Listen to the progress of the heat pump
Published: September 2024
The heat pump project is making significant progress, reaching an impressive 150°C. The ultimate goal is 170°C, requiring further optimization of the heat exchanger for efficient transfer. Continued efforts will focus on fine-tuning the system to achieve the remaining degrees.
Collaboration creates results
Published: September 2024
The InterHeat project is transforming green energy through strategic collaboration. Multi Køl & Energi A/S and Danish Technological Institute are working together to create advanced heat pumps that are key to the green transition. Their innovative efforts are pushing the limits of energy efficiency and sustainability.
Heat pump arrives at DTI for testing
Published: July 2024
Earlier in the spring 2024, a very exciting container arrived at the Industrial Refrigeration and Heat Pump Laboratory at Danish Technological Institute (DTI). Inside it - the first of two high-temperature heat pumps developed in the InterHeat project.
New Papers Available Now
Published: March 2024
Currently, two papers have been published regarding the InterHeat project. The first paper "Thermodynamic analysis of a high-temperature heat pump using low GWP natural working fluids for upgrading district heating to process heating" shows that high-temperature heat pump technology using renewable electricity is a promising solution to decarbonize the industrial process heat supply. The paper is published in the Entropie Journal 2024.
The second paper "Thermal design and optimization of high-temperature heat pump integrated with district heating benchmarked in Denmark for process heat supply" dives into the optimization of several refrigerants including pentane-hydrocarbon and butane and demonstrates that the HTHP technology proves to be a better business case compared to the conventional natural gas and electric boilers. The paper is published in the International Journal of Refrigeration 2023.
