This standard applies to portable air conditioners with a rated cooling capacity of less than 19,000 watts (65,000 Btu/h) that provide cooled air as described in Section 3. This standard also applies to the cooling performance of units with heating capability.

This standard does not apply to:

a) testing and rating of individual assemblies, such as condensing units or direct expansion fan coil units for separate use;

b) air conditioners that are computer or data processing room air conditioners within the scope of ANSI/ASHRAE-127-2001; and

c) room air conditioners within the scope of CAN/CSA-C368.1 or ANSI/AHAM RAC-1.

Purpose

This standard establishes a uniform, repeatable procedure or standard method for measuring specified product characteristics of portable air conditioners.

The standard methods and the recommended levels of performance, where they appear, are intended to provide a means to compare and evaluate different brands and models of portable air conditioners regarding characteristics significant to product use.

AHAM recognizes that for single duct condenser configurations of portable air conditioners, air infiltration plays a major role in determining the overall energy efficiency. The effects of air infiltration for these types of products are not presently accounted for in this standard.

This standard applies to cooling performance only and is not intended to cover the heating performance of units with heating function. Heating performance will be considered in a future revision.

The standard methods and the recommended levels of performance are not intended to preclude the exercise of ingenuity or to prevent improvement and innovation in design and performance.
