Based on experimental results gained on a single vacuum chamber 1 kW average cooling power closed adsorption-desorption laboratory test rig, a scale-up to a four chamber 10 kW cooling power demonstrator was carried out. This scaling comprised the water sorbate evaporator and condenser design as well as two combined adsorber/desorber heat and mass transfer units. In this paper, the design of the 10 kW prototype is described and technical decisions that were done as well as component choices are documented.
