ISO 5151:2017 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.<\/p>\n
ISO 5151:2017 is applicable to the following equipment:<\/p>\n
– non-ducted air-cooled air conditioners and non-ducted air-to-air heat pumps; or<\/p>\n
– 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.<\/p>\n
ISO 5151:2017 is limited to:<\/p>\n
– residential, commercial and industrial single-package and split-system air conditioners and heat pumps;<\/p>\n
– factory-made, electrically driven and use mechanical compression;<\/p>\n
– utilizing single, multiple and variable capacity components;<\/p>\n
– multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat\/controller.<\/p>\n
The requirements of testing and rating contained in this document are based on the use of matched assemblies.<\/p>\n
ISO 5151:2017 is not applicable to the rating and testing of the following:<\/p>\n
a) water-source heat pumps or water cooled air conditioners;<\/p>\n
b) multi-split-system air conditioners and air-to-air heat pumps (follow ISO 15042 for the testing of such equipment);<\/p>\n
c) mobile (windowless) units having a condenser exhaust duct;<\/p>\n
d) individual assemblies not constituting a complete refrigeration system;<\/p>\n
e) equipment using the absorption refrigeration cycle;<\/p>\n
f) ducted equipment except for those specified in this clause (follow ISO 13253 for the testing of such equipment).<\/p>\n
ISO 5151:2017 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.<\/p>\n
