Beyond Refrigeration: How CO₂ Systems Are Becoming the Energy Hub of Modern Food Retail
The Danfoss Smart Store ADC in Nordborg. Source: Danfoss A/S. A Danish convenience store covered 100 percent of its heating demand from refrigeration waste heat through the coldest winter in more than a decade. Over two years of operation, the same site exported 36 MWh of surplus heat to its city's district network and saved close
Power, Water, and Heat: How Site Resources Now Decide the Refrigerant in a Data Center
For an engineer reading a data center brief in 2026, the first constraint is rarely the heat load. It is whether the site has the electricity, the water, and a use for the rejected heat to run a given cooling scheme at all. The cooling technology, and with it the refrigerant, follows from what the
Magnetic Refrigeration: A Revolutionary, Disruptive Cooling Technology
As the global demand for energy-efficient and environmentally friendly cooling solutions intensifies, magnetic refrigeration emerges as a groundbreaking technology poised to transform the refrigeration industry. Leveraging the magnetocaloric effect, this innovative approach promises significant advantages over traditional cooling methods. Recent advancements are bringing magnetic refrigeration closer to commercial reality, signaling a new era in cooling

CO₂ Refrigeration & Heat Recovery
A Danish convenience store covered 100% of its heating demand from refrigeration waste heat — through the coldest winter in over a decade, and exported the surplus to the city grid. This issue looks at what happens after the refrigerant decision is made: how CO₂ systems perform once installed, and how much of their potential […]
