A new aerodynamic device has the potential to reduce the energy consumption of supermarket refrigerators by up to 41.5 percent.
The product, currently being developed by Williams Advanced Engineering in collaboration with Aerofoil Energy, can be clipped onto existing cabinets, making it easy for companies to upgrade their stores.
Supermarkets and convenience stores consume a huge amount of energy every year. A single 30,000 sq ft (2,787 sq m) supermarket uses in the region of 1.5 million kWh of energy a year, and with the biggest four supermarket operators in the UK running some 2,300 stores combined, the energy figures for the industry are off the chart, running into the billions of kWh’s every year.
Refrigerators in supermarkets and convenience stores are responsible for a large chunk of that energy consumption – according to Williams Advanced Engineering, as much as 70 percent. The company, a division of Williams that commercializes Formula One developed technologies, believes that aerofoils (also known as airfoils) can play a part in increasing efficiency.
Utilizing its experience of aerodynamic design and testing in Formula One racing, the company is working with Aerofoil Energy, using computational fluid dynamics to model and simulate new designs, later testing them at the Williams factory in Oxfordshire.
The under-development product is designed to attach to each shelf of a cabinet, manipulating the air flow to keep the cool air inside, meaning that the units don’t have to work as hard to keep produce at the desired temperature. The aerofoils are retrofittable, meaning supermarkets won’t have to purchase all-new refrigerators to take advantage of them.
