Booster heat pumps to improve efficiency of ultra-low temperature district heating
A research group led by the Technical University of Denmark has analyzed how booster heat pumps may effectively improve the performance of ultra-low temperature district heating networks in colder climates and has found that the refrigerant change plays a crucial role. They also said that powering these heat pumps with renewables may also better integrate clean sources in energy systems.
