  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water

    A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...
