Synthetic greenhouse gases are used as refrigerants in cooling systems worldwide and make a considerable contribution to CO2 emissions and global warming as a result of leakages.
Danfoss leads the market within solutions which make it possible to replace the synthetic greenhouse gases by the natural refrigerant CO2 in a number of industrial sectors.
In Europe, around 5% of retail stores selling food have fully or partially replaced synthetic refrigerants with CO2. As for the remaining parts of the world, only very few have taken this step.
Denmark is a good example – here, all newly built and reconstructed shops use CO2 as refrigerants, since Danish regulations on the use of refrigerants has enforced the amendment. With more than ten years’ experience in developing CO2-based compressors, Danfoss has supplied solutions to a large proportion of the CO2 systems installed in retail stores throughout the world. In addition to delivering components,
Danfoss also contributes by building up the retail chain’s knowledge about CO2 technologies. In addition to reducing CO2 emissions, the new CO2 systems have proven to be equally efficient or even more efficient than systems with conventional synthetic refrigerants.
In 2009, Danfoss installed energy-efficient solutions in major supermarket chains worldwide – in 230 shops in United Kingdom and 100 shops in Australia, among others.
The supermarket chains are aware that investments in energy savings can help them get through a period of decrease in consumer purchases. Danfoss’ solutions, called ADAP-KOOL®, have so far resulted in energy savings of an average of 15-20% in the shops.
The ADAP-KOOL® solutions covered a central monitoring system, among other things, which registers data on the different cooling, lighting and air-conditioning units and optimises and adjusts their energy consumption on an ongoing basis.
