scope:

This standard prescribes a method of testing for obtaining cooling capacity and airflow quantity for rating room air conditioners and packaged terminal air conditioners.

For purposes of this standard:

(a) A room air conditioner is defined as an encased assembly designed as a unit, primarily for mounting in a window or through the wall or as a console. It is designed primarily to provide free delivery of conditioned air to an enclosed space, room, or zone. It includes a prime source of refrigeration and dehumidification and means for circulating and cleaning air and may also include means for heating and ventilating.

(b) A packaged terminal air conditioner is a factory selected combination of heating and cooling components, assemblies, or sections, intended to serve an individual room or zone.

Room conditioners employing water-cooled condensers are included in this standard.

This standard does not prescribe methods of testing for obtaining heating capacity (see ASHRAE Standard 58-1986).
