Scope:
This document 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 document 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 document 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;
— 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.
