Danfoss said during a webinar on ‘Zero net energy supermarkets: towards a sustainable future’ last week (22 February) that it had partnered with VMA – a German solar energy equipment manufacturer – to install a CO2-based integrated heating and cooling system powered by solar energy at a German supermarket.

Dirk Leinweber, director sales (food retail) at Danfoss, explained during the webinar (hosted by sheccoBase – the market intelligence arm of shecco, publisher of this website, and Danfoss)webinar, that the German supermarket uses a 100 kW peak solar photovoltaic system, a lithium-ion battery bank, and two electric vehicle chargers of 22 kW each.

“This all goes to one central energy management system in the supermarket. All the data points are collected and provided to the owner of the supermarket,” Leinweber said.

“The intelligence of that, behind the scenes, is machine learning and data analytics that we will be increasingly applying here to improve the system,” enthused Leinweber. “We believe that we can ultimately reduce the energy bill of this supermarket by 35%, which is not only good for the supermarket owner but also for our project partners and the planet.”
