1.1 General
1.1.1
This Document applies to unitary air conditioners and heat pumps that are
a) factory-made;
b) air-source and air-sink;
c) single-split systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems;
d) intended for space-heating and/or air-conditioning applications in buildings;
e) electrically driven, mechanical, vapour-compression-type systems; and
f) rated below 19.0 kW (65 000 Btu/h) heating or cooling at standard rating conditions, in accordance with Clause 5.2.
1.1.2
This Document does not apply to the following:
a) water-to-air and/or water units; and
b) heat recovery.
1.2 Unitary equipment
Unitary equipment within the scope of this Document is outlined in Table 1.
1.3 Terminology
In this Document, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with this Document; “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 this Document.
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.
1.4 Units of measurement
The values given in SI units are the units of record for the purposes of this Document. The values given in parentheses are for information and comparison only.
You may comment on any section of this document by clicking the “Submit Comment” link at the bottom of the relevant section.
