Developing novel breakthrough technologies

Within the Frisbee project we are developing new and novel technologies that have the potential to reduce energy and refrigerant emissions and to improve food quality in the cold chain. We are developing seven technologies (superchilling, supercooling, smart packaging, air cycle refrigeration, magnetic refrigeration, vacuum insulated panels and nanoparticles for improved heat transfer in refrigeration systems).

Although work is still ongoing highlights to date include:

• Design of a magnetic domestic refrigerator and all its components

• Development of ‘smart’ thermal packaging which contains nano encapsulated phase change materials
• Comprehensive modelling and a design guide for using air cycle refrigeration in the food cold chain
• Development of the superchilling process for the pork cold chain
• Work to show that pork can be supercooled (i.e. maintained at temperatures below its initial freezing point) without the detrimental effects of freezing
• Information on the applicability of VIPs (vacuum insulated panels) throughout the cold chain and best methods to apply VIPs economically
• A review of the benefits and issues surrounding the application of nanoparticles in refrigeration systems
