The power values and energies during a desorption cycle are presented as an example in figure 5. The power peaks in the adsorber heat exchanger show the heating phase of silica gel from 25 to 75°C between 8:00 a. m. and 12:00 a. m. Because the system was already comparably dry, desorption started only on 75°C. The temperature of the adsorber rose continuously to 82°C and was maintained at this temperature level for 24 hours. The condensation temperature in the condensate heat exchanger was around 23°C. The reduction in power at the condenser heat exchanger shows that there is a thermodynamic equilibrium for these temperatures in the adsorber and condenser at a charging level of 4%. Further desorption is now only possible when the condensation temperature is lowered, which was done in this test and can be seen in form of the second power peak of the condenser heat exchanger. Another possibility is to raise the temperature in the adsorber. A rise in temperature was not possible since the maximum temperature of the electrical flow heater is around 90°C. The average power of the adsorber heat exchanger during the test was

1.7 kWh with a maximum value of 10.1 kW, the average power of the condenser heat exchanger was in 0.67 kW with a maximum value of 4.85 kW.
