BCA Part J5.11 Unitary air-conditioning equipment
Unitary air-conditioning equipment including packaged air-conditioners, split systems, and variable refrigerant flow systems must comply with MEPS and for a capacity greater than or equal to 65 kWr—
(a) where water cooled, have a minimum energy efficiency ratio of 4.0 Wr / Winput power for cooling when tested in accordance with AS/NZS 3823.1.2 at test condition T1, where input power includes both compressor and fan input power; or
(b) where air cooled, have a minimum energy efficiency ratio of 2.9 Wr / Winput power for cooling when tested in accordance with AS/NZS 3823.1.2 at test condition T1, where input power includes both compressor and fan input power.
[A unitary air-conditioner is a modular factory assembled air-conditioning unit. These units are self-contained and include within the unit all the components for heating and/or cooling such as fans, controls, a refrigeration system, heating coil and sometimes the heater. Split systems, packaged air-conditioners, variable refrigerant flow and variable refrigerant volume air-conditioners are all types of unitary air-conditioners.
J5.11(a) states that unitary air-conditioning equipment with a capacity of less than 65 kWr must have a minimum energy efficiency ratio when cooling complying with MEPS.
J5.11(b)(i) specifies the efficiency required for water-cooled packaged air-conditioning equipment.
J5.11(b)(ii) specifies the efficiency required for air-cooled packaged air-conditioning equipment.
AS/NZS 3823.1.2 has various test conditions so this clause requires the equipment to be tested at condition T1. This standard covers the performance of electrical appliances – air-conditioners and heat pumps, ducted air-conditioners and air-to-air heat pumps – testing and rating for performance.]
