Thermal battery connection
The patented Caligo heat pump application is used to store heat in thermal batteries during weekdays when the industrial plant is operating.
At weekends and during holidays as the operations are shut down, the same heat pumps are also utilised to discharge the energy with high efficiency. In addition, the condensate water is recovered back to the process.
In the example case, the thermal power output is 6 MW, and the amount of water recovered back into the process is approximately 30,000 m3 per year.
