Description

Renewable energy systems based on the combination of solar heating systems and electrical driven auxiliary energy supply systems such as heat pumps are becomming very actractive solutions as the heating and cooling systems in single family houses. The combined solar heating/heat pump systems provide all the needed yearly heating and cooling demand in single family houses. The most widely used energy sources for the heat pumps are the ambient air, ground source heat exchangers or borehole heat exchangers. Heat pumps that use of ambient air as heat source need fans and these can create disturbing noise. Further, heat pumps that use ambient air as heat source run with low efficiency in cold winter periods. The heat source temperature is more stable with ground source heat exchanger or borehole heat exchanger. In systems with ground source heat exchangers or borehole heat exchangers, excess energy production from the solar collectors is also sometimes lead into the ground for recharging the ground heat source. Produced energy that cannot be directly used is usually lead into the ground in order to protect the system from overheating.
The aim of this project is to increase the knowledge of the heat and mass transfer in combined solar heating/heat pump systems that uses of a ground source heat exchanger. Such a system is installed and tested at DTU Byg.
