Scope:
This document specifies the standard conditions for capacity and efficiency ratings of non-ducted portable air-cooled air conditioners having a single exhaust duct and non-ducted portable air-cooled heat pumps having a single exhaust duct. Such air conditioners and heat pumps may include an evaporatively cooled condenser cooled by air and the evaporation of:
a) condensate collected from the evaporator;
b) external supplementary water stored in a supplementary water tank; or
c) both a) and b).
This document also specifies the test methods for determining the capacity and efficiency ratings.
This document applies to equipment that is factory-made, electrically driven and uses mechanical compression. This document is applicable to equipment utilizing one or more refrigeration systems.
