The third high-temperature heat pump symposium, taking place in person (and not online) Copenhagen, Denmark, on March 29-30, will look at the current technology status, ongoing development activities, challenges and perspectives for the high-temperature heat pump industry.

The symposium will include presentations, case studies, panels and site visits. The event is organized by the Danish Technological Institute (DTI), Norwegian Sintef Energy Research and the Danish Technical University (DTU). It is co-organized by the European Heat Pump Association.

Registration for the event is now open, and the deadline for abstract submission is February 8. Find more information and how to register for the high-temperature heat pump symposium here.

“Utilizing the potential of industrial heat pumps is highly attractive since it allows the [HVAC&R] industry to operate with significantly reduced emission of climate gases,” the symposium organizers said on the event website. “However, there are challenges connected with implementing heat pump technology, especially in high-temperature applications such as industrial processes and district heating.”

Thus, the organizers added, “there is a need for technical innovations to achieve lower specific investment costs and increased energy efficiency while maintaining technical feasibility and stable operation.”

Natural refrigerants are ‘optimal foundation’

Symposium organizers DTI and DTU are both partners in the “SuPrHeat – Sustainable process heating with high-temperature heat pumps using natural refrigerants” project. The SuPrHeat project aims to facilitate the uptake of high-temperature heat pumps with natural refrigerants for electrifying and decarbonizing industrial process heat supply.

Natural refrigerants have several advantages that make them the “optimal foundation” for the development of high-temperature heat pump technologies, according to the SuPrHeat partners. 

“The SuPrHeat project is specifically based on exploiting the peculiarities of natural refrigerants,” the partners explain on the project website. “It was found that temperature- glide matching is a prerequisite for reaching high performances.”

“In this regard, the natural refrigerants R718 (water), R744 (CO2) and the group of hydrocarbons offer the entire range of being suitable for low- to high- temperature glide applications and are thereby the optimal choice for the technology development of high-temperature heat pumps.”
