Previously the Kalina plant at the Unterhaching site was operated with thermal water as a heat transfer medium. The working medium of the Kalina plant is ammonia water. This mixture enables an optimum electricity yield when using so-called low-temperature heat sources such as thermal water in this case.
Based on the following design data, the gross electrical output is 700 to max. 3,360 kW. Thermal water at the inlet flange of the evaporator Specific heat capacity 4.16 kJ/kg K Density at 20 °C 999.8 kg/m³. Flow rate 125 l/s. Temperature 122°C.
