Danfoss has opened Smart Store in Denmark – it will act as a test centre for energy efficiency technology.
The store is expected to be 50% more energy efficient when compared to a typical supermarket – with a first-generation CO2 refrigeration system – and 20-30% more efficient than a store already fitted with energy efficiency measures.
Commenting on the launch, Jürgen Fischer, President, Danfoss Climate Solutions, said:
We have developed this new Smart Store supermarket with partners and customers to demonstrate that it is possible to build a climate friendly and super-efficient facility, using world-class heating and cooling technology. Our new Smart Store proves that the future is now. This supermarket is purpose-built for the world ahead of us; a world of more urbanisation, larger populations, greater energy demands, a growing need for cooling, and efficient food storage.
Supermarkets and retail food stores are big energy consumers, plus the average profit margin for a large food retailer is just 1.7%, which puts every operating cost under scrutiny. Energy is an area where significant savings can be achieved with relatively low investment and good payback times.
The range of new solutions in the Smart Store demonstrate the significant savings that can be achieved in supermarkets, with a typical payback time of three to four years.
Solar power is the supermarket’s primary energy source with 100 kW solar panels on the building’s roof providing green energy to support the supermarket operations. Heat capture and reuse is also key to the energy efficiency of the supermarket with up to 90% reduction in heating costs expected. The Smart Store is fitted with heat recovery units, designed to recover the waste heat from all the refrigeration systems. The recovered heat is reused to heat up the store and produce domestic hot water, with any additional heat shared with residents of the surrounding town through a district energy network.
Other initiatives such as installing doors on refrigerator and freezer cases will save around a third on energy use, while the choice of LED lighting uses up to 85% less electricity than incandescent bulbs. Automation and monitoring of the Smart Store adds another layer of energy saving.
Jürgen Fischer added:
Danfoss has reimagined what food retail stores could look like in the 21st century. For the first time, all of Danfoss’ most cutting-edge technology and energy efficient food retail solutions are being brought together into one retail site. But the new Smart Store supermarket is only the beginning. Because it will also serve as an Application Development Center, a ‘live’ testing site for new technologies which we hope will inspire food retailers around the world to move towards zero emissions supermarkets – while making economic sense.
