Boilers & Heating
Energy efficient
supermarket of the future
DANFOSS HAS COMMENCED CONSTRUCTION OF ONE OF THE WORLD’S MOST ENERGY- EFFICIENT SUPERMARKETS TO SHOWCASE REFRIGERATION AND HEATING TECHNOLOGIES.
THE SMART STORE supermarket will be completed next year.
Instead of allowing the heat pro- duced by cooling cabinets and freezers to go to waste, it will be captured and reused to provide heating for the supermarket and the local community through district energy.
The cooling system in the new supermarket will also run on carbon dioxide.
Danfoss Climate Solutions president of refrig- eration & AC controls, Kristian Strand, said the goal of the project is to show how easy and profit- able it is to decarbonise the economy and ensure reliable and sustainable energy use.
“Heating and cooling are the largest energy con- sumers in supermarkets. The solutions we are
building here represent the core of Danfoss solu- tions and will showcase how we can approach zero energy use in food retail together,” Strand said.
“The state-of-the-art supermarket is situated right next to Danfoss’ headquarters and will lead the way for how supermarket chains around the world can build climate-friendly and sustainable stores with the technologies that al- ready exist today.”
The site will also serve as an Application De- velopment Centre where Danfoss will work to- gether with partners to co-develop new technol- ogies and explore interfaces in the energy system surrounding energy storage.
“THE GOAL IS ZERO ENERGY USE IN FOOD RETAIL”
“The supermarket will be the focal point for a new part of our campus, where all buildings will be energy-efficient and meet special sustainabil- ity requirements,” he said.

association, BALS, will rent the building from Danfoss and will install a COOP 365discount su- permarket.
BALS, which works together with COOP, has a total of 13 stores in the area around Sønderborg in Denmark and since 2015 has consistently re- duced the consumption of energy in its stores.
So far, they have cut 44 per cent of their total CO2 emissions. Therefore, it was a natural next step that BALS became a partner in the project.
BALS managing director, Lars G. Anders- en, said its supermarkets have nearly no heat- ing costs.
“The heat comes from our freon-free refrigera- tion systems, solar cells, and heat pumps,” he said. “It is an advantage with the current energy prices, and it reduces our CO2 emissions. We are proud to be part of one of the most energy- efficient supermarkets in the world and test the solutions that can help buildings become cli-
mate neutral.”
Danfoss will also establish a showroom in the
supermarket building so all installations are vis- ible to visitors and customers.
Heat recovery delivers quick ROI
THE DANFOSS HEAT Recovery Unit delivers strong environmental benefits as well as signifi- cant reductions on heating bills—all delivered with a short ROI.
The Danfoss Heat Recovery Unit (HRU) is de- signed to recover the waste heat from CO2 refrig- eration installations.
The reclaimed heat can be used for domestic heating purposes such as store heating, hot wa-
ter and where possible can be sold to local dis- trict heating companies.
Recent existing installations of the HRU have shown a heating bill reduction up to 90 per cent and a cut in the carbon footprint up to 50 per cent, ensuring a quick ROI and helping to achieve ambitious CO2 targets.
HRU Project Manager at Danfoss. Dawid Law- reszuk, said the unit has delivered strong results for customers.
“It is well tested with more than 100 installa- tions in Europe. With the short ROI, the heat recovery unit would make a lot of sense for many supermarkets with a CO2 refrigeration plant,” he said.
ROI is one to three years as well as easy in- stallation with remote access via Danfoss free cloud based ECL portal or via other protocols, such as Modbus.
