Applicable version of documents incorporated into standards

(2)          For the purposes of this Determination the applicable version of any document, including a standard, that:

(a)     is referred to in a standard under the heading ‘Referenced Documents’, or under an equivalent heading in a standard; and

(b)     must be applied to give effect to this Determination or a standard referred to in this Determination,

is the version of the document, including a standard, that existed at the date this Determination came into force.

Note:                 For example, clause 2.3 of AS/NZS 4965.2:2008 provides that the unit shall be operated at rated capacity under the cooling capacity test in accordance with AS/NZS 4965.1:2008 to determine cooling capacity, effective power input, energy efficiency ratio and compliance with minimum EERS cooling requirements.  The applicable version of AS/NZS 4965.1:2008 is the version that existed at the date this Determination came into force.

5              Specified product class covered by this Determination

Note 2:            This subsection reflects the exclusions specified in clause 1.2 of AS/NZS 4965.2: 2008.

         (4)   In this section:

brine-to-air heat pump means a heat pump which consists of one or more factory-made assemblies which normally include an indoor conditioning coil with air-moving means, compressor(s), and refrigerant-to-brine heat exchanger(s), including means to provide both cooling and heating, cooling-only, or heating-only functions.

Note 1:             When such equipment is provided in more than one assembly, the separated assemblies should be designed to be used together.

Note 2:             Such equipment may also provide functions of sanitary water heating, air cleaning, dehumidifying, and humidifying.

Note 3:             This is the same meaning as in clause 3.1 of AS/NZS 3823.1.3:2005.

close control air conditioner means a unitary air conditioner designed for high sensible heat ratio applications that are capable of maintaining close control of both temperature and humidity.  A close control air conditioner consists of one or more factory-made assemblies, which include a compressor, a direct expansion evaporator, an air-moving device and air-filtering devices, and may include a condenser, a humidifier or a reheating function.

Note:               This is the same meaning as in clause 4.1 of AS/NZS 4965.1:2008.

close-coupled row based cooling units means cooling devices that are designed:

(a)        to be mounted in a row containing the rack enclosures and are placed in such a way that the unit takes air from a hot aisle, cools it and discharges it to a cold aisle; and

(b)       for up to a minimum of 35°C (dry bulb) entering air temperature, with operating data published by the manufacturer indicating such.

ground loop sourced heat-pump means a brine-to air heat pump using a brine solution circulating through a subsurface piping loop functioning as a heat source/heat sink.

Note 1:             The heat exchange loop may be placed in horizontal tranches or vertical bores, or be submerged in a body of surface water.

Note 2:             The temperature of the brine is related to climatic conditions and may vary from minus 5 degrees Celsius to 40 degrees Celsius.

Note 3:             This is the same meaning as the term ‘ground-loop heat pump application’ in clause 3.1.3 of AS/NZS 3823.1.3:2005.

ground water sourced heat-pump means a water-to-air heat pump using water pumped from a well, lake or stream functioning as a heat source/heat sink.

Note 1:             The temperature of the water is related to climatic conditions and may vary from 5 degrees Celsius to 25 degrees Celsius for deep wells.

Note 2:             This is the same meaning as the term ‘ground-water heat pump application’ in clause 3.1.2 of AS/NZS 3823.1.3:2005.

multi-split system means a split system air conditioner with a refrigeration system having two or more independently controlled indoor units.

Note:                 This is the same meaning as in subclause 1.6.12 of AS/NZS 3823.2:2011.

packaged unit means a self contained air conditioning unit including the evaporator, compressor, condenser, fans and associated equipment ready for installation and that:

(a)        can be wholly located outside and distribute conditioned air through ductwork; or

(b)       can be mounted with one part of the housing outside and the other part inside; and

(c)        can service an individual room, a zone or multiple zones.

split system  means an air conditioner with separate indoor and outdoor components that are connected with refrigerant piping. The indoor unit usually lies within the conditioned space and may be installed or portable or mobile.

Note 1:             The indoor unit in some configurations may feed into a duct system. Some split ducted system indoor units may have no fan and are designed to operate with an existing system (for example, a gas heater).

Note 2:             This is the same meaning as in subclause 1.6.21 of AS/NZS 3823.2:2011.

spot cooler means a unitary air conditioner that lies wholly within a conditioned space and that draws air for both the evaporator and condenser from the conditioned space and expels both of these back into the conditioned space.

Note:                This is the same meaning as in subclause 1.6.22 of AS/NZS 3823.2:2011.

unbalanced air conditioner means a unitary air conditioner that lies wholly within a conditioned space and that draws air from the conditioned space and expels this to outdoors. An unbalanced air conditioner is usually ducted (where the exhaust air from the heat exchanger is expelled from the conditioned space via a flexible duct, pipe or opening) but may be connected to a pipe or other opening such as a window. These units are typically portable or mobile.

Note:                This is the same meaning as in subclause 1.6.30 of AS/NZS 3823.2:2011.

unitary air conditioner means an air conditioner where the evaporator, condenser and associated refrigeration components (for example, the  compressor) are contained within a single casing. 

Note 1:             Unitary air conditioners may be non-ducted (for example, window/wall units) or ducted (for example, single packaged units).

Note 2:             This is the same meaning as in subclause 1.6.31 of AS/NZS 3823.2:2011.

water-to-air heat pump means a heat pump which consists of one or more factory-made assemblies which normally include an indoor conditioning coil with air-moving means, compressor(s), and refrigerant-to-water heat exchanger(s), including means to provide both cooling and heating, cooling-only, or heating-only functions.

Note 1:             When such equipment is provided in more than one assembly, the separated assemblies should be designed to be used together.

Note 2:             Such equipment may also provide functions of sanitary water heating, air cleaning, dehumidifying, and humidifying.
