Optimization of Control Strategies – Switching between Passive cooling and Reversible heat pump


So far analyzed geothermal systems in office buildings differ in their operation, so that a generalization of the results is restricted. Within the scope of the R&D project geo:build ground coupled supply systems for heating and cooling in the buildings are being analyzed both in theory and practice. The focus is to study an adjustment of the cooling modes and switching between passive cooling and chiller mode. Furthermore, a development of energetic and economical sensible combinations of these technologies is foreseen. In the project, four office buildings will be measured and analyzed. The planned targets for efficient combination of passive cooling and chiller mode are not yet sufficiently implemented, despite of implemented improvements.
