This part of ISO 13256 establishes performance testing and
rating criteria for factorymade residential, commercial and
industrial, electrically-driven, mechanical-compression type,
water-to-air and brine-to-air heat pumps. The requirements for
testing and rating contained in this part of ISO 13256 are based on
the use of matched assemblies.
Equipment designed for rating at one application under this part
of ISO 13256 may not be suitable at all applications covered in
this part of ISO 13256.
This part of ISO 13256 does not apply to the testing and rating
of individual assemblies for separate use, nor to the testing and
rating of heat pumps covered in ISO 5151, ISO 13253 or ISO
13256-2.
NOTE — For the purpose of the remaining clauses, the terms
"equipment" or "heat pumps" may be used to mean "water-to-air heat
pumps" or "brine-to-air heat pumps" and the term "liquid" refers to
either "water" or "brine".
NOTE: Airconditioners with water cooled condensers have been
excluded from AS/NZS 3823.1.1 and AS/NZS 3823.1.2 and are covered
under the requirements of this Standard.
This does not cover the determination of seasonal efficiencies
which may be required in some countries.
