Specifies procedures for calculating the performance of factory-made residential, commercial and industrial, electrically driven, mechanical compression, single-package and split-system, ducted and non-ducted airconditioners for determining their compliance with minimum energy performance standard (MEPS) requirements specified in AS/NZS3823.2.

This Standard specifies procedures for calculating the performance of factory-made residential, commercial and industrial, electrically-driven, mechanical compression, single-package and split-system, ducted and non-ducted airconditioners and heat pumps employing air- and water-cooled condensers. This Standard covers equipment utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units controlled by a single thermostat/controller. This Standard covers equipment utilizing single, multiple and variable capacity components.NOTE: The method in this Standard includes a combination of measured component performance, equipment operating conditions and a mathematical model to determine the appliance performance.This Standard does not cover single circuit multiple compressor units.This Standard can be used to quantify the following values for cooling and heating:(a) Rated cooling capacity.(b) Rated heating capacity.(c) Energy efficiency ratio (EER).(d) Coefficient of performance (COP).This Standard does not apply to the rating of the following:(i) Water-source heat pumps.(ii) Multi-split airconditioners and heat pumps.(iii) Mobile appliances having a condenser exhaust duct.(iv) Unitary systems where there is a thermal interaction between the evaporator and condenser.
