Abstract:
1. A system for collection of thermal energy, the system comprising: an energy collector, an energy reservoir, an energy collection medium enclosed in a loop allowing fluid flow of the energy collection medium between the energy collector and the energy reservoir in a forward flow from the energy collector and in a backward flow to the energy collector for transferring energy between the energy collector and the energy reservoir, a collector pump configured to control a flow rate of the energy collection medium dependent on a measured temperature of the energy reservoir, a reservoir temperature measuring device configured to measure a reservoir temperature of the energy reservoir, at least one heat pump including a cold side, a warm side, and exchange means for an exchange of thermal energy from the cold side to the warm side, the cold and warm sides being arranged to decrease a temperature of the energy collection medium in the backward flow by operation of the at least one heat pump, and a control unit configured to control the at least one heat pump and thereby an exchange rate by which thermal energy is exchanged between the energy reservoir and the energy collection medium, wherein the control unit is configured to, control the at least one heat pump dependent on the measured reservoir temperature, and start the at least one heat pump when the reservoir temperature exceeds a predefined value, T
