General

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.

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.

Terminology

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

Units of measurement

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
