Refrigerant conversion saves energy for ASDA’s Liverpool superstore

Substantial energy savings for refrigeration at ASDA’s Hunts Cross store have been achieved by conversion to Honeywell’s R407F refrigerant.

The potential of Honeywell’s Genetron Performax LT refrigerant (R407F) to reduce energy consumption for medium-temperature refrigeration applications has been demonstrated by a long-term replacement trial at ASDA’s Hunts Cross store in Liverpool. The tests confirm results obtained by other European supermarkets of 13% less energy than systems using R407A and up to 20% less than R404A.

Brian Churchyard, head of refrigeration at ASDA, says, ‘The benefits we are seeing are very much a combination of ASDA system optimisation and favourable properties of the refrigerant. I feel the most important aspect for this conversion to Genetron Performax LT will be its efficiency and lower GWP versus R404A, which will enable us to reduce both direct and indirect emissions. I am impressed by the energy improvement.’

This refrigerant is a blend of R32, R125 and R134a. It can be used for new commercial installations and to retrofit existing R404A, R407A and R22 installations.

Conversion of existing R404A installations requires only minor adjustment to the expansion valve. Conversion of existing R22 installations requires only a single oil change and no adjustment to the expansion valve.

The conversion can be done very quickly, without disrupting business. At ASDA, the conversion was done over a weekend, and the start-up was trouble-free. The retrofitting cost is paid off through energy savings.
