DESIGN IDEAS
When making a quick pit stop, it’s good to know that technology derived from your day job – if you race F1 cars, that is – brings efficiencies to your food shopping
AEROFOILS KILL THE CHILL IN SUPERMARKET AISLES
Sainsbury’s is the first UK supermarket to roll out revolutionary aerofoil technology on its fridges in the cold aisles across all of its supermarkets. Inspired by Formula 1, the newenergy saving technology helps to chill food to the same temperaturewhilemaking the aisleswarmer for customers. The aerofoils,whichwill be introduced in
aisles stocking products such as cheese, yoghurts andmeat,will account for an energy reduction that equates tomore than 320million kettles boiled. The fridgeswill remain at the same temperature to keep food cool and fresh,while the aisleswill be warmer by up to 4°C. The state-of-the-art aerofoil technology,
which is derived fromthe fast-pacedworld of Formula 1, prevents cold air fromthe fridges spilling out into the aisle by steering it directly back down into the fridge unit. The principle for the technology replicates aerofoil designwith an aerodynamic “profile” that redirects air flow, similar to those seen on cars. The aerofoil systemis attached to the front of the refrigerator’s shelves to keepmore of the cool air inside the fridges in the cold aisle of a supermarket.
energy saved. By looking outside our industry, and borrowing technology froman industry that is renowned for its speed and efficiency, we are accelerating how we are reducing the impact on the environment whilemaking shopping in Sainsbury’s a more comfortable experience.” In 2010,Williams Grand Prix Engineering
Paul Crewe, head of sustainability at
Sainsbury’s, said; “By keeping the cold air in our fridges using this technology, we’ll see an energy reduction of up to 15 per cent which, whenmultiplied across all of our supermarkets, is a significant amount of
Limited began diversifying its operations, leading to the establishment of theWilliams Advanced Engineering division, which has now becomeWilliams Advanced Engineering Limited. Its role is to commercialise Formula One derived innovation and expertise, and has created this technology in collaboration with UK start-up Aerofoil Energy. Managing director CraigWilson said: “Our collaboration with Aerofoil Energy is a perfect example of how Formula 1 derived innovations can have a tangible benefit to the general public, and the environment.” The new fridge technology will be
installed across the Sainsbury’s estate by themiddle of 2018,making Sainsbury’s the first retailer to retrofit the technology on such a large scale.
