version of AS/NZS 4776.1.2:2008 is the version that existed at the date this Determination came into force.

5 Specified product class covered by this Determination

      (1)          This Determination covers air-cooled and water-cooled liquid-chilling packages with a cooling capacity of 350 kW or above.

             Note 1: This subsection reflects the scope specified in clause 1 of AS/NZS 4776.1.1:2008.

             Note 1: This subsection specifies products that are covered by the Determination. See subsection (3) for products that are not covered.

      (2)          The products covered by this Determination form a single product class for the purposes of the Act.

      (3)          For subsection 23 (2) of the Act, this Determination does not cover:
          (a) liquid-chilling packages driven other than by an electric motor;
          (b) air-cooled liquid-chilling packages with centrifugal fans;
          (c) liquid-chilling packages with remote condensers;
          (d) liquid-chilling packages for fluids other than water;
          (e) free cooling liquid-chilling packages (air cooled);
          (f) free cooling liquid-chilling packages (water cooled);
          (g) heat pump (reverse cycle) liquid-chilling packages; or
          (h) heat recovery liquid-chilling packages.

             Note: This subsection reflects the exclusions specified in clause 1 of AS/NZS 4776.1.1:2008.

      (4)          In this section:

      centrifugal fan means a fan impeller that produces pressure from the centrifugal force (created by rotating the air column contained between the fan and blades) and kinetic energy imparted to the air by its velocity leaving the impeller.

      condenser means a vapour condenser in a refrigeration system, where the refrigerant is liquefied and discharges its heat to the environment.

      free cooling means how ambient air, temperature permitting, is used to cool the chilled water supply, utilising, for example, compressors, evaporators, condensers, as in a conventional air cooled chiller, but with the addition of an integral dry cooler circuit.

      free cooling  liquid-chilling package (air cooled) means a liquid-chilling package that has an additional integral free cooling circuit with a self-contained control system.

      free cooling  liquid-chilling package (water cooled) means a liquid-chilling package that has been designed with the appropriate controls and valves to be able to utilise condenser water which is at a temperature lower than the required leaving chilled water temperature, typically 10°C to 12.5°C to provide cooling without the need to run the compressor.

      heat pump (reverse cycle) liquid-chilling package means a liquid-chilling package that has components and controls that enable the reverse of the flow of refrigerant so that the water leaving the evaporator vessel of the chiller is heated in the process rather than cooled.

      heat recovery liquid-chilling package means a liquid-chilling package that has components and controls that allow for heat to be reclaimed from the refrigeration and to be used for such applications as heating water for use in the air conditioning or heating system.  The chiller must be specifically designed
