Specifies the standard conditions on which the ratings of single-package and split-system non-ducted air conditioners employing air- and water-cooled condensers and heat pumps employing air-cooled condensers are based, and the test methods to be applied for determination of the various ratings. This international Standard is limited to systems utilizing a simple refrigeration circuit and having one evaporator and one condenser. Also, specifies the test conditions and the corresponding test procedures for determining various performance characteristics of these non-ducted air conditioners and heat pumps.It does not apply to the testing and rating for water-source heat pumps, multiple split-system air conditioners and heat pumps, units designed for use with additional ducting, or mobile (windowless) units having a condenser exhaust duct.
Determined parameters
The following tests are executed:
- Cooling capacity rating test, maximum cooling test, minimum cooling test
- Heating capacity rating test, maximum heating test, minimum heating test
- Enclosure sweat and condensate disposal test
- Freeze-up test
