Summary

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 and planned. For the steady state modelling, a linear dependence of the exchanged heat in function of the average temperature differences (adsorber minus evaporator temperature and desorber minus condenser temperature) is assumed. Based on this modelling a parametrical study is carried out to optimize the 10 kW prototype. Two different adsorber/desorber geometries as well as two hydraulic designs (in the medium temperature fluid loop, condenser and adsorber connected either in parallel or in serial) are assessed.
