Refrigeration plays a massive role in the energy consumption of buildings. For example, in supermarkets it can account for up to 50% of the total energy use.
Besides energy expenditure, refrigeration can also have a damaging impact on emissions. For example,
releasing 1 kilogram of conventional refrigerant R404 to the air is equivalent to releasing 4000
kilograms of carbon dioxide.
That is why the EU’s F-gas regulation is already limiting the use of these conventional
refrigerants and will completely ban them by 2030.
Sustainable refrigeration uses CO2 as refrigerant. Using carbon dioxide as
refrigerant limits the environmental impact and drastically reduces the energy consumption of your
building. Besides being an effective and sustainable refrigerant, CO2 refrigeration also produces
heat that can be used for example in heating the building.
