Refrigerators are often the first electrical appliance a household buys. Fridges and freezers are often responsible for a large proportion of a household’s energy consumption. For example in Brazil this is on average 30%.
Domestic refrigeration is the subsector with the highest number of units. The global stock is estimated to be approaching 1,500 million units. 100 million units are produced annually.
|Typical application||refrigerators, refrigerator-freezers with usually a smaller freezing compartment in or attached to the refrigerator, upright freezers, chest freezers|
|Typical end-users||Predominantly households|
|Main refrigerants used||HFC-134a (60% of existing units), 50 to 250 g|
|Natural refrigerant alternative||HC-290 (propane) and HC-600a (isobutane) are used in 50% of newly produced refrigerators.
Hydrocarbon (HC) refrigerators need less refrigerant than HFC refrigerators and a typical HC refrigerator with a volume of ca. 250 l contains ca. 55 g HC-600a.
|Growth rate / future demand||Growth rates depend on the region, as saturation rates are already above 100% in some developed countries like the US or in Western Europe, but are still as low as around 20% in some developing countries.
