The cooling power of a closed adsorption system is depending on the thermo-physical properties of the material combination sorbent – sorbate. The temperature levels and the mass flow rate of the external heat sources and sinks has to be adapted. Based on experimental results of a 1 kW average cooling power adsorption-desorption test setup using silica gel beads placed in a lamella-tube all-aluminum heat exchanger, a scale-up to 10 kW is proposed, planned and built.
