To estimate HFC and PFC emissions, all refrigeration equipment is split into two groups:
factory-charged equipment and all other equipment that is charged with refrigerant on
site. The amount of new refrigerant used to charge all other equipment (charged on site
after assembly) is assumed to be the amount of HFC refrigerant sold each year minus that
used in factory-charged equipment and used to top up all non-factory-charged equipment.
Factory-charged equipment consists of all equipment charged in factories (both in
New Zealand and overseas). This includes all household refrigerators and freezers and all
factory-charged, self-contained refrigerated equipment used in the retail food and
beverage industry. All household air conditioners and most medium-sized commercial air
conditioners are also factory charged, although some extra refrigerant may be added by
the installer for piping.
It is estimated there are about 2.2 refrigerators and freezers per household in
New Zealand. This estimate includes schools, factories, offices and hotels. Imported
appliances account for around half of new sales each year, with the remainder
manufactured locally. New Zealand also exports a significant number of factory-charged
refrigerators and freezers.
Commercial refrigeration includes central rack systems used in supermarkets, selfcontained
refrigeration equipment, chillers used for commercial building air-conditioning
and process-cooling applications, rooftop air conditioners, transport refrigeration systems
and cool stores. In many instances, these types of systems are assembled and charged on
site, although most imported units may already be pre-charged. Self-contained
