Description

This international Standard 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.

Part 2 of the Standard covers heating and cooling systems which are generally referred to as “water-source heat pumps.” These systems generally include an indoor coil with air-moving means, a compressor, and a refrigerant-to water or refrigerant-to-brine heat exchanger. A system may provide both heating and cooling, cooling-only, or heating-only functions.

Scope

Part 2 of the Standard 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 the standard are based on the use of matched assemblies.

Equipment designed for rating at one application under this part of the Standard may not be suitable for rating at all
applications covered in this part of ISO 13256.
