For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO/IEC Guide 98-3, Uncertainty of measurement — Part 3: Guide to the expression of uncertainty in measurement (GUM:1995) ISO 81 7, Refrigerants — Designation system ISO 1 3253, Ducted air conditioners and air-to-air heat pumps — Testing and rating for performance ISO 1 5042, Multiple split-system air conditioners and air-to-air heat pumps — Testing and rating for performance 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 non-ducted air conditioner encased assembly or assemblies, designed primarily to provide free delivery of conditioned air to an enclosed space, room or zone NOTE 1 It can be either single-package or split-system and comprises a primary source of refrigeration for cooling and dehumidification. It can also include means for heating other than a heat pump, as well as means for circulating, cleaning,humidifying, ventilating or exhausting air. Such equipment can be provided in more than one assembly, the separated assemblies (split-systems) of which are intended to be used together. NOTE 2 An enclosed space, room or zone is known as a conditioned space. 3.2 non-ducted heat pump encased assembly or assemblies designed primarily to provide free delivery of conditioned air to an enclosed space, room or zone and includes a prime source of refrigeration for heating NOTE 1 It can be constructed to remove heat from the conditioned space and discharge it to a heat sink if cooling and dehumidification are desired from the same equipment. It can also include means for circulating, cleaning, humidifying,ventilating or exhausting air. Such equipment can be provided in more than one assembly; the separated assemblies (splitsystems) of which are intended to be used together. NOTE 2 An enclosed space, room or zone is known as a conditioned space. 3.3 standard air dry air at 20 °C and at a standard barometric pressure of 1 01 ,325 kPa, having a mass density of 1,204 kg/m 3 3.4 indoor discharge airflow rate of flow of air from the outlet of the equipment into the conditioned space See Figure 1 . 3.5 indoor intake airflow rate of flow of air...
