Presented at: 9th International IEA Heat Pump Conference, Zurich, Switzerland, 20-22 mei 2008.

Recently small-scale thermally driven chillers have gained a lot of interest because their potential to save primary energy, to reduce electricity peaks on the grids and to improve cost benefit ratio of micro-CHP units when combined into tri-generation systems. ECN has developed a small-scale (output < 5 kW) silicagel-water adsoprtion chiller for comfort cooling for both stationary and mobile applications. At the moment a new prototype is being built (output 2.5 kW) for application in a micro-trigeneration system for residential application. The adsorption chiller will be driven by heat from a Stirling micro-CHP. The total system will be installed in an ECN research house, including the option of so-called solar cooling with solar collectors, and monitored extensively. A search for partners to commercialize the chiller for the built environment is ongoing.
