First heat pump arrived

In March 2024, the first of the two high-temperature heat pumps developed in the
InterHeat project arrived for testing at the Industrial Refrigeration and Heat Pump Laboratory at DTI, Denmark.

Progress of the heat pump

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.

Integration at process level

A high-temperature heat pump system is integrated at process level in a protein powder dryer. The system uses hydrocarbons and is demonstrated with a capacity between 300 kW to 500 kW.

Integration at sector level

A high-temperature heat pump system is integrated at sector level as a booster for a district heating system for supply of process heat of up to 160 °C. The system uses hydrocarbons and is demonstrated with a capacity of 1.3 MW to 1.5 MW.
