Domestic fridge design has remained largely unchanged from a consumer’s perspective since their first use in the 1920s. So a long-overdue project, instigated by Karin Goodburn, and funded by FSRN is ongoing using sensor-based technology to improve the design, performance and usage of domestic fridges.

Previous work revealed that the energy consumption of different models of fridges was down, not to design, but to how they were used.  Analysis of consumer behaviour is therefore key with focus groups providing insights into how people organise their fridges, food waste management, temperature control, willingness to have their fridges monitored and other considerations. Users prioritise functionality, efficiency, and affordability, with some interest in smart features but they have concerns about cost and privacy. ​

The next stage comprises further consumer research and testing with potential sensor systems. These may record air temperature, humidity and energy usage, and could also track how many times the door is opened. The use of a camera will monitor what goes in and out of the fridge and where items are stored.

Karin adds: “The temperature at which food is stored is central to all our work in the chilled food industry. Correct conditions must be maintained at every stage of the food chain and yet for decades that final stage – the temperature of our fridges at home – has remained a frustrating variable. I am therefore delighted that this project is looking at the issue and will, we sincerely hope, give us the information required to influence fridge manufacturers.”

The project is being led by London South Bank University and CFA is collaborating along with Food Standards Scotland, University of Leeds, WRAP, and the ZERO2FIVE Food Industry Centre at Cardiff Met University. ​
