Variable refrigerant flow air-to-air conditioners and air-to-air heat pumps — Testing and calculating methods for seasonal performance factors and energy performance mapping approach
Description
This document specifies:
- the test conditions and test methods for determining capacity and efficiency ratings;
- calculation methods for seasonal performance.
This applies to factory made, electric mains operated, variable refrigerant flow air-cooled air conditioners and air-to-air heat pumps with a rated capacity above 12 kW for cooling or for heating if the product has no cooling function.
In this document, “heat pumps” means “air-to-air heat pumps” and “air conditioners” means “air-cooled air conditioners”.
This document establishes a method for determining global variable refrigerant flow (VRF) performance with annexes addressing specific national or regional deviations, such as regionally specific power or testing requirements.
This document does not apply to the testing and rating of:
- water-source heat pumps or water-cooled air conditioners;
- multi-split systems where each indoor unit has dedicated piping connected directly to the outdoor unit;
- individual assemblies not constituting a complete refrigeration system.

Abstract
This document specifies:
- the test conditions and test methods for determining capacity and efficiency ratings;
- calculation methods for seasonal performance.
This applies to factory made, electric mains operated, variable refrigerant flow air-cooled air conditioners and air-to-air heat pumps with a rated capacity above 12 kW for cooling or for heating if the product has no cooling function.
In this document, “heat pumps” means “air-to-air heat pumps” and “air conditioners” means “air-cooled air conditioners”.
This document establishes a method for determining global variable refrigerant flow (VRF) performance with annexes addressing specific national or regional deviations, such as regionally specific power or testing requirements.
This document does not apply to the testing and rating of:
