Όντας το κορυφαίο μηχανοκίνητο άθλημα στον πλανήτη, η Formula 1 διακρίνεται για την τεχνολογία της σε όλους τους τομείς. Η αεροδυναμική αποτελεί ένα σημαντικό κομμάτι και δαπανώνται χιλιάδες εργατοώρες κάθε χρόνο και φυσικά πολλά εκατομμύρια ευρώ, προκειμένου να βελτιωθεί η αεροδυναμική απόδοση ενός μονοθεσίου, κάτι που θα το κάνει ταχύτερο.

Γίνεται, όμως, η Formula 1 να βοηθήσει ένα supermarket; Αν ρωτήσεις τη Williams, θα πάρεις καταφατική απάντηση! Έχεις προσέξει ότι, όταν βρίσκεται κοντά στο ψυγείο ενός supermarket, οι θερμοκρασίες είναι χαμηλότερες; Αυτό συμβαίνει επειδή εκεί φεύγει κρύος αέρας από το ψυγείο και κάποιοι το έχουν ονομάσει «σύνδρομο του κρύου διαδρόμου».

Williams-13 Edit

Λοιπόν, η Williams Advanced Engineering σε συνεργασία με την Aerofoil Energy έχουν καταφέρει να σχεδιάσουν έναν νέο και καινοτόμο ψυγείο, το οποίο θα «κρατά» μέσα τον αέρα. Αυτό πρακτικά σημαίνει πως η έλλειψη της διαρροής θα σε κάνουν να στέκεσαι ή να περπατάς ανενόχλητος δίπλα από το ψυγείο, αλλά το πιο σημαντικό είναι πως η κατανάλωση ενέργειας για το supermarket θα μειωθεί κατά 30% και η συνολική κατανάλωση ενέργειας της Βρετανίας κατά 1%.

Williams Advanced Engineering, the division of Williams that commercialises Formula One derived technology and knowhow, has collaborated with UK start-up Aerofoil Energy to develop a new aerodynamic device that can significantly reduce the energy consumed by refrigerators in supermarkets and convenience stores.

Energy consumption makes up a significant percentage of a supermarket’s operational costs, with energy hungry refrigerators that keep the produce cool the largest consumer of power. Open fronted multi deck refrigerators that line the aisles of supermarkets consume excessive energy, with some of the cold air used to cool produce spilling out into the aisles resulting in increased energy consumption and “cold aisle syndrome” which can be unpleasant for shoppers.

Aerofoils are carefully designed and engineered profiles that control the direction of air flow. Aerofoil Energy and Williams are developing a new retrofittable aerofoil system that attaches onto each refrigerator shelf to keep more of the cool air inside the refrigerator cabinet. This innovative technology will result in significant energy savings for supermarkets and convenience stores, with corresponding benefits for their carbon footprint. The technology will also make the shopping experience more pleasant for consumers.

Aerofoil Energy are working closely with Williams to refine the aerofoil concept, utilising Williams’ proven expertise in aerodynamic design and testing from four decades of success in Formula One racing. Williams’ Advanced Engineering division is using computational fluid dynamics to model and simulate new designs before testing them at the Williams factory in Oxfordshire.

A number of supermarkets are evaluating the aerofoil technology with promising results. Sainsbury’s, the UK’s second largest supermarket chain, has been testing the product at a number of its stores. Sainsbury’s operates 1,100 stores and uses 1% of the UK’s energy in total. As part of its 20×20 Sustainability Plan, Sainsbury’s has committed to reducing its absolute operational carbon emissions by 30% by 2020 and this technology can play a key role in achieving this target.

Speaking about the trial John Skelton, Head of Refrigeration at Sainsbury’s PLC, said; “‘We’re proud to be giving our fridges a turbo boost with this fantastic aerodynamic technology. Aerofoils help the airflow around Formula One cars and can improve their performance – and that’s exactly how they help the fridges in our stores, by keeping the cold air in. This Formula One inspired innovation has already shown it can cut carbon produced by major refrigerators.”

Craig Wilson, Managing Director of Williams Advanced Engineering, added; “Williams Advanced Engineering’s mantra is to take the best of Formula One technology and knowhow and work with a range of industries to help improve their products and services. Much of our work focuses on improving energy efficiency and the collaboration with Aerofoil Energy is a perfect example of how Formula One innovations can have a tangible benefit to ordinary people and the environment. This technology has global potential and the savings in operational costs and emissions are extremely promising.”

Notes to Editors
  • A 30,000sq/ft supermarket can consume approximately 1.5 million kWh of energy each year. The ‘big 4’ supermarket operators own around 2,300 supermarkets between them, so their energy use runs into billions of kWh’s each year.
  • Even a small 2,300sq/ft convenience store will consume 116,100 kWh every year. There are around 40,000 convenience stores in the UK.
  • It is estimated that supermarkets and convenience stores account for between 5%-10% of the UK’s total energy use.
  • Between 60-70% of the energy used by a supermarket or convenience store is use by the refrigerators.
  • The main reason that open fridges consume so much energy is because of the open front. These fridges have a cold air curtain to make them safe. Much of the cold air curtain falls out and has to be continuously replaced. What is recycled mixes with warm air as the curtain is blown down the front face of the fridge, again leading to energy use in order to cool it down again.
  • The aerofoils by Aerofoil Energy have been shown to dramatically reduce the spillage of cold air from multideck refrigerators. In tests by leading manufacturers such as EPTA and the leading test centre for the Carbon Trust, RD&T, they have produced energy savings ranging from 18% to 41.5%.
