A Danish supermarket fulfills 95 percent of its heating demand from its own cooling display cases. The chain has installed Danfoss heat recovery units and managed to halve its CO2 footprint in five years. Imagine if this was done in all supermarkets in the world.

The specific Danfoss components that Delfield used were the DCL filter drier, the TUB thermostatic expansion valve (TXV) for R-290, and the ERC electronic temperature controller. Each played a part in helping Delfield meet their goals.

How can refrigeration professionals comply with the EU F-gas regulation? What technologies can be used to make the transition to compliant refrigerants? And how can professionals specify, install, service, and use these solutions? Innovation and new approaches require know-how, and Danfoss is offering extensive, user-centric content that builds know-how through training, education, and the sharing of knowledge with the company’s partners, customers, and other stakeholders such as policymakers on several platforms.

As authorities and customers focus on energy efficiency standards and ratings to understand not just what a commercial refrigeration unit costs to buy, but what it costs to operate, the refrigeration design engineer needs to look again at the fundamentals and consider new approaches.

Testing at the Danfoss Cooling Application Development Center (ADC) in Baltimore, US demonstrated how a refrigeration customer could remove 572 tons of CO₂ from the atmosphere every year and still ensure the delivery of cold beer.

Diaper Poultry are really pleased with the result. Compared to the old refrigeration solution, the new Optyma™ solution is only about a quarter of the size, it works much more quietly and at the same time it is just as efficient as the old system.
