The industrial heat pump "Frigg" delivers steam for feed production to Felleskjøpet Agri at Skansen in Trondheim. The technology secured the Heat Pump Award 2024 – large installations.
Recovers waste heat and reduces electricity consumption
Aneo Industry unveiled the heat pump "Frigg" in Trondheim earlier yesterday, with Environment Minister Andreas Bjelland Eriksen among others in attendance. The heat pump recovers waste heat and will help reduce electricity consumption at the Felleskjøpet Agri factory by approximately 5 GWh annually.
– The need for industrial heat pumps that can deliver high temperatures is significant now that the industry is phasing out fossil energy. That's why we want to highlight projects that lead the way and take initiative, said Managing Director Rolf Iver Mytting Hagemoen of the Norwegian Heat Pump Association when he awarded the Heat Pump Award 2024 – large installations.
Two tons of process steam per hour
Christian Schlemminger, operations manager at Aneo Industry, is behind the solution. – The heat pump delivers two tons of process steam per hour, he states.
The process requires water vapor at 130 °C and 2 bar. It is produced in two stages: the first stage is based on an industrial ammonia machine that generates low-pressure steam. In the second stage, steam compressors ensure the steam pressure is compressed to the desired level.
– Both of these systems exist in their own domains, but no one has dared to combine them in this way and at this scale. Both systems have to be pushed to work together, notes Schlemminger.
Extracts heat from the production process
The heat pump supplies both steam and hot water to the production process – and also extracts heat from it. After heating, the feed must be cooled down to about 20 degrees. – We channel this heat into the heat pump, explains Schlemminger. The steam is distributed through a newly built steam network in the factory, and the existing electric boiler is used to start the production process.
– Such integration, as close to the core process as possible, allows us to deliver the heat as efficiently as possible, emphasizes Schlemminger
