13 How a heatpump works

14 Design of geothermal heat pump systems basic principles Best possible insulation of building Optimized design of the hydraulic; supervising construction and adjustment of the hydraulic system High number of operation hours per year Underfloor heating Heat pump system Lowest possible flow temperature for heating circuit Heat pump power as low as possible = rather under dimensioned Horizontal ground heat collector Baskets Least possible number of boreholes = rather deeper boreholes instead of additional boreholes Borehole heat exchangers Energy piles Slit walls Groundwater well Heat exchanger as big as possible = rather over dimensioned 14

15 Situation in Geothermal Germany 15

16 Case study: Exzenterhaus Bochum Geothermal supply of the Eccentric house Office building with 5,000 m² total floor space 15 floors Total height 89 m Pre-stressed concrete slab Glass front 16

17 Bivalent heating and cooling system Heating system Base load by geothermal energy Concrete Core Activation Peak load by district heating Radiators and Ventilation system Cooling system Base load by geothermal energy Concrete Core Activation Peak load by chillers Ventilation system 17
