Alcance
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; orc) 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.This document is not applicable to the rating and testing of the following:i) Water-source heat pumps or water-cooled air conditioners;ii) Multi-split-system air conditioners and air-to-air heat pumps (see ISO 15042:2017 for the testing of such equipment);iii) Individual assemblies not constituting a complete refrigeration system;iv) Equipment using the absorption refrigeration cycle;v) Ducted equipment (see ISO 13253:2017 for the testing of such equipment);vi) Evaporative coolers or any other cooling systems that are not of the vapour compression type;vii) Dehumidifiers;viii) Spot coolers.
