DEVELOPMENT OF AN NNOVATIVE 2.5KW SILICAGEL-WATER ADSORPTION CHILLER


Besides (better) utilisation of available solar heat or waste heat, and thereby
reduction of fossil fuel consumption, sorption cooling offers several other advantages compared to conventional compression cooling. Such as reduction of summer peaks in the electricity grid, use of natural refrigerants, and low noise & maintenance. Sorption cooling in
itself is not a new development. However, the development of small scale sorption chillers (2-20kW) is new. This development allows sorption cooling to enter the markets for individual homes, small collective systems and small commercial applications. A second trend is gradual reduction of the driving temperatures of the sorption cycles allowing more solar and waste heat to be used. This article describes the design and performance of a new, innovative 2.5kW adsorption chiller, developed by ECN. This system was built and tests have been performed in a laboratory and in one of ECN’s full-scale research houses.
