Researchers in Sweden have analyzed the impact of a hybrid heating system combining heat pumps and district heating on five real buildings. The analysis showed that residents were able to save up to ...
Researchers in Sweden have analyzed how roll-bonded PVT collectors can act as secondary heat sources in ground-source heat pumps and have found they provide a better performance than conventional PVT ...
The paper compares the performance of wind pumping systems (WPS) using centrifugal pumps, coupled by either mechanical or electrical drives. Mechanically driven systems are more appropriate for ...
