BS ISO 5151:2010 Non-ducted air conditioners and heat pumps. Testing and rating for performance

BS ISO 5151 is an International Standard specifies the standard conditions for capacity and efficiency ratings of non-ducted air-cooled air conditioners and non-ducted air to air heat pumps. BS ISO 5151 is applicable to ducted units rated at less than 8 kW and intended to operate at an external static pressure of less than 25 Pa.

BS ISO 5151 specifies the test methods for determining the capacity and efficiency ratings.

Residential, commercial and industrial single-package and split-system air conditioners and heat pumps are included. The equipment (taken to mean non-ducted air conditioners or non-ducted heat pumps, as well as 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) shall be factory-made, electrically driven and use mechanical compression. This International Standard is applicable to equipment utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller. It is applicable to equipment utilizing single, multiple and variable capacity components.

BS ISO 5151 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).

BS ISO 5151 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.
