Abstract
System for collection of thermal energy. The system comprises a heat pump (2) and an energy collector (3). The heat pump is adapted for transportation of thermal energy from a first heat exchanger (4) to a second heat exchanger (5), and the energy collector comprises a wall forming a duct (7) for conduction of an air-flow. Furthermore, the first heat exchanger (4) is arranged in thermal communication with the duct.
