Frigesco’s flash defrost system shortlisted for two  national innovation awards

UK:  Frigesco’s pioneering flash defrost for refrigeration systems has been shortlisted in two categories of the forthcoming National ACR Awards 2015.

The technology, which can reduce supermarket cooling energy costs by up to 20 per cent, has been shortlisted for Refrigeration Product of the Year, and Environmental Champion.

It follows success for Frigesco in the recent Cooling Industry Awards, where its flash defrost system took the top award for Refrigeration Innovation of the Year (Component or Process).

David Walter, managing director of Frigesco, said: “It is obviously very pleasing to receive this high profile recognition for flash defrost, doubly so as it comes from the industry itself. People have been quick to see the potential of flash defrost to cut energy use, and transform end users’ refrigeration running costs.”

The patented technology uses a phase-change material to capture waste heat produced by a refrigeration system and use it to defrost evaporators, in the process boosting efficiency, extending plant life, safeguarding food hygiene, and improving safety for store staff.

The innovation, developed by a team headed by Professor Tom Davies, is currently being trialled in working stores by leading UK supermarkets. Once proven in cold rooms, the next stage will be to apply the system to refrigerated display cases.

Conventional methods of defrosting require electric heaters, or “hot gas” from the system, which makes the refrigeration plant less efficient. These additional energy inputs cost stores thousands of pounds a year.

Frigesco’s system absorbs and removes waste heat from the refrigeration system in the normal course of operation, increasing its efficiency in the process by adding a sub-cooling effect, and then using this “free” energy to carry out highly efficient defrosts.

Although the main benefit is a reduction in energy use and lower plant running costs, the system delivers other attractive benefits for retailers, including:

  • Improved food hygiene and safety due to more effective defrosts, and more stable temperatures in the refrigerated space;
  • Increased working life and fewer breakdowns for refrigeration plant, due to more complete defrosts and improved equipment operation;
  • Potential reductions in equipment capital costs due to design optimisation possible with the use of flash defrost;
  • Reduction in a retail store’s overall maximum electrical draw, giving “head room” in locations where power supplies are near the limit, which may be vital in extreme weather conditions, as experienced in hot summer months;
  • The more efficient defrost process stops the build-up of frost on floors and walls in the immediate environment of refrigeration plant, eliminating slip hazards for store staff.

The winners of the National ACR Awards 2015 will be announced at a gala awards dinner, being held at Birmingham Town Hall on 29 January.
