Explanation of Terms

Information Provider • The company/individual (specified person) who has submitted the specified information in respect of a product model under section 6 of Energy Efficiency (Labelling of Products) Ordinance, Cap 598.
Reference Number • The number assigned to a product model by the Director of Electrical & Mechanical Services under section 8 of the Energy Efficiency (Labelling of Products) Ordinance, Cap 598.
Year • The "Year" means the year in which the reference number is assigned or, where the energy efficiency grading is calculated in accordance with the new calculation method under section 12 of the Energy Efficiency (Labelling of Products) Ordinance, the year in which the new calculation method takes effect.
Brand • The particular name used by a manufacturer or importer to identify a product range.
Model • The particular name and/or number used by a manufacturer or importer to identify an individual product within a brand.
Energy Efficiency Grade (1 to 5) • The energy efficiency grade calculated in accordance with the latest edition of Code of Practice on Energy Labelling of Products. Grade 1 being the most efficient and Grade 5 being the least efficient.
Annual Energy Consumption (kWh) • The annual energy consumption calculated by multiplying by 365 days the measured energy consumption as presented in the test report submitted to the Electrical & Mechanical Services Department for assignment of reference number.
Category •
Category 1
A refrigerator without a frozen food compartment.
Category 2
A refrigerator with a 1-star frozen food compartment.
Category 3
A refrigerator with a 2-star frozen food compartment.
Category 4
A refrigerator with a 3-star frozen food compartment.
Category 5
A refrigerator with a 4-star frozen food compartment.
Category 6
A Category 5 refrigerator incorporating means to prevent the formation of frost on contents.
Category 7

Fresh Food Volume (litre) • Means the sum of the measured net storage volume of all compartments whose operating temperature exceeds -6°C, as presented in the test report submitted to the Electrical & Mechanical Services Department for assignment of reference number.
Frozen Food Volume (litre) • Means the sum of the measured net storage volume of all frozen food storage compartments whose operating temperature is equal to or below -6°C, as presented in the test report submitted to the Electrical & Mechanical Services Department for assignment of reference number.
Freezing Capacity (kg/24hr) • Means the measured mass of food in kilograms that can be frozen to -18°C in 24 hours as presented in the test report submitted to the Electrical & Mechanical Services Department for assignment of reference number.
Rated Total Storage Volume (litre) • Means the total storage volume of a refrigerating appliance as determined and declared by the manufacturer or importer of the refrigerating appliance in accordance with the standard and requirements specified in the Code of Practice on Energy Labelling of Products (approved Code of Practice).
Refrigerant • Medium of heat transfer, which passes through the closed refrigeration circuit.
Place of Manufacture • The place/country in which the refrigerating appliance is manufactured.
Product being Supplied by Information Provider • Whether the Information Provider still supplies the product model in Hong Kong.
Supply Information Last Updated Date • The date on which the Information Provider notified the Electrical & Mechanical Services Department on whether he still supplies the product model in Hong Kong.
Energy Consumption Index (%) • Actual annual energy consumption of the refrigerating appliance / Average annual energy consumption specified in the Code of Practice x 100%. The lower the Energy Consumption Index, the better the energy efficiency.
