HFO-1234ZE HEAT PUMPS RECOVER DATA CENTER WASTE HEAT TO SUPPLY A LARGE FINNISH DISTRICT HEATING NETWORK

Two HFO-1234ze innovative and energy efficient heat pumps have been installed in Kikkonummi, Finland, to recover waste heat from a Ericsson’s data center to supply one of the largest Finnish district heating networks.

The data center generates between 10,000 to 15,000 MWh waste heat annually, and heat pumps with a capacity of up to 26,500 kW will cover around 20 % of the district heating demand.

The heat pumps compressors have friction-free magnetic bearings, requiring no lubrication or maintenance, and, optimized for HFO-1234ze are 3 % more efficient than with the previously used HFC-134a
