scope:

This Standard specifies the standard conditions for capacity and efficiency ratings of non-ducted portable air-cooled air conditioners and air-to-air heat pumps having a single exhaust duct. Such air conditioners and heat pumps may include an evaporatively cooled condenser cooled by air and the evaporation of-

(a) condensate collected from the evaporator;

(b) external supplementary water stored in a supplementary water tank; or

(c) both (a) and (b).

This Standard also specifies the test methods for determining the capacity and efficiency ratings.

The Standard applies to equipment that is factory-made, electrically driven and uses mechanical compression. This Standard is applicable to equipment utilizing one or more refrigeration systems.

This Standard is not applicable to the rating and testing of the following:

(i) Water-source heat pumps or water-cooled air conditioners.

(ii) Multi-split-system air conditioners and air-to-air heat pumps (see AS/NZS 3823.1.4 for the testing of such equipment).

(iii) Individual assemblies not constituting a complete refrigeration system.

(iv) Equipment using the absorption refrigeration cycle. (v) Ducted equipment (see AS/NZS 3823.1.2 for the testing of such equipment).

(vi) Non-ducted air conditioners and heat pumps, including dual-duct 'balanced type' portable air conditioners (see AS/NZS 3823.1.1 for the testing of such equipment).

(vii) Evaporative coolers or any other cooling systems that are not of the vapour compression type.

(viii) Dehumidifiers.

(ix) Spot coolers.
