20  Meaning of ACOP, AEER, COP and EER
 (1) In this Determination:
Annual Coefficient of Performance or ACOP means the measure of the energy efficiency of the heating function of air conditioners and incorporates Weighted Average Inactive Power Consumption (Pia).
Annual Energy Efficiency Ratio or AEER means the measure of the energy efficiency of the cooling function of air conditioners and incorporates Weighted Average Inactive Power Consumption (Pia).
Coefficient of Performance or COP means a ratio of the standard heating full capacity to the power input to the product (watts/watts).
Energy Efficiency Ratio or EER means the ratio of the standard cooling full capacity to the power input to the product (watts/watts).
Calculation of ACOP and AEER
 (2) For this Determination, a product's ACOP and AEER are calculated in accordance with the following formula:
  where:
capacity is:
 (a) in relation to the product's ACOP—the product's standard heating full capacity or standard heating part‑load capacity, as appropriate, in kW; and
 (b) in relation to the product's AEER—the product's standard cooling full capacity or standard cooling part‑load capacity, as appropriate, in kW.
power input is the product's power input, in kW, when determining the relevant capacity.
Pia is the Weighted Average Inactive Power Consumption, in watts, as defined in Annex B of AS/NZS 3823.4.1:2014 and AS/NZS 3823.4.2:2014.
Note 1: Pia represents a single, weighted, average, 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 3823.4.1:2014 or AS/NZS 3823.4.2:2014. The product of the amount Pia and the number of hours of inactive mode, Hia, as given by AS/NZS 3823.4.1:2014 or AS/NZS 3823.4.2:2014, is equal to the annual inactive energy consumption CIAE, as used in subsections 30(1) and (2).
Note 2: The number 2000 represents the assumed hours of operation per year in cooling or heating mode.
Note 3: The number 6.76 is a factor that converts power (watts) to energy (kWh) for 6760 (that is, 8760 – 2000) hours per year.
