Scope

This Standard specifies procedures for calculating the performance of factory-made residential, commercial and industrial, electrically-driven, mechanical compression, single-package and split-system, ducted and non-ducted airconditioners and heat pumps employing air- and water-cooled condensers. This Standard covers equipment utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units controlled by a single thermostat/controller. This Standard covers equipment utilizing single, multiple and variable capacity components.
NOTE: The method in this Standard includes a combination of measured component performance, equipment operating conditions and a mathematical model to determine the appliance performance.
This Standard does not cover single circuit multiple compressor units.
This Standard can be used to quantify the following values for cooling and heating:
(a) Rated cooling capacity.
(b) Rated heating capacity.
(c) Energy efficiency ratio (EER).
(d) Coefficient of performance (COP).
This Standard does not apply to the rating of the following:
(i) Water-source heat pumps.
(ii) Multi-split airconditioners and heat pumps.
(iii) Mobile appliances having a condenser exhaust duct.
(iv) Unitary systems where there is a thermal interaction between the evaporator and condenser.
