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-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.

1.2 Equipment designed for rating at one liquid temperature range under this part of ISO 13256 may not be suitable at all liquid temperature ranges covered in this part of ISO 13256.

1.3 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.

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 may be designed for rating at one or several source and load side temperature conditions described in this part of ISO 13256.

1.3 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 13256-1.

ISO 13253:2017 specifies performance testing, the standard conditions and the test methods for determining the capacity and efficiency ratings of air-cooled, air-conditioners and air-to-air heat pumps. ISO 13253:2017 is applicable to the following equipment: - ducted air-cooled air conditioners and ducted air to air heat pumps. ISO 13253:2017 is limited to - residential, commercial and industrial single-package, and split-system air conditioners and heat pumps, - factory-made, electrically driven and use mechanical compression, - utilizing single, multiple and variable capacity components, and - multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller. The requirements of testing and rating contained in this document are based on the use of matched assemblies. ISO 13253:2017 is not applicable to the rating and testing of the following: a) water-source heat pumps or water-cooled air-conditioners; b) multi-split-system air-conditioners and air-to-air heat pumps (see ISO 15042 for testing of such equipment); c) mobile (windowless) units having a condenser exhaust duct; d) individual assemblies not constituting a complete refrigeration system; e) equipment using the absorption refrigeration cycle; f) non-ducted equipment (see ISO 5151 for testing of such equipment); g) ducted air conditioners and/or ducted heat pumps, rated at less than 8 kW and intended to operate at external static pressures of less than 25 Pa, controlled by a single thermostat/controller (refer to ISO 5151). ISO 13253:2017 does not cover the determination of seasonal efficiencies, which can be required in some countries because they provide a better indication of efficiency under actual operating conditions. NOTE Throughout this document, the terms "equipment" and "systems" mean "air-conditioners" and/or & ...

This International Standard specifies performance testing, the standard conditions and the test methods for

determining the capacity and efficiency ratings of air-cooled air-conditioners and air-to-air heat pumps.

This International Standard is applicable to the following equipment:

― basic multi-split systems, modular multi-split systems and modular heat recovery multi-split systems.

These multi-split systems include air-to-air systems with non-ducted and/or ducted indoor units with

integral fans and indoor units supplied without fans.

This International Standard is limited to:

― residential, commercial and industrial split-system air conditioners and heat pumps ; and

― factory-made, electrically driven and use mechanical compression; and

― single- and multiple-circuit split-systems which utilize one or more compressors with no more than two

steps of control of the outdoor unit.

or

― split-systems with a single refrigeration circuit which utilize one or more variable-speed compressors

or alternative compressor combinations for varying the capacity of the system by three or more steps.

These split-systems are designed to operate with a combination of one or more outdoor units and two or more

indoor units designed for individual operation, and such modular systems that are capable of transferring

recovered heat from one or more indoor units to other units in the same system.

The requirements of testing and rating contained in this International Standard are based on the use of

matched assemblies.

This International Standard is not applicable to the rating and testing of the following:

a) water-cooled or water source equipment;

b) mobile (single-duct) units having a condenser exhaust duct;

c) individual assemblies not constituting a complete refrigeration system;

d) equipment using the absorption refrigeration cycle.

e) ducted air conditioners and/or ducted heat pumps, rated at less than 8 kW and intended to operate at

external static pressures of less than 25 Pa, controlled by a single thermostat/controller (refer to ISO 5151);

f) multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller (refer to ISO 5151 or ISO 13253).

This International Standard does not cover the determination of seasonal efficiencies or seasonal part-load performances, which can be required in some countries because they provide a better indication of efficiency under actual operating conditions.

NOTE: Throughout this International Standard, the terms “equipment” and “systems” mean “multi-split air-conditioners” and/or “multi-split heat pumps”.

This International Standard is applicable to the following equipment:

― non-ducted air-cooled air conditioners and non-ducted air to air heat pumps; or

― ducted air conditioners and/or ducted heat pumps rated at less than 8 kW and intended to operate at an external static pressure of less than 25 Pa.

This International Standard is limited to:

― residential, commercial and industrial single-package and split-system air conditioners and heat

pumps ; and

― factory-made, electrically driven and use mechanical compression ; and

― utilizing single, multiple and variable capacity components ; and

― multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller.

The requirements of testing and rating contained in this International Standard are based on the use of matched assemblies.

This International Standard is not applicable to the rating and testing of the following:

a) water-source heat pumps or water cooled air conditioners;

b) multi-split-system air conditioners and air-to-air heat pumps (see ISO 15042 for the testing of such equipment);

c) mobile (windowless) units having a condenser exhaust duct;

d) individual assemblies not constituting a complete refrigeration system;

e) equipment using the absorption refrigeration cycle;

f) ducted equipment except for those specified in this clause (see ISO 13253 for the testing of such equipment).

This International Standard does not cover the determination of seasonal efficiencies, which can be required in some countries because they provide a better indication of efficiency under actual operating conditions.

NOTE: Throughout this International Standard, the terms “equipment” and “systems” mean “air-conditioners” and/or “heat pumps”.
