Scope

1.1 General

1.1.1 This Standard applies to unitary air conditioners and heat pumps that are
a) factory-made;
b) air-source and/or air-sink;
c) split-system matching assemblies (including mini-split and multi-split) or single package;
d) of the type classified in Clause 1.2;
e) intended for air-conditioning and space-heating applications in buildings;
f) electrically driven, mechanical, vapour-compression-type systems; and
g) rated below 19.0 kW (65 000 Btu/h) heating or cooling at standard rating conditions, in accordance with Clause 5.2.

Note: This includes space constrained single-package or split-system and small-duct high-velocity central air conditioners and heat pumps matching assemblies of the type classified in Clause 1.2 and intended for air conditioning and space-heating applications in buildings.

1.1.2 This Standard does not apply to the following:
a) burner-assisted air-source heat pumps;
b) air-source/air-sink multi-function heat pump systems;
c) integrated vapour-compression-type heat pump systems;
d) "Direct Expansion Dedicated Outdoor Air Systems" (DX-DOAS); and
e) water-cooled and evaporatively-cooled unitary air conditioners and heat pumps.
