The upcoming High-Temperature Heat Pump (HTHP) Symposium 2024 in Copenhagen will feature sessions on natural refrigerants.
The HTHP Symposium will be held from January 23 to 24 and is being organized by the Danish Technical University (DTU), Danish Technological Institute (DTI) and the Norwegian research organization SINTEF.
The Symposium will serve as a showcase for the latest advancements in high-temperature heat pump technology.
Day one of the event will feature the session “Refrigerants: Which Is the Safer Choice,” a debate on natural versus synthetic refrigerants in HTHPs, with participants still to be announced. The debate will center around topics such as the economics, environmental impacts and safety of synthetic and natural refrigerants.
In another natural refrigerants-focused session, Antti Uusitalo, Ahti Jaatinen-Värri and Teemu Turunen-Saaresti of LUT University in Finland will present “Centrifugal compressor design and loss analysis for large-scale high-temperature heat pumps using natural refrigerants” during a session on the development and testing of turbo compressors. The researchers authored the 2023 paper “Centrifugal compressor design for high-temperature heat pumps,” which analyzed the performance of different refrigerants in high-temperature heat pumps, including the hydrocarbons pentane (R601) and isopentane (R601a).
In addition to the sessions on natural refrigerants, many of the companies sponsoring the Symposium and participating in sessions offer equipment using natural refrigerants, including GEA, Vahterus and TLK Energy.
Helium-based heat pump
Arne Høeg, CEO of Norwegian industrial heat and central heating OEM Enerin, said in a LinkedIn post that he will unveil the performance figures and coefficient of performance for his company’s new helium (R704)-based HoegTemp industrial heat pump at the Symposium. The heat pump is reportedly capable of delivering steam at a temperature of up to 200°C (392°F).
The symposium will also feature insights from leading experts in the field, including Jan Rosenow, Principal and Director of European Programmes at the Regulatory Assistance Project, who will deliver the keynote presentation.
“The potential of industrial electrification is huge,” Rosenow said in an HTHP Symposium 2024 LinkedIn post. “We now need to move from potential to implementation. This will happen if policymakers set the right framework that enables the industry to move forward at the pace required to meet the climate goals.”
The Symposium will also feature sessions on policies and regulations, techno-economic analyses of HTHP systems and experimental validations and case studies from the chemical, dairy and other industries.
