AS/NZS 3823.1.2:2012

Adopts ISO 13253:2011 wih modifications, to establish test methods for determining the capacity and efficiency ratings of ducted, air-cooled airconditioners and ducted air-to-air heat pumps. Residential, commercial and industrial single-package and split-system airconditioners and heat pumps are included.

This International Standard specifies the standard conditions for capacity and efficiency ratings of ducted, air-cooled air-conditioners and ducted air-to-air heat pumps. This International Standard is applicable to the test methods for determining the capacity and efficiency ratings. Residential, commercial, and industrial single-package and split-system air-conditioners and heat pumps are included. The equipment (taken to meanducted air-conditioners and/or ducted heat pumps) shall be factory-made and electrically driven, and shall use mechanical compression.This International Standard is applicable to equipment utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units controlled by a single thermostat/controller. This International Standard is applicable to equipment utilizing single-, multiple- and variable-capacity components.This International Standard is not applicable to the rating and testing of the following:a) water-source heat pumps or water-cooled air-conditioners;b) multi-split-system air-conditioners and air-to-air heat pumps (see ISO 15042 for testing of suchequipment);c) mobile (windowless) units having a condenser exhaust duct;d) individual assemblies not constituting a complete refrigeration system;e) equipment using the absorption refrigeration cycle;f) non-ducted equipment (see ISO 5151 for testing of such equipment).This International Standard does not cover the determination of seasonal efficiencies that can be required in some countries because they provide a better indication of efficiency under actual operating conditions.
