Chiller development team to share experiences at Question Time event
Waitrose says the live trials of the world’s first HFO chiller continue to show good energy savings over its current hydrocarbon equivalent, but cautioned that the machine using HFO 1234ze needs to run through the hotter months before a full appraisal can be made.
The two 180 kW units at its store in Bromley have been showing energy savings around 20 per cent better than Waitrose’s equivalent R290 propane versions.
Head of maintenance at John Lewis Partnership Peter Terry said: “So far it is performing very well, but it is early days. We need to see how it copes in summer and autumn at Bromley to get the true measure of its performance.”
Mr Terry also urged the supply chain to get involved in development of low carbon technology. He said: “We need your help to help us to innovate, to stretch the boundaries. It’s not just our carbon footprint, it’s yours too, and your children’s!”
Colleagues from chiller builder Klimatherm and compressor manufacturer Frascold will present their experience of developing and working with cooling equipment and HFOs at New Refrigerants Question Time, alongside Mr Terry.
