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).¹

Purpose

The purpose of this standard is to

(a) establish a uniform method of testing for obtaining rating data,

(b) specify types of test equipment for performing such tests,

(c) specify data required and calculations to be used, and

(d) list and define the terms used in testing.
