Frigesco has been awarded funding of £102 000 from the Department of Energy & Climate Change to develop its highly efficient flash defrost technology for air-source heat pumps. The technique is said to be capable of reducing supermarket cooling-energy costs by up to 20%.

The grant will be used to fund joint research by Frigesco and heat-pump specialist Glen Dimplex to develop flash defrost technology for application in air-source heat pumps. It saves all the electrical power normally used for defrost.

A flash-defrost system will be trialled with a production version of a Glen Dimplex A16M heat pump.

The concept is based on storing heat rejected by the refrigeration system in a phase-change material and using it for defrosting.
