HFO-1234ze(E) used in Ireland’s First Low-Carbon District Heating Network

Ireland’s first low-carbon district heating network located in Tallaght, Dublin, is using a heat pump system with HFO-1234ze(E) as refrigerant. The system utilises waste heat from a nearby Amazon Web Services data centre, free of cost, to provide low-carbon heating to commercial and residential customers. During normal operation, heat demand is fully covered by the data centre’s waste heat. The heat pump has four compressors with a heat recovery capacity of 2,120kW.
