Water-Source Heat Pumps - Testing and Rating for Performance - Part 2: Water-to-Water and Brine-to-Water Heat Pumps
Scope:
1.1 This part of ISO 13256 establishes performance testing and rating criteria for factory-made residential, commercial and industrial, electrically-driven, mechanical-compression type, water-to-water and brine-to-water heat pumps. The requirements for testing and rating contained in this part of ISO 13256 are based on the use of matched assemblies.
1.2 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.
1.3 This part of ISO 13256 does not apply to the testing and rating of individural assemblies for separtate use or to units having two or more indoor section connected to a single outdoor section. It does not apply to heat pumps covered in ISO 5151, ISO 13253 or ISO 13256-1.
NOTE - For the purpose of the remaining clauses, the terms "equipment" or "heat pumps" may be used to mean "water-to-water heat pumps" or "brine-to-water heat pumps" and the term "liquid" refers to either "water" or "brine".
