compartment rated gross volume as per AS1430.
Vff	=	Fresh food compartment rated gross volume as per AS1430.
a	=	Freezer defrost energy adjustment factor. (See Table 1 below).
b	=	Fresh food compartment energy adjustment factor. (See Table below).
d	=	Freezer Volume adjustment factor = 32° - Tav
(See Table 1 below). 32° - Tff
Tav	=	Freezer or other "specialized" food compartment temperature in degrees celsius in accordance with AS2575.2.
Tff	=	Fresh food compartment temperature in degrees celsius.

Adjustment factors for the various AS1430 classes of refrigerators and freezers are presented in Table 1.

Table 1—Adjustment Factors

AS 1430 a b Tav Tff d

Class (Wh/l/24hr) (Wh/l/24hr) (°C) (°C)

1	0	0	N/A	3	0
2	0	0.1	-2	3	1.2
3	0	0.15	-9	3	1.4

4	0.2	0	-15	3	1.6
5	0	0	-15	3	1.6
6	0.2	0	-15	N/A	1.6
7	0	0	-15	N/A	1.6

Example—Class 4 Refrigerator/Freezer

W	= 1020 kWh/yr = 2795 Wh/24hr
Vf	= 94 l
Vff	= 240 l
a	= 0.2 Wh/l/24hr
b	= 0
d	= 1.6
Vf × a	= 94 × 0.2 = 18.8 Wh/24hr
Vff × b	= 240 × 0 = 0
Vf × d	= 94 × 1.6 = 150.4 l

Energy Rating = W + (Vf × a) + (Vff × b)

Vff + (Vf × d)

= 2 795 + 18.8 + 0

240 + 150.4

= 7.2 Wh/l/24hr

METHOD OF REPRESENTING ENERGY RATING ON LABELS

(i)           The Continuous Rating Band

The digits (1 to 5) shown on the rating component of the label do not represent directly the Wh/litre/24 hours figure calculated from the formula in appendix 1 of the Australian Standard 2575.2. When graphing the Wh/litre/24 hours figure in a continuous manner, the following arithmetic scale is to be used:

Number Shown on Dial—Equivalent Wh/litre/24 hours

1 = 10 Wh/l/24hrs

2 = 8.5

3 = 7.0

4 = 5.5

5 = 4.0

6* = 2.5

*(Although 6 is not actually shown on the dial, its position is the top of the box containing the "Y" in

ENERGY).

Results rounded to the nearest one decimal place are graphed by arithmetic interpolation between the

figures.

(ii)          Allocation of Stars

Star allocation is to be based on the adjusted Wh/litre/day energy consumption as calculated from formula 1 in this schedule and made in the following way:

less than or equal to

6 Stars

2.5 Wh/litre/day—

spaced evenly across the dial

2.6 to 4.0 Wh/litre/day—

5 Stars

placed evenly up to the pointer 5

4.1 to 5.5 Wh/litre/day—

4 Stars

placed evenly up to the pointer 4

5.6 to 7.0 Wh/litre/day—

3 Stars

placed evenly up to the pointer 3

7.1 to 8.5 Wh/litre/day—

2 Stars

placed evenly up to the pointer 2

Greater than or equal to

1 Star

8.6 Wh/litre/day—

placed evenly up to the pointer 1

Note that although the red band is a continuous scale, stars only appear once the threshold Wh/litre/day ratings are reached.

Class 5 of Domestic Appliances: Dishwashers

The dishwasher must be tested in accordance with AS 2007; at least 3 test runs must be conducted and the total energy consumption of each run averaged.

The result Et = Average Test Energy

Energy consumption rate per year is based on one operation of the appliance per day.

Ea = Energy consumption rate = Et × 365

Energy consumption rate per place setting, (EP), is thus:

EP = Ea/Np

where Np is the number of place settings.

The number of stars the determined energy efficiency rating represents is as follows:

Energy Efficiency Rating = (EP × (-0.1)) + 8

Note that the red band on the label extends to 4.58. Only the four complete stars are shown.

Calculation 4

Class 6 of Domestic Appliances: Clothes Dryers

The clothes dryer must be tested in accordance with AS 2442.

A ENERGY EFFICIENCY RATING

The energy efficiency rating is represented on the label as a continuous red band with a minimum energy efficiency rating of one.

Energy efficiency rating = 8(1.5 - Ex) [this should read Es]

Where Es is the specific energy consumption of that rotary clothes dryer.

Specific energy consumption Es = Ff(Et/mr) in kWh/kg of water removed.

where	Et	=	total energy consumption at the end of the drying cycle in kilowatt hours.
mr	=	mass of moisture removed from clothes in kilograms.
Ff	=	the field use factor. It accounts for the over drying of clothes and is equal to 1.1 for timer/manual controlled clothes dryers or 1.0 for automatic dryness controlled clothes dryers.

(Note: Et and mr used above are the average of the total energy consumption and mass of moisture

removed, calculated in accordance with Schedule 4.)

Example: A 5 kg clothes dryer controlled by a timer consumes a total of 4.21 kWh of electrical energy and removes 4.41 kg of water.

Es	=	Ff(Et/mr)
=	1.1 (4.21/4.41)
=	1.05 kWh/kg of water removed.

Energy efficiency rating

= 8(1.5 - Es)

= 8(1.5 - 1.05)

= 3.60

With the example given in section A, the red band extends to 3.60 with three complete stars being

shown.

C ENERGY CONSUMPTION RATE

The energy consumption rate represents the energy consumed by the clothes dryer per year (150 full

loads per year). It appears in the box in the centre of the label.

Energy consumption rate = 150 × Ff × Et in kWh per year

Where Et is the total consumption at the end of the drying cycle.

The example for the clothes dryer shown before gives:

Energy consumption rate	=	150 × 1.1 × Et
=	150 × 1.1 × 4.21

= 694 kWh per year

Calculation 5

Class 7 of Domestic Appliances: Washing Machines

The washing machine must be tested in accordance with AS 2040.

A COMPARATIVE ENERGY CONSUMPTION RATE

The comparative energy consumption rate is determined by multiplying the total energy consumption (ET) by 365. The total energy consumption is the addition of the following components:

Ee =

the electrical energy consumption, as reported in the test report, in kWh

Eh =

the energy equivalent of the imported hot water where applicable, and calculated in

accordance with the following formula:

Eh = Qh (th - 20)/860 in kWh

where Qh is the cycle’s hot water consumption in litres and th is the hot water supply

temperature in °C.

Ec =

the energy equivalent of the imported cold water, where the water supply temperature

differs from 20°C and calculated in accordance with the following formula:

Ec = Qc (tc - 20)/860 in kWh

where Qc is the cycles cold water consumption in litres and tc the cold water supply

temperature in °C.

The total energy consumption formula is:

ET = Ee + Eh + Ec in kWh.

= Ee + Qh (th - 20) + Qc (tc - 20)

The Comparative Energy Consumption is equal to:

ET × 365

where ET is the total energy consumption of that clothes washing machine in kWh.

B	ENERGY EFFICIENCY RATING
The energy efficiency rating is calculated from the clothes washing machine specific energy consumption
(es).
The specific energy consumption (es) is equal to:

es = (ET + Em)/md in kWh/kg.

where ET = total energy consumption is calculated in Part Q, in kWh.

md is the mass of the bone dry test load in kg.

Em =

the energy equivalent of moisture not removed from the test load at the end of the final spin

dry cycle and calculated in accordance with the formula below:

Em = Fs Ms in kWh

where Fs = 0.21 and is an empirical factor accounting for the energy required to remove the remaining moisture by evaporation and the annual use of clothes drying machines, in kWh/kg.

Ms is the remaining mass of water in the test load after the end of the final spin dry cycle in kg.

The energy efficiency rating is represented by the red band in the dial part of the energy rating label.

energy efficiency rating = 6.9 (1-es)

where es is the specific energy consumption as calculated above in kWh/kg.

Where a clothes washing machine also incorporates a cycle to dry the clothes by evaporation and this cycle can be chosen without the need to remove the clothes, then the specific energy consumption will be multiplied by a factor of:

(Rated capacity of washing section)

(Rated capacity of clothes drying section)

This modified specific energy consumption will be used for all calculations of energy efficiency rating

and star rating.

SCHEDULE 4

Methods, Test Reports and Minimum Performance Requirements: Class 6 of

Domestic Appliances: Clothes Dryers

METHODS FOR DETERMINATION OF MOISTURE REMOVAL AND ENERGY CONSUMPTION

This part of the schedule sets out three methods for the determination of moisture removal and energy consumption which replace Appendix B and C of AS 2442. These methods are consistent with those stated in that standard except for the following primary differences:

(1)

the moisture in the load is required to be reduced to 6 ± 1 per cent and;

(2)

rotary clothes dryers controlled by automatic dryness controls will be operated until the drying

cycle automatically terminates.

For rotary clothes dryers controlled by timers the following methods may be used for the determination of moisture removal and energy consumption:

(1)	method A;
or
(2)	method B, if platform scales of sufficient accuracy are available (± 10g).

For rotary clothes dryers controlled by automatic dryness controls, method C will be used for the determination of moisture removal and energy consumption.

METHOD A

Determination of Moisture Removal and Energy Consumption

A1 SCOPE.

This is the preferred method for evaluating the performance of a household rotary clothes dryer in removing moisture from a specified damp load to reach a specified dryness. In particular it sets out a method of calculating the specific energy consumption (Es) in kilowatt hours per kilogram of moisture removed.

(Note: Where platform scales of sufficient accuracy are available some test laboratories may find it more

convenient to use the test method B as an alternative to that described in paragraph A4.2).

A2 EQUIPMENT.

A2.1 Description.

The following equipment is required:

(a)	scales or balance;
(b)	platform scale which can be locked out of balance (optional) (see paragraph A4.2.2);
(c)	stabilised voltage supply, instruments for measuring elapsed time, temperature, relative humidity and electrical instruments including a watt hour meter.

A2.2 Accuracy of instruments.

Measuring instruments must have an accuracy within the limits stated below:

Instrument	Accuracy
Mass

(a)	scales or balance	± 5g
(b)	platform scales	± 10g

wet and dry bulb temperature ± 0.5°C

Electrical measurements—as specified for Class 0.5 instruments in AS 1024 or AS 1042.

A3 METHOD OF LOADING.

A standard damp load, prepared in accordance with paragraph A3 or Appendix A of the specifications, must be loaded into the dryer in accordance with the manufacturer’s instructions. If no instructions are given, the garments must be shaken individually and loaded loosely.

A4 PROCEDURE.

A4.1 Operation of dryer.

A4.1.1 Dryers controlled by timers.

For dryers controlled by timers the dryer must be operated at maximum temperature setting, with the timer set at maximum time until the moisture in the load has been reduced to 6 ± 1 per cent.

The timer may be reset, if necessary, to allow the required moisture content to be achieved; the number

of resets must be recorded. The dryer must not be operated into any cool-down period.

A4.2 Preferred test method (method B is an alternative method).

A4.2.1 Principle of test method.

The amount of energy required to reduce the standard damp load to 6 ± 1 per cent moisture content is determined by means of a trial run or from experience.

Test runs are then carried out, terminating when the energy determined in the trial run has been consumed and the percentage moisture content of the load is then calculated.

A total of three runs is required (not necessarily consecutive) in which the final moisture content is determined as being within 6 ± 1 per cent.

A4.2.2 Trial run.

A suitable procedure for a trial run is as follows:

(a)	place the dryer on a platform scale with all power and recording leads connected and record the mass of the dryer;
(b)	load the dryer in accordance with paragraph A3;
(c)	record the combined mass of the dryer and the clothes load, the initial watt hour meter reading (in kilowatt hours) and the time, lock the platform scale and start the dryer;
(d)	stop the dryer twice at about 30 minute intervals, unlock the scale, quickly record the combined mass, the watt hour meter reading and the time, then restart the dryer;
(e)	calculate the percentage moisture content of the load for these two readings and plot them on a graph against energy consumption (a typical graph is illustrated in fig. A1, points A and B being the readings taken—extrapolate the curve AB to obtain a figure of 6 per cent moisture content (point C on fig. A1) and estimate the amount of energy required to obtain this, e.g. quantity X on fig. A1);
(f)	stop the dryer finally when the energy figure estimated from the graph is reached, e.g. quantity X on fig. A1 and record the combined mass, the watt hour meter reading and the time;

(Note: Termination on a time basis is also permissible (see paragraph A4.2.3(c).))

(g)	remove the load from the dryer and confirm the net mass of the load on the scale or balance to within 5g;
(h)	calculate the percentage moisture content of the load and plot on the graph, e.g. point D of fig. A1. If the value obtained is outside 6 ± 1 per cent, extrapolate the curve ABD in order to obtain the estimated value of energy consumption to give a moisture content of 6 per cent, e.g. point E and quantity Y on fig. A1.

A4.2.3 Test run.

For the test run the procedure, which is repeated three times, must be as follows:

(a)

with the dryer at room temperature load in accordance with paragraph A3;

(b)

record the mass of the clothes load, the initial watt hour meter reading and the time and start the dryer;

(c)

stop the dryer when the energy consumption determined in step (h) of paragraph A4.2.2 has been reached, e.g. quantity Y on fig. A1 and record the watt hour meter reading and the time;

(Note: Alternatively, an energy consumption or a drying time determined from experience may be

used to terminate the test run, provided that the final moisture content is within 6 ± 1 per cent.)

(d)

remove the load from the dryer and determine with minimum delay the net mass of the load on the balance or scales to within 5 g;

(e)

calculate the percentage moisture content of the load. (If in any run the moisture content is outside 6 ± 1 per cent, the run must be rejected.)

A5 DATA RECORDING AND ANALYSIS.

A5.1 Recording data.

The following data must be recorded for each run:

(a)	mass of clothes load in bone dry condition (md) in kilograms;
(b)	mass of damp clothes load (mw) in kilograms;
(c)	mass of clothes load at the end of drying cycle (mf) in kilograms;
(d)	total energy consumption at the end of drying cycle (Et) in kilowatt hours;
(e)	the drying time duration (T);
(f)	laboratory temperature, in degrees Celsius, and relative humidity, per cent;
(g)	number of resets of timer to achieve required moisture content.

A5.2 Calculations for each test run.

The data in table A1 must be calculated for each test run made in accordance with paragraph A4.2.3.

A5.3 Calculations for three test runs.

The average values for the three test runs must be calculated for:

(a)	the specific energy consumption (Es), in kilowatt hours per kilogram of moisture removed;
(b)	the final percentage moisture content of the load (Mc).

METHOD B

Alternative Method for Determination of Moisture Removal

and Energy Consumption

B1 SCOPE.

This section sets out an alternative method to that given in paragraph A4.2 of section A for determination of moisture removal and energy consumption of a rotary clothes dryer. It may be more convenient for some test laboratories, depending on the availability of platform scales of sufficient accuracy (at least ± 10g).

The principal variations from the method A are as follows:

(a)	the dryer is subject to brief stoppages during the drying cycle;
(b)	the exhaust air temperature is monitored;
(c)	the final mass of the clothes load is not determined by separate weighing.

B2 TRIAL RUN.

A trial run is conducted as follows:

(a)	place the dryer on the platform scale, with all power and recording leads suitably connected;
(b)	determine the mass of the empty dryer and to this value add 106 per cent of the value of the mass of the test load in a bone-dry condition (see A2.4 in A of the specifications)—record this total mass (ms1);
(c)	prepare and load a standard damp load into the dryer in accordance with paragraph A3 of method A;
(d)	record the total mass (ms2) of the dryer plus damp load, the initial watt hour meter reading (in kilowatt hours to the nearest 0.001 kW.h) and the time;
(e)	lock the platform scale, start the dryer and record the exhaust air temperature against elapsed drying time;

(Note: It is advantageous to record the exhaust air temperature using a chart recorder with a chart speed of approximately 75 mm/h. If a chart recorder is not used the temperature should be plotted against elapsed drying time as shown in fig. B3.)

(f) the exhaust air temperature graph will start to level off after about 10 min.—during the period that the temperature reading is reasonably level, stop the dryer twice, unlock the platform scale and record the mass of dryer and load (ms3), kilowatt hour meter reading and times;

(Note: It is important to keep the time taken for these readings to a minimum.)

(g)	when the exhaust air temperature begins to rise more rapidly, stop the machine at 5 minute intervals, unlock the platform scale and record mass, kilowatt hours and time until the mass of the dryer plus the load is equal to or less than the mass obtained in (b), i.e. ms1;
(h)	plot the mass of dryer and load, in kilograms, against time, in minutes, as shown on fig. B3 and interpolate from the curve the actual time required to dry the load to a moisture content of 6 per cent;

(i) plot the reading on the energy meter in kilowatt hours, against time, in minutes as shown in fig. B4—from the actual time determined in step(h) determine the actual energy consumption required to dry the load to a moisture content of 6 per cent.

B3 TEST RUN.

The procedure for the test run must be as follows:

(a)	allow the dryer to cool to ambient temperature and repeat steps (b) to (e) of paragraph B2;
(b)	when the exhaust air temperature begins to rise rapidly, near the end of the cycle, repeat step (g) of paragraph B2;
(c)	using the graphs plotted in the trial run, paragraph B2, steps (h) and (i), determine the actual time (T) and energy consumption (Et) required to dry the load to a moisture content of 6 per cent;
(d)	repeat steps (a), (b) and (c) twice.

METHOD C

Determination of Moisture Removal and Energy Consumption for Rotary Clothes

Dryers Controlled by Automatic Dryness Controls

C1 SCOPE.

This method must be used for the determination of moisture removal and energy consumption of rotary clothes dryers which are automatically terminated by a controller that is other than time based.

The principal variations from method A and method B are as follows:

(a)	the dryer is required to be operated until the drying cycle automatically terminates;
and
(b)	graphical determination of energy consumption is not required.

C2 EQUIPMENT.

As described in paragraph A2 of method A.

C3 METHOD OF LOADING.

As described in paragraph A3 of method A.

C4 PROCEDURE.

C4.1 Operation of dryer

The dryer must be operated at the maximum temperature setting until the automatic dryness control terminates the drying cycle. If the automatic dryness control allows the user to select degrees of dryness, then the automatic dryness control is to be set at a level recommended by the manufacturer/importer so that the moisture content of the standard damp load is reduced to at least 7 per cent.

The dryer must not be operated into any cool-down period.

C4.2 Test method

Method A or method B may be chosen to determine the moisture removed and energy consumption of the rotary clothes dryer, however, no trial run or stopping of the dryer is required. Hence, there is no need to plot graphs as described in both methods.

Three test runs are then carried out, terminating when the drying cycle automatically terminates and calculating the moisture content of the load.

If 7 per cent moisture level cannot be achieved, then the automatic dryness control must be manually overridden and tested as a time terminated machine using method A or method B. In this case, the determined energy consumption must be calculated according to the procedure outlined in schedule 3 for time terminated machines (i.e. the field use factor Ff = 1.1).

C5 DATA RECORDING AND ANALYSIS.

The data recorded and calculations undertaken are to be the same as paragraph A5 of method A. However, the times recorded and calculated to dry the standard load from 100 per cent to the final moisture content will replace 6 per cent moisture content in paragraph A5.1 (e).
